Do you guys realize and understand the difference between a 90 , 85 and 80 ?
Differences are barelly noticeable.

This is why they choose 75w90 because it will cover the bases of all other viscocity's

Shifting is very smooth, no more notch/grind second gear. I paid around $27/qt at GM dealer, but you can buy from online for cheaper( cheapest one was...3qts for 50~60 bucks shipped? I dont remember)
