I’m about to change the gear oil in my '03 5-speed. The owners manual specifies 75W-90, API GL-4 or GL-5. My local store has Valvoline 75W-90 High Performance Gear Oil (GL-5). A banner on the label says ‘Limited Slip’, and online they say it’s good for, “All hypoid differentials (conventional and limited slip) and manual transmissions in passenger cars, light trucks, sport utility vehicles, vans and heavy-duty trucks where an API-GL5 or MT-1 fluid is specified”.
Normally I wouldn’t pick one that specifies it’s for limited slip. Is this oil ok for my tranny?
Thanks
