Oil Change

[Terry,NJ]

My friend Bob, told me how they had done an experiment with old cars by draining the engines and running them without oil until they seized. The ones with STP would always run longer than the ones with out. Also, somewhere I heard that STP would Cling to the engine parts longer to provide better lubrication at start ups after long periods of inactivity.

Was it high detergent STP?

Personally I would suggest some AMSOIL 30 weight Z-ROD oil. It was specifically made for vintage cars and has some great data to go right along with it. Albeit it is synthetic. However I still have a few friends that run it in their much much older cars and absolutely love it.

Someone needs to be bold enough to run just plain liquid detergent in the crankcase and report back the results; we need to gather more data before we jump to any conclusions pro and con detergent. And someone needs to try just plain brake fluid, since that has come up, too. Something has to be better than motor oil!

I would like to thank all those who posted some of the technical information to this thread. I know I have learned a lot about the "scientific" considerations about oil and how it works in our engines. Many things I had never known or considered and had never heard the explanations for the various weight oils, types of oils and etc.

I know people on this site get tired of hearing about "what oil to use in my A" but rarely do we get a technical reason as to why "I" use this oil. A number of the posts on this thread does enlighten us as to what oil does to our engines and thus gives us some options as to what we should do. Thus again I do thank those "engineer" type people who responded with some scientific explanations about oil. I am sure people will still use what oil they have always used but at least now they know how that oil effects our engines.

Thank you again.

I cain't believe I read this WHOLE thing, AGAIN!!!!! I'm pathetic!!
Just use a QUALITY multi-grade, detergent oil, of the proper viscosity for the weather temp ranges where you live!
Do change your oil at proper intervals. Some folks I know who "CROW" about proper maintenance, are too blamed LAZY to change their oil, unless, ALL OF A SUDDEN, it's BELOW the LOW mark!! Some complain of hard steering, then find that the tires only have 12# pressure & NO sign of fresh grease around steering & suspension stuff!!! Complain of runnin' warmer than usual, then find it just needed the water topped up!!!!
"TALK" IS CHEEP!!!! Bill W.
