These synthetic gear oils provide performance features that make them suitable for use in the following:

$30 75W-90 Synthetic Gear Lube - 1 Quart (Pack of 2)

75W-90)

I agree im going full on Super tech from now on, paying too much for fancy boutique oils doesn't make much cent$ to me anymore, ive tried all the highly touted gear oils and none have shown to be any better than Super tech

 

use it, 16 gallons is enough for 2.5 services at 30k miles

 

Okay thanks for that but still makes no mention of why 85w140 would be required after the ECGS bushing mod

 

that’s what she said
