Synthetic Oil How does everyone feel about running synthetic oil in their A's. I have been running 30wt. Diesel oil but now see people are talking about running synthetics. I don't think they come in anything but 5-20 wt.? What do you guys think?

Re: Synthetic Oil I’ve been using Walmart 10/30 Synthetic oil for 2 years now. I did have a lifter tap now it’s gone. I don’t know if it fixed it, but the A seams happier :D :D.

Re: Synthetic Oil Mobil One 10W-40 High Millage - Synthetic in all my cars including the '31 Pickup

Re: Synthetic Oil I use in my new A a 20W/40 synthetic oil at 1500 mls. In my 47-er Traction I drive now 10 years a 7.5W/40 synthetic at 60.000 mls. Low ash, clean piston"heads" and spark plugs.

Re: Synthetic Oil I run synthetic in everything. even the lawn tractor.
price at this point is almost identical to reg oil and it lasts 3x as long. |
Re: Synthetic Oil Ronn, you wrote <... and it lasts 3x as long. ...>NO! You must change every oil in short intervalls to take out the dirty dust, because there is no filter!

Re: Synthetic Oil The stuff is too expensive for me. I'll keep using the stuff that was good enough for Pop & Grandpop.

Re: Synthetic Oil I have read that when used with older engines synthetic oil can damage gaskets and seals causing the potential for leaks.
I do use synthetic in all our modern cars. Really great stuff. Enjoy. |
Re: Synthetic Oil Rotorwrench, I see you here in the forum as a very versatile professional good technical man. See synthetic oils only so, that they burn with much less residue. The engine and combastion chambers stays cleaner.
This is the main reason for me why I use synthetic oil. |
Re: Synthetic Oil WHN, this only applies to sealing material (shaft sealing ring) before the 1970s. Thereafter, material (eg. 'Viton'), which is compatible with synthetic oils, was used.

Re: Synthetic Oil 1 Attachment(s)
Synthetic oil ?
I seem to have a different opinion to other users. A buddy spoke about the positive benefits of synthetic oil in his aeroplane so I tried it in mine. The oil remained clean and after quite a number of hours I realised it wasn’t scavenging the carbon. I returned to the usual detergent oil and it got very black very quickly. I continued to change frequently until normality returned. It is for this reason I never used it again. Has the composition changed? Or am I being obstinate? I have an open mind to logical criticism and positive suggestion. |
Re: Synthetic Oil I use Mobil 1 Synthetic in my Model A's and my 39 Ford V8. I have been running 10w-30, but I want to change to 10W-40 as Ford recommended 40w in the summer. Maybe it doesn't make that much difference? FWIW, Ron Ehrenhofer, who is the technical guru for the Model A News for MARC, uses synthetic in his cars.

Re: Synthetic Oil No need for Synthetic Oil in an A but if you must I'd go for Mobil 1 15w-50 which is great for both cool and hot weather and this oil has a very high ZDDP content if that also matters to you. It's sold a Walmart for about $23 a gallon I think.

Re: Synthetic Oil It helps to keep the turbo cool.

Re: Synthetic Oil as I said, I run synthetic in everything and it lasts 3x as long as reg motor oil. I chg my oil every 2k miles
buying it for 3.15 a qt at walmart. for the guys that say they cant afford that, well maybe they cant afford an A. "ignore the noise around you" |
Re: Synthetic Oil Quote:
I learned a long time ago not to use synthetics in the helicopters. They would never last on the stuff. Aeroshell W100 or W100+ are the most common used. The plus has TCP as an additive for Lycoming engine cam follower well being but can not be used in engines with integral clutches or overrunning clutches since they might slip with that oil. Straight mineral is only used for break in. Automotive engines have no real comparison to aircraft engines other than they are a reciprocating piston design. |
Re: Synthetic Oil Synthetic is too expensive for me! I run 20-50 Pep Bros. or NAPA. I've run 15-40 in my diesels since '82, one ran 262,00 before I sold it, another 206,000 never any trouble. I run my '13 power stroke 7500 miles between changes, as per factory recommendation. Zinc is not important in A's, wasn't when new, isn't now because of the steel, not cast iron, cam and low valve spring pressure. Detergent is important, never run without it. Additives are not needed either, another waste of money.
