You know how some newer motors require lighter weight oils such as my DD calls for 0w20 and my wife’s car needs 5w20. She has a load of miles on that car and has a history of letting her car go dry on a few occasions. * I made her be responsible to check and add her own oil in case anything happens to me she can do some things on her own. She could just as well have it checked by someone else but it’s not like the old days when they performed services at the gas stations. The guy pumping gas would ask to check your oil and clean your windshield. We have one or 2 service stations (8 miles apart) that I can think of and even then I don’t know if the guy pumping will check your fluids if you ask.
So if you suspect a high mileage motor that calls for low weight oil has considerable wear, does that motor derive any benefit to using the next heavier weight oil? To fill the larger voids left from worn down parts?
I was reading my owners manual and the manufacturer explains the lower viscosity oils are needed to adequately flow between today’s close tolerance parts and to improve gas mileage. It just made me think in terms of what I just said about wear. Discuss -
