what to do with 85W140

[2EHA]

got a ton of this stuff laying around from a semi truck repair shop.

what can i mix up to something suited for a normal car’s diff or a manual trans in all weather conditions?

most likely not good in any manual transmission wont have the right FM's (or lack of FM's) for good shifting.

you could just run it as is in RWD applications that spec 75w140. but in applications that call out 75w90 you might lose more in gas $$ than just buying the supertech 75w90 for 5$

Offer it for sale to people with older trucks and equipment.
