I want to see someone try 75W140 gear oil just for kicks. Right before taking the car to the junkyard I suppose.
Thickest weight oil you used

Only the adds would be incompatible with those required in engines.
Viscosity is about where this thread is talking

Mobil Delvac 1 5w-40 in my Beetle TDI. My gassers got 5w30 in everything from 1988 to 2006, and 0w30 since then.

I don't get that chart. How can the 75W have the same viscosity as 5W or 10W? Doesn't make sense.

10W-40 MAxlife in my old cavalier.

Or 85w-140 for that matter. I use Torco 85w-140 in the diff on my GTO and I have to heat it up to get it to pump into the diff. Mobil 1 75w-140 was noticeably much less viscous when trying to fill. The Torco is non synthetic though. I couldn't imagine a motor oil of that viscosity.

I ran 20W50 in almost all of my older muscle cars/hot rods when I had them. These days seeing as I only drive new vehicles I run what the mfg calls for which has been 5W20 and 5W30 for the most part. If I ever get another muscle car/hot rod I will run 20W50 again most likely.
0W40 in my M3
Mobil 1 0W-40 in my Integra.

I used to think the same. Then on BITOG, I learned that the scales used for viscosity on gear/transmission oils are completely different than for engine oil.

10w30 I believe.

GTX 20W50 in a '79 Caprice 305ci V-8 for 12 years. The recommended 10W30 went through it like carap through a goose. The heavier oil did not and it still started fine in temps in the low teens. The old underpowered 305 still ran as new when I sold it.
In my pre BITOG days I ran 5W-50 Syntec oil in my 1 year old 1996 Contour with the 4 cyl Zetec. Nothing horrible happened as far as I remember. I know the once free revving Zetec was not so free revving with the 5W-50. My mpg also shrank noticeably. After approximately 2 years I went back to various synthetic 5w30's and the car revved freely again and my mpg shot way up. To this day I'm still running synthetic and synthetic blend 5w30's and quite happy to do so. Even though my Zetec was finally back spec'd to 5W-20 I'll stick with the Synthetic 5w30 as I really enjoy winding this engine to over 6,000 rpm a bit too much
. Since Ford waited some years to back spec the Zetec after back spec'ing most of their other engines to 5W-20 I'll stick with the 5w30.
