Best rear end lube

[TTimmons]

I would be interested in seeing the actual temps between the 75-140 and 75-90 if anyone could provide them. While towing a trailer would be even better.



Thanks guys!

I've had great performance out of the Mobil 1 75/90. Kinda expensive @ $10 per quart but lasts a LONG time. The factory 15K intervals are absolutely ridiculous if you have a good oil like Mobil, I am doubling my intervals to about 35-40K.
