Well I just found out that my '09 toyota comes stock with 75w-85 in the front and rear diffs. Toyota even issued a TSB for older yotas to start using the stuff. Does anyone have a PDS on this stuff? Who's making it? It's crazy expensive... Lists fore $31.28/liter. I can get it for $23.50/Litre through a discount yota house. That's borderline insane. Toyota states the reason for this lube is Fuel Economy. Maybe CAFE? I'd love to see a PDS on this stuff. I wonder if it's even GL-5 rated. Castrol's 75/85 is GL-4 only.

Other issue I have is they did not mention running it in the Transfercase. So the Tcase still takes 75w-90 or a 80-90. If you are on a all out MPG war with your truck I would probably fill the Tcase with it also right??

Wow, this CAFE cr-ap is getting ridiculous.

I would use aftermarket gear oil, probably 75W-90 from either Amsoil, Schaeffers or Redline. Each of those oils retails for about $40 a gallon, and sometimes can be found a little cheaper than that.

Differential oil, IMO, is definitely something you want to drain and replace asap.

What engine and tranny do you you have?

Amsoil has two different 75W-90 lubes that are perfect for this - and much cheaper than Toy's lube!

I guess the issue is, if the rear end blows out, or the E-Locker breaks will that give them a way out... I'm sure they'll try it. If I go aftermarket I'll use the Synpower 75w-90 GL-5/MT-1. It's the thinnest Visc 75-90 I've found. The Castrol 75/85 GL-4 is even thinner, can't find a PDS for the Toyota stuff. Not sure if I should blow this Hippie garbage off and use the Synpower. $11.74/qt locally at Napa. How many miles will you have to drive to cover the extra cost of the fluid? It's more than 2x's the cost. Let's save .1 MPG but spend $75 to get it? Not sure the calculator makes sense of that...

Let's say base MPG of 18.5. this 75-85 gives you a 1% gain. at $2.50/gal fuel, and 30k OCI for the diffs. You'll save $40/30k. NOPE. Denied!!!

"Wow, this CAFE cr-ap is getting ridiculous."

It kinda is. I was reading Fords 5w-20 TSB the other day, and it quotes a 0.6% increase in fuel economy (overall for the car) by using a 5w-20 over a 5w-30.

So my 30mpg car now gets 30.18 mpg.

I'm all for progress, but at 20 bucks a liter you'll never get that money back. I wouldn't be worried about the slightly thinner oil and protection, just about my wallet.

Exactly. My diffs need changed due to break-in. Fluid is nasty. so they "need" done. Either A-pay for the $23.50/qt ($31.28/qt list) or B- Synpower 75w-90 for $11.74/qt. I can't see going past a 30k OCI in diffs.

Amsoil recommends both of their 75W-90 lubes for your application. and they guarantee their product. (and not just the refund of puchase price) I know for a fact that
Amsoil will use their clout against any dealer, manufacturer, that contests the performance of the product. Amsoil will even pay for the repair -

A good family friend was an
Amsoil Direct Jobber for 25-30 years and sold ALOT of product. He was also well known by some at corp...

so as long as Amsoil recommends that product for your application...

What kind of MPG gains are we talking 75w-85 vs their old spec of straight 90wt Dino? That would be interesting to know.

I was wondering if I could use Amsoil SVG in my 2009 Chevy
2500 Silverado? I dealer claims that nothing meets there spec for there gear lube 75W-90 (grape juice). Amsoil does have it
on there application list, but has a number in astric referencing
the GM part number.

At the risk of going along with a hijacking, I'm interested in responses to this last post. I'll be putting AMSOIL SVG 75-90 in a couple of '06 Chevy 2500 differentials in a week or so.

From everything I've read, it's an appropriate oil for that application.

Actually for the Chevys you want 75W-110.

Henry Ford used a 600 weight gear lube in the differentials of his early cars.
People were upset with the new 400s and 500s that came out later.

You've mentioned that previously, but the AMSOIL product lookup guide lists 75W-90 for that application.
What do you know that I don't know? Out with it Pablo!
