Classic/Antique Car Repair: 1929 Whippet, antifreeze mixture, gasoline additives


Question
QUESTION: Brad, I just purchased a 1929 Willys Whippet in pretty good shape. I do need to replace the roof and do some minor electrical troubleshooting. I am using 30W non detergent oil and regular gas. Should I be using any additives and should there be an antifreeze mixture in the cooling system? The information I have (1920s) calls for an alcohol mix. I want to keep this stock including 6V electrical. Any comments?



ANSWER: Unless you are going to drag race the car or use it as a farm tractor to plow the fields it will run just fine without gasoline additives. As far as anti freeze goes a permanent anti freeze mix will reduce the chance of rust in the cooling system but an additive will work as well. I would prefer the additive. Do not use alky in the system as that stuff when leaking can cause a fire. I have no problem with a S.W. detergent oil for this car as long as the oil pressure is up in the normal range. And keeping the 6 volt system is a smart idea.

QUESTION: Brad< I assume you mean a sinle weight detergent oil that would be adjusted according to the seasonal temperature. What additive would you prefer over a permanent anti freeze?

Answer
Yes, a single weight. My 41 Ford that was overhauled uses 10W-30 and runs just fine. As for the radiator if you are going to run the car during freezing weather then you will have to use antifreeze. But for summer running I use a product from NAPA, rust inhibitor #13, a product made by Mac's. I have been using that stuff for 50 years.
