Why is it hard to find 30w oil
Hi Ford Barn Members:
Does anyone out there knows why is it getting extremely hard to find 30W oil anywhere? I live near Columbus, GA, and cant find it at auto parts stores, Walmart or Tractor Supply.

Re: Why is it hard to find 30w oil
The theory is that multi viscosity oil is a superior product and single weight oil is unnecessary. I use 15-40 in my A.

Re: Why is it hard to find 30w oil
I have a worn out modern car with 200,000 miles on it. 40 or 50 weight with a bottle of STP keeps the oil in around town but on the road I still need to add a quart every 400 miles. These days finding 40 or 50 at an auto parts store is almost impossible.

Re: Why is it hard to find 30w oil
I was at my local O'Reilly recently and the manager said the state of CA will not let them sell nondetergent oil. They can't order it special for anybody. Not that I would ever use it, just saying.

Re: Why is it hard to find 30w oil
Try some independent motor supply stores. I use 30 wt ND in my T and A and in the overdrive of my '58 Austin Healey. I have three stores here where I live in Maine where I can get it but all are independents, not big box or chain stores.

Re: Why is it hard to find 30w oil
Non detergent oil is about the worst thing to run in any engine. Use it in your compressor. Do the engine a favor and take advantage of good lubricants.

Re: Why is it hard to find 30w oil
I recently found Pennzoil 30 on the shelf at Blain's Fleet & Farm.
I assumed it was available there because of the 'Farm' nature of the place. I prefer straight 30 weight because it's the same starting and finishing. Plus it's 'A' 'seasoned' engine. Multi-weights are superior IF you are using a thermostat in your Model A. $.02, JB |

Re: Why is it hard to find 30w oil
I got 30W off the shelf at my Fred Meyers (Krogers in some parts of the country). Look at Walmart. I have found while the brand selection may not be as good, you can sometimes find oil for less $ at places like what I suggested, rather then part stores.

Re: Why is it hard to find 30w oil
I used to look for 40W but have given up and use 20W50.

Re: Why is it hard to find 30w oil
The word "detergent" offends the free range snowflakes

Re: Why is it hard to find 30w oil
I use 30 wt. non-detergent oil in my '29 Chevy. The motor is original (not rebuilt) and had non-detergent in it when i bought it. My '31 "A" roadster
uses 30 wt. detergent oil. Has an original (not rebuilt, as far as I know) "B" block in it. The Chevy has no filter system with the '31 roadster having one of the "by-pass" filter systems. I was under the impression that non-filtered oiling systems used non-detergent oil. So any contaminants in the oil would drop out into the pan before the oil was recycled back through the engine. And detergent oil suspends any contaminants within the oil so it can be picked up by a filter. I don't know how true these are, but they are what I go bye. I also use STP in both cars. Bob-A |

Re: Why is it hard to find 30w oil
Are you sure Walmart doesn't have it? I recently saw both detergent and non-detergent 30W oil there. Try looking in the lawn mower section and the 4 stroke engine section rather than the auto engine oil aisle. Lowe's and Home Depot I think also have it.

Re: Why is it hard to find 30w oil
Hmm, strange. TSC has both detergent and non-d in 30w around here. i think Walmart does too as other parts stores. I no longer use it in anything, but, I know I've seen it.

Re: Why is it hard to find 30w oil
Thirty weight viscosity oil was the thing in 1930. Detergent oil had not been even conceived, let alone invented. Same thing for multi-viscosity. From my perspective you should be using a modern oil. New engines are much more demanding than our old flatheads and lubricating oil technology has moved ahead with those designs. I know it's not a Model A, but I have a '48 F-1. Its owners manual recommends using "Heavy Duty Motor Oil" stating "The heavy duty motor oils contain detergent compounds and tend to hold in suspension the foreign contaminants which normally would deposit on the engine parts." It goes on to say "This term shall be used to designate an oil having proved oxidation stability, bearing corrosion preventive properties, and detergent dispersive characteristics. Oils of this type are generally suitable for use in both high speed Diesel and gasoline engines under heavy-duty service conditions."
Detergent oils were just coming on the market at this time and were considered in the high end of the market. Now, of course, all regular oils are detergent. Detergents in the oil prevent the formation of sludge, which I consider highly desirable. If you pull the dipstick on a modern engine the oil will not show any sludge formation. Wouldn't you like your 4 banger to be like that, too? I use 20W-50 multi-viscosity. Others will have different opinions, but don't fall into the single viscosity trap. Again, following the above logic, modern multi-viscosity oils maintain the desired viscosity over a wide range of temperatures. These were not available in the old days. Then there's the Zinc trap that old-time "gurus" fall into. This has been the subject of much heated discussion. In my opinion there is more than enough zinc and similar additives in modern oils to keep your banger happy. Does a Model A place demands on motor oil that are more severe than a modern high performance automobile engine? JMHO. |

Re: Why is it hard to find 30w oil
I'm with DD931 on most suggestions. I however use 10W-30 Mobil 1 full synthetic. Where I had my short block rebuilt recommends 10W-30 and claimed synthetic is not needed. Recently I drove my Model A to the MAFCA National Convention in Reno, and my engine did not use any oil. Let me ask you this, how much does a full tank of gas cost when you fill up? I filled up last night with 9 gallons and it cost more than the 6 pack of oil I bought at Costco before I filled up with gas. Costco gas where I live is also advertised as Top Tier gas btw. How many tanks of gas are you going to buy in 3,000 miles? I think it's a small amount of money in comparison to the price difference in synthetic and regular detergent oil.
I spent a lot of money on my Model A engine rebuilding it and I intend take as good of care of it as I possibly can. Use what you want for oil, that's my preference. Lastly, I noticed something interesting. On one of those new bottles of oil I bought from Costco reading the label in small fine print states, " Continuous contact with used motor oil has caused skin cancer in laboratory animals". Doesn't say anything about CA or birth defects. |

Modern multi weight detergent oil is way better than non detergent single weight. Most of your engine wear happens at startup. Why would you not want the oil to flow quicker especially on a gravity splash oiling system?

Hi M2M:
I have looked in all those stores you suggested and they don't have it here in Columbus, Georgia.

Walmart & NAPA have 30W nondetergent oil. If you can't find it on the shelf ask for it.
