What the difference between Mobil 1 75W-90 and...

Mobil 1 Delvac 75W-90? Which is the better product?

 

[clinebarger]

Mobil 1 75w90 has limited slip additive, Mobil 1 Delvac does not. Mobil Delvac 1 has a lot of builder approvals.

Mobil 1 is much easier to procure. You can't get Delvac in quarts, since they expect it to be put in differentials with capacities in gallons.

Made M1 to D1 switch in my G80 two years ago … no change in operation of the locker so I’ll leave the D1 in another year

Not true! I used to buy it for my Volvo Penta stern drive. I have a quart of it in my garage right now.
