Model A Oil with Zinc or other Additives
Not trying to hear what kind of oil is used by humpteen different Model A owners; or even start a new thread or war on wild "guesses" as to which Model A oil to use.
But, after reading Pills most "serious" January 23 2015, 10:34 a.m. thread below entitled "On Model A Oil", I looked up the "Shell Rotella 5W40 Oil" that I have currently used for the past 600 miles on my clean rebuilt Model A engine. Shell's Rotella 5W40 advertising literature "again" appeared very encouraging. This is only intended to "share" what was reported after researching Shell's "Contacts", & calling a Shell Technician Service Representative named Larry, at 1-800-237-8645. Larry said as far as he knows, Shell did not conduct Shell Rotella 5W40 test on vintage engines with Babbitt bearings; however, they were all informed that the detergent oils with zinc additives or even "other" non-detergent additives were designed for light duty or heavy duty "modern" engines with insert bearings. They were cautioned that the zinc additives or other modern oil additives "may" have long time "adverse" chemical effects on "soft" metal Babbitt bearings used in vintage engines as late as the 1950's. He was honest enough to report that he did not have information as to which non-detergent oil with "additives" was recommended for Model A Babbitt bearings. Always interesting to speak to non-salesman-oriented manufacturer's trained technicians. |

Re: Model A Oil with Zinc or other Additives
Hi -
Great success with Quaker State DEFY motor oil. 10/30 wt. and the little FORD thrives on it. Available at major discount retailers - specifically noted as ZINC enriched for older/ higher mileage engines. Love it and so does "Annie" our '30 Deluxe Coupe. Be well - SHEC SORRY - Upon a reread of your header - I should not have replied as I did. Did not intend to step on the Rotella only discussion. Regards and apologies - SHEC |

Re: Model A Oil with Zinc or other Additives
The A because of low valve spring pressure does not really need the zinc additive.

Re: Model A Oil with Zinc or other Additives
I use straight canola oil in my model A. That way when I go on a picnic or tailgate party I can drain the hot oil and fry up a big batch of french fries, then pour the oil back in the engine to go home.

Re: Model A Oil with Zinc or other Additives
there is a lot of misunderstanding about detergent oil and babbit, detergent does not hurt or destroy babbit, modern engines use babbit on all there bearings, rods mains, cam and these engine run for over 200,000 miles with minimal wear, in fact all manufactors don't just recommend detergent oil, they specify it

Re: Model A Oil with Zinc or other Additives
In continuing to try to remain serious with a Model A oil discussion, (LOL); not just on this Forum, but if one looks around, just about every one of the Forums associated with vintage engines, it appears they "all" have the same similar types of comments on "oil"; i. e.:
a. Many are anecdotal; and, b. Many are just presumptive guesses; and, c. None were found thus far with names & phone numbers of individual petroleum technicians who provided recommendation information; and, d. None so far found with their recommendations backed up with laboratory performed tests on vintage engines supported with written documentation. Found endless internet articles on oil from petroleum manufacturers, SAE, API, etc., etc.; ......... sent emails to a few petroleum manufacturers & awaiting responses to share, (if any) ............ but so far, only found one (1) Petroleum Manufacturer bold enough to recommend their modern detergent oil for classic cars as follows: -------------------------------------------------------------------------------------------- CARE FOR YOUR CLASSIC CAR There are two kinds of cars in the world: those that need Havoline® High Mileage - and those that will. Whether you're still driving that old ride your cousin fixed up in high school, a recent model with high mileage, or a true, vintage collector’s item, cars get older. It happens. And as your engine ages, seals and gaskets can become worn and leaky. That can be a problem, particularly if your classic is post warranty, which - chances are - it is. Havoline with Deposit Shield® High Mileage Motor Oil provides extra treatment for seals on contact, protecting and preventing leaks. Havoline with Deposit Shield High Mileage Motor Oil also includes a burn-off inhibitor that reduces excessive oil consumption. Give it the extra care it deserves. After all, it’s gotten you this far. It could be just the beginning. ------------------------------------------------------------------------------------------------ Maybe not much help to respond to "Which oil to use", but maybe somebody can find a few more petroleum manufacturer "recommended" modern oils for our classic cars.

Re: Model A Oil with Zinc or other Additives
yes, canola oil also reduces LDL cholesterol thereby reducing the probability of a heart attack or stroke in your engine. Of course, many folks would like it if their engine had a crank that was stroked.

Re: Model A Oil with Zinc or other Additives
I believe it was DA Refinery in Indianapolis that is offering motor oil for antiques with increased ZDDP. Check them out. Rest assured.
OR Valvoline Racing oil or Brad Penn oil. |
