Question 75-90 or 75-140?

Coming from a 2wd 1500 I used Mobil1 75-140 since it called for it and the 2500 calls for 75-90...

Not really a problem to switch but I would think the thicker the better? and I have 6qts of the stuff at home not used... No receipt...

Being I live in California, Light to moderate off road 2 or 3 times a month, highway and very light towing (family boat) wouldn't 75-140 work?!?!

What do you put in your front and rear diff?

75 - 140 will be fine. It is used more by people that tow real heavy. I run the 75-90 front and rear. I don't tow heavy but I do have higher temps in the summer time but don't have any issues.

it is not going to be a problem. Normally only the folks that tow heavy in hot climates use it. I would typically say just use the 90w if you were buying it, but since you need to use the 140w up, put it in and don't look back.
