So, I went to pick up gear oil for my truck today. I was going to get the synthetic stuff, but decided just to be cheap and get plain old Valvoline white bottle. That's what I have in there now.
For some reason, I think I was thinking about my old truck, I got 75w-90 and 80w-90. I think the previous truck spec'd 80w-90 in the rear end. This truck does not.
I talked to some local Chevron dealers lately, and though most of them only deal in 5-gallon buckets, one sells by the case of quart bottles. Chevron doesn't make a dino 75w-90, so it is considerably more expensive, but they do have Delo ESi dino gear oil in 80w-90 for something like $54 for 12 quarts. I need just a hair under 6 qts per change, so that would be perfect for my next two changes--and really cheap!
I think Valvoline is $7/qt for 75w-90. It doesn't say synthetic, so I assume it's not, although most 75w-90 apparently is synthetic.
I plan to probably change every 30k as the manual specifies until out of warranty, then probably change to a 50k interval with synthetic. I don't currently tow (we'd like a teardrop or popup camper someday), but we do occasionally take long trips or camping trips with the truck loaded down.
The manual specifies 75w-85 in the front & rear diffs, and 75w-90 in the transfer case (all 1.1 quarts). Since it seems like 75w-85 is a Toyota-only thing, I'm not so sure I want to pay that.
Or, should I just blow the money and get a full synthetic? The budget right now is extremely tight, which is why the Delo is very very tempting.
One last thing I noted about the Valvoline. The 75w-90 bottles only list it as meeting GL-5 and MT1 spec, whereas the 80w-90 lists a whole boat load of specs, including a MIL spec. I noticed some of the synthetic 75w-90's said this, but the Valvoline white bottle 75-90 did not. Does that perhaps mean in Valvoline, the 75w-90 doesn't meet these specs if they aren't listing it on the bottle?
