.. "Thicker" =
1) xW-40 *0W-40 and.or 5W-40 Full Synth, 10W-40 Blend, or 15W-40
2) 15W-50 Full Synth
I have noticed that those that have used "xW-40" Oils.. Conventional, Diesel, Blend, Old, New, Whatever...
.. Have cars that last 200,000 miles or more...
.. Much like my parents 1982 Oldsmobile DELTA 88 Royale Brougham with the 302... Over 350,000 miles, ran for CONSIDERABLE time after that...
.. and i Know its Oversimplification and they tend to be V8s or V6s that report the long lasting.. but IS there a connection where 40 beats out 30 in this Department?
OR can it last -exactly the same- on a nice 5W-30?
You all know my car.. Im asking more in terms of Engine Health and the "Heavier" Oil, assuming it doesnt get too cold.
My understanding is that if the Thicker film does NOT Shear or Foam, ait will provide the moving parts a thicker Cushion.. is it really that simple?
I also seem to recall EVERY Car with an Oil Pressure Gauge (1991-1994 Blazers S-10, the Delta 88, etc) always showed LOWER Pressure with 10W-40. Thicker Oil.. Less Pressurization, due to more Space taken up by the Film, yes?
