oil recomendations

No, you are correct, you did not say that multiweight 'thins out from heat'. But you did say it 'thickens up', which is incorrect. And that statement is what I addressed. As for reading skills, and even more important, comprehension, I have always scored quite well.........if it was my 'reading skills' you were lamenting, you are mistaken about that too!

Oils are changing. I like the valvoline racing oils.

Please note here is what I actually wrote. .... and increase their viscosity (thickness for want of a better term here) as the engine heats up.

That done, I accept your technical description of how multi-viscosity oil functions as it heats up. You are correct. This type of oil thins in such a way as to maintain the viscosity of the higher weight number of oil at a given operating temperature.

Thank you for the correction, but as clearly indicated in my original post, I was attempting to keep things simple for the person who started the thread because he is obviously a novice at such things.

Excellent read, heard diesel oils were changing, however; I was not aware this is already occurring.....

 

ive been dealing with 352 390 ford motors daily for the last 25 years . use a good quality straight 30 wt oil thats all it needs and was designed to use .change it at least every 3000 mi . no additives etc, a waste of money

 

I've heard the diesel oils are changing also, i recently change over to bradd penn oil it claims to have all the stuff older engines need.

Thanks guys!!! 20/50 seems to be the perfect match running great on startup and everything...also poured ATF down the carb... runs like how i imagine it would new!!!

 

Thats what I use and also a good wix or napa filter same thing. Get the filter with out the bi-p*** at least on chevys thats the way it is.
