Is limited slip gear oil ok for '03 Tacoma manual transmission? Sign In

I'm about to change the gear oil in my '03 5-speed. The owners manual specifies 75-W90,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

I have found that they make very few lubes for limited slip these days. Most rely on you adding a friction modifier to make it acceptable for limited slip.

If it states it can be used in limited slip, it likely already has the additive.

Uggh! Was just watching this question would now bug me if you found a tag or part # listed might pay the dealer prices for less chance of being wrong. As HT said there is or was an additive and have it on hand now!
Trouble is this may not use friction plates rather the same diff. with using brakes to center which wheels will do what not that likely IMO but not out of the question yet to me.
Just a question from your owner's manual if you believe that is the correct one specific to this truck. Does it even state gear oil for this requires changing at an interval or maybe plain state that it doesn't? Sorry to add to the question would be pulling hair out to find out just like you are,
