Don't be fooled, Shell Rotella T, the original Rotella T is exactly the oil that everybody bought and used (irregardless of name brand) up until about 1980 when the SAE/API specifications were updated due to catalytic converters The original Rotella T may be popular in Diesel engines today yet it was amongst the most popular SAE/API spec gasoline engine oils ever run threw Detroit steel up until we were handed the new spec oils 35 years ago. Our Flatheads have not changed and neither has the original Shell Rotella T oil. Almost every oil/manufacturer on the market today has updated their current engine oil offerings to newer SAE/API specs except for a few like Shell, Which still offers us the original formula of Rotella T that would have been/is equivalent in spec to/as pre 1979~ Chevron Delo, Royal Purple, Mobil Delvac, Valvoline premium, Citgo Citgard, Connoco Phillips 76, Castrol Tech etc. The newer Rotella T3 is the original blend somewhat updated but still to pre 1980 API/SFI specs featuring the original high ZDDP and high phosphorus contents that all oils held up until the advent of catalytic converters. If you wish to run the closest thing to what every piece of American steel was born and bread on for more than 75 years, then you will not get anything closer than the original Single grade conventional oil—in SAE 20, 30, 40 and 50 Rotella T with it's pre 1979~ specifications that is still popular on the gasoline/racing/turbocharging/diesel/farm/motorcycle market today.. (Or T3 in multi-grades) Personally, I have been running Synthetic oils in almost every vehicle I have owned since 1984 including and at times, Model A's, Flathead V8's and always daily drivers. I have owned about 65 classic cars and trucks in that time and generally commute (up to) 60,000 miles a year with daily drivers. I do oil changes on vehicles every September before the snow flies, (Including the Flatheads and Bangers) and this is what I bought to get me thru winter 2015. My 28 Model A got the Rotella T3 and the Flathead V8's all got synthetic. I have a 1979 LTD Special (Fire Chiefs Car with lights) that has a leaky rear seal so it got regular non synthetic oil and will do so until I fix the seal. . Don't be scared of Rotella T, Rotella T3 , Chevron Delo, or the excellent money saving Synthetic oils that you can run for 10,000+ miles whether it's your daily driver or even in Flatheads. Consider this; the new Synthetic oils are being used in Heavy Truck applications today and the manufacturers recommended oil change interval on most semi's is between 25,000 and 40,000 miles using one oil filter. All Synthetic oils surpass Rotella T in engine protection while offering superior adherence to on-spec weight/viscosity for many more thousands of miles/hours. That is to say that they will remain to be an on spec W30 viscosity oil for 10 times longer than a similiar non synthetic 30 weight oil (which tends to thin rapidly with age after roughly ~2000 miles). http://www.machinerylubrication.com/...ange-intervals Rotella T and Rotella T3 is a high ZDDP and High Phosphorus Content oil compatible with older engines with or without flat tappet cams and/or hardened valve seats just as it was prior to 1980. ====================================== Shell Rotella T From Wikipedia, the free encyclopedia Shell Rotella T is a line of heavy duty engine lubrication products produced by Shell Oil Company. The line includes engine oils, gear oils and coolants. The oil carries both the American Petroleum Institute (API) diesel "C" rating as well as the API gasoline engine "S" rating. Ratings differ based on the oil. Rotella oils like T3 15w-40 meets both the API CJ-4 and SM specifications, and may be used in both gasoline and diesel engines. However, it is formulated specifically for vehicles without catalytic converters, containing phosphorus levels beyond the 600-800ppm range.[1] Therefore, Rotella is not recommended for gasoline vehicles with catalytic converters due to the higher risk of damaging these emission controls.[2] Newer formulations of Rotella T6 however are API SM rated as safe for pre-2011 gasoline vehicles. Product lineup In the engine oil family, there are four basic oil sub-families:
synthetic SAE 5W-40 meet the newest API certification of CJ-4/SM. Shell is marketing their new CJ-4/SM oil as "Triple Protection," meaning it provides enhanced qualities for engine wear, soot control and engine cleanliness. Shell's Rotella website indicates that on-road testing confirms the new Triple Protection technology produces better anti-wear characteristics than their existing CI-4+ rated Rotella oil. This is achieved despite a lower zinc and phosphorus additive level as called for by the API CJ-4 specification. (The 15W-40 Rotella T with Triple Protection oil has approximately 1200 ppm of zinc and 1100 ppm phosphorus at the time of manufacture.) Competitors Rotella competes with similar lubrication products from other oil manufacturers. Some notable competitive products are:
Though marketed as an engine oil for diesel trucks, Rotella oil has found popularity with motorcyclists as well. The lack of "friction modifiers" in Rotella means they do not interfere with wet clutch operations. This is called a "shared sump" design, which is unlike automobiles which maintain separate oil reservoirs - one for the engine and one for the transmission. Used oil analysis (UOA) reports on BobIsTheOilGuy.com have shown wear metals levels comparable to oils marketed as motorcycle-specific. Use in turbocharged cars Likewise with motorcycles, though marketed as an engine oil for diesel trucks, Rotella T6 5w-40 synthetic oil has also found popularity with drivers and tuners of gasoline powered vehicles that utilize turbocharging or other forms of forced induction. Several owners of high performance model cars have adopted its use due to its high heat tolerance and its resistance to shearing. Rotella T6 is a Non Energy Conserving Oil, and does not meet GF-5 Oil specifications. When Rotella T6 was revised for the API specification(for use in spark ignition motors), its Zinc levels were effectively reduced. Higher(content) Zinc Additives(ZDDP) are required for flat tappet engines and cartridge bearings, which In previous formulations Rotella T6 had desirable levels of Zinc(ZDDP).

Oh, and they call it diesel oil because it is not approved for modern gasoline engines. That doesn't mean it is not approved for old gasoline engines. |

Guys, Shell openly admits that since the advent of catalytic converters, they market directly to diesel owners due to not really having a market of people who don't have catalytic converters. The gasoline market dried up so no real use in pushing it on 2015 vette owners. If it didn't harm your beloved catalytic converters, it would still be an excellent oil across the board (including and most importantly, engines with hi perf flat tappet cams and engines without hardened valve seats). The truth is, all manufacturers reduced the amount of zddp and phosphorus because it plugs your favorite exhaust parts. One last note, Rotella T (the original blend) comes in straight weights just as Henry Ford recommended for our Flatheads. -Straight weight 10w winter and 40w summer Rotella T3 comes in multi weights 10-w30 and 15w40 etc. Rotella T3 includes even more zddp and phosphorus than the original Rotella T straight weights. That's about all there is to it. From the Petroleum Quality Institute; Independent Testing . Last edited by moefuzz; 02-22-2016 at 01:35 AM. |

Only way to get a descent oil is to look for what they call classic oils. My favourite oil went from 1800ppm to 1300ppm ZDDP without any change in the paper specs. Check check again and never trust the seller |

Re: Flathead smoke
mofuzz, A very interesting post. I am wondering: what exactly happens to our catalytic converters using the non approved oil? How does stuff from the oil get into the fuel injection and exhaust system?

Re: Flathead smoke
The cylinder wall are oiled on each stroke and the rings (especially the oil control rings) scrape the oil off. This is not a 100% perfect process and depending on the condition of the engine a very small film is left on the cylinder walls. The same applies to the valve stems.

Joe, the additives that we as old timers like to see in our oil don't burn on ignition. They will sneak past the rings and plug up the converter. No converter, no problem (shhh! don't tell Al Gore!) I tend to believe it's mostly the phosphorus/ash. -High Ash Oils. I think Ash acts as a cushion on valve seats, a job that leaded gas used to help/do. And leaded gas disappeared up here in Canada at the same time and for the same reason, -just as catalytic Converters were introduced because lead also accumulated and plugged up the converter. Honestly, Leaded gas was more responsible for plugging the converter but the tiny bit of ash over 50,000 miles didn't help either so it had to go to. That's why you can still buy old technology oil for diesels, no converters... Now, with the new diesel technology, people are being forced to buy urea right about every time they do an oil change on their trucks. We can Thank the tree huggers for creating a market that sees you pay about $50 extra to fill the urea tank about every time you change the oil or you will void your new A̶l̶ ̶G̶o̶r̶e̶ Chevrolly diesel warranty. .

Re: Flathead smoke
.
......Should probably mention that since about the turn of the century, piston/Oil ring control has improved greatly. For Cars, Trucks, Vehicles, Engines, Engines blocks (at least for those manufacturers who don't sell you $25,000 in total/absolute planned obsolescence attached to 57 cent ignition switches that turn the anti lock brakes and airbags off when driving) and especially =================== ?? =================== Ok, Within The Last 20 Years, Advancements In The Area Of Piston ring and seating has been improved significantly thru tighter tolerances and advances in metallurgy ......to almost eliminate blowby and/or oil residues not being scrapped off the cylinder wall before the big bang. Manufacturers like Ford have been able to dramatically 'tighten up' the combustion chamber as well as extend cylinder wall and engine life. This is one of the reasons that we are seeing many manufacturers recommend 10,000 mile oil intervals today as opposed to the 2500 mile recommended oil change of just a few years ago. Little to nothing is getting past the rings to contaminate the engine oil, oil stays cleaner, catalytic converters stay cleaner, cars last longer, well at least at one Detroit manufacturer they do anyway. I suspect that with today's engines, even a high ash oil could do little damage to the converter. It was mostly the lead in leaded gas anyway and that took years to accumulate. ....Just My Humble Opinion ..And I Am Opinionated -moe Quote:

Re: Flathead smoke
You might try a can of "Sea foam" in the crank. I had some smoking out of my stock '49 after sitting for an entire cold winter. One can cured the smoking. Definitely a temporary fix, but might hold you till you tear it down again. Sea Foam available in any auto part store.

Re: Flathead smoke
Break in oil is probably the best bet.
300 miles or so is the norm for new engines. On old engines with glazed cylinder walls, I have left it in for as long as 600 miles. That particular time I almost completely eliminated the heavy blue haze emanating from one 5 letter word V8 that I had. The link is a few messages back regarding blowby. But for those who missed the link on Blowby And All Things 'Smoke' Coming Out Of Your Engine, Here it is again, -Read up on funny V8 Smoke and how to quite it.... .

Re: Flathead smoke
The API standards or any other standard says what the oil should be able to do...not how it should do it or how the different companies should mix their product.
So the oilcompanies is constantly trying to develope a product that can meet the higher standards at the same time as the old ones and if they can a bit cheaper. The brand name and designation of the oil can remain while they adjust the mix of it. |

Not in America. The rest of the world, yes. API is a governing body and it governs more than just engine oil. Here, The mixture won't be any different than what the label states. If in America, API spec is for a certain mixture, than the label must say so. That's not to say that they may eventually change the blend, But they cannot maintain the specific API designation that is stamped on the cap/bottle and put something different inside. There is no getting around what the spec says unless you Forfeit your prized API License. ---------=================----------- Shell has continually brought new products to the market (just like others) to meet manufacturers requirements for newer engines but they have kept the original progressive upgrades of the Rotella line.

Re: Flathead smoke
moefuzz. Thanks for all of this interesting info. It makes me proud that the API has had committees on Tubular Goods,Well Cements,Supply Chains and Above Ground Storage Tanks manufacturing a safe oil for my car and the environment. I certainly don't want to offend the Environmentalist Wackoes.

Joe, I understand where you are coming from, You being a Fire Fighter understands bureaucracy and/as well as political correctness. This is more for my safety when I am working at 150 feet up a welded steel ladder on an ocean drilling platform on the Beaufort Sea. The codes hold manufacturers accountable for lives that are lost due to Polish quality steel that no one in the USA will use, build, manufacture or incorporate at the cost of human life. Any and all Petroleum production/jobs/wells/platforms/wellheads/processing plants/pressure or boiler vessels, ladders, buildings, under or on sea, land or air built in the USA or Canada will not use steel from certain countries including Poland, Ukraine, China, Korea and others. I have welded 36" I beam for ocean going refinery platforms and at times you can smell strange things in the steel like PCB based coatings or radioactive leftovers that may have been used in the manufacturer/casting/forging of beams/pipes/hollow structures etc. that were manufactured in Czechoslovakia, Korea etc. The API is the law in USA. No one, No company can manufacture or market any product including the above mention oils, petro chemicals, gasoline, steels, plastics etc unless they show proof of adhering to the specifications laid out by the API, which protect, my life, your life, the environment and Innocent victims. --==========================-- What some fail to understand is that companies like Shell etc, are Licensed by the API and must show complete and ongoing analysis and testing under API procedures before they can bring their oil or I beam to market. Once Shell has proven content and submitted all the required test papers/procedures, Only then can Shell APPLY FOR and Be Licensed to market that product. The license can be revoked at anytime and Shell etc. is required by law to test and hold samples of every batch of said product for years just in case something goes wrong. Shell must continually submit samples to the API for testing in order to maintain the right to hold a license to manufacture things like Rotella T rated at API CJ-4 --=============================-- In America, The same specs hold true for steels used on building things like new twin towers that Europeans may wish to fly Aircraft into. -Everybody just seems to think that we are living in bass-ackwards Poland and that you can put up to 35% antifreeze mixed in with the best red wine and no one will notice and no one is accountable when 100 Iron Workers die when the steel from Poland collapses on the 44th floor of the new Tower 2 in New York. 40 years ago I welded on contaminated steel from Czechoslovakia and it was not good then, it does not age well or loose it's radioactivity in 40 years and the pcb will give office workers cancer. This is why WE have an API, and this is why Steel from a select few countries is specified, tested and used by North American manufacturers irregardless of whether the end product is for the USA or the Foreign market. If your Polish product does not meet specifications, America will not license you and they will not use it. But that doesn't mean that the rest of the world holds themselves responsible for "accidentally" putting lead in toothpaste or antifreeze in the best Polish wines. I fully understand that foreigners don't get that fact that without a license, you can't drive a car in America without fear or retribution. But maybe it's OK and nothing happens when you are driving without a license in Sweden and the anti freeze laced polish wine has gone to your head and the Russian quality steering knuckle on your Autogaz 500 fails and you take out a family? -But in America, things are licensed and people are held accountable. jmho, And I Am Opinionated .

Re: Flathead smoke
By the way,
Shell is Licensed to produce Rotella T as API CJ-4 spec which I believe is a 1979 or 80 License/specification based on a 1967 License/spec which dates back even further, to the earliest of Rotella Formulas before there was an API granting them a License and permission to manufacture it for the North American Market. CJ-4 has not changed since 1980. -The license is still applied for, granted and/or up for revocation. If the exact standards are not met with each and every Daily (365) batch, The License is revoked, Which means no oil, no product, no market. -->The CJ-4 Spec is considered by the API to be "On Hold" (not cancelled or obsoleted). This is a good thing for us old car guys. Personally, I tend to believe that the 1967 API license refers to the point at which Shell brought the original 1940's? Shell Rotella straight weight (10w 20w or 50w) oil into the new age of multi-grade oils (10w30 or 10w 50 etc) in 1967. Since 1967, and certainly since 1979 or 80. Rotella T has not changed And more importantly for us old car guys, The API considers it to be "On Hold". . Last edited by moefuzz; 02-20-2016 at 07:33 AM. |
