75-140 Valvoline Gear Oil

I just put this in my Tacoma due to the hot summers in Louisiana. The truck calls for 75-90. Is it ok to leave 75-140 in the truck? Please advise me on this. Thanks

 

Correction: I did use 75-90 squeeze quart container from Walmart. No funnel needed and it works great!

 

I used to run 85-140 in everything year round when the temperature dropped below 10 Degrees F I just drove nice and easy while things warmed up. Never any problems.

I got a 55 gallon drum (free) for helping to clean out a shop when the owner passed.
