$80/liter transfer case oil

Did anyone do a uoa



Did anyone do uoa

I did, but I need to compare it with the Toyota 75w LF. So it going to be a while before I know.

I will say, that with some Amsoil Severe Gear 75-110, there may have been some slight increase in wear. But I’m not jumping to conclusions until I get some miles on the 75w that’s in my T-case now.

The ravenol gear oil might be the best alternative.

What is interesting in my area Lexus dealerships don’t use the Toyota 75w for lx. One uses Kendell which is made by Phillips 66.

so transfercase/differential oils are one and the same as long as they are rated GL-5?

For 2008-early 2010, yes.

For mid 2010- current, not really.

Does it matter? That’s for you to decide. Our engines call for 0w-20 (5w-20 was an option for the first 4 years also). Can you run 5w-40. Yeah, and it will last for 100k, but will it be better? Probably not.

The mid 2010- current manual doesn’t call for a GL-5 in the transfer case. Which is a tell tale sigh that it doesn’t want the super slipperiness properties of a GL-5.

This is the same as when transmissions slowly transitioned from wanting a differential type gear lube to their own not so slippery gear lube because of more syncros and brass internals.

So you you run a GL-5 gear lube and be fine. Probably. We’ll all find out eventually. Almost everyone (including dealer serviced) 200s/tundra/3rd gen Tacoma is just putting 75-90 in their t-case and not caring too much. I just can’t do that personally though.

Another reason I’m doing my differential fluid changes at 30,000 miles and waiting till 60,000 to do the transfer case transfer case fluid doesn’t get very dirty, so why not keep the OEM transfer case fluid in until the recommended Lexus interval?

 

[SWUtah]

Sounds based on this thread that it’s pretty obvious that Lexus when I change my transfer class fluid will put whatever they put in and it won’t be the expensive stuff that’s a reason to keep it in until 60,000 miles versus get rid of it at 31 it doesn’t wear much and too I’m probably not to go to the same quality you have lube oil

After reading a few forums, i have purchased the toyota 75 w transfer case oil. No need to risk damage.

OK guys if I’m driving a mall cruiser LX 570 at what mileage do you think I should change the transfer case fluid since it is such high dollar and I don’t know I’m going to get the right stuff no towing no Offroad just driving around in Florida

My lx 2013 with 87000 miles. I purchased a couple of months ago. Previous owner dealer serviced since it is not on the lexus owners history for having the transfer case and differentials fluid exchanged. I assume the service interval is 100,000 miles. I could not find in the owner's manual the service history for non towers/non off roaders.

@SWUtah The manual says to inspect it every 30k miles. Here's the info from the 30k mark (looks the same at 60k, 90k, ad 120k). There's no specific replacement interval listed.

If you don't tow and don't run in 4Lo or lock your center diff very often, you could probably run it for the life of the vehicle, or damn close. Personally I'd pick an interval (60k, 90k, 120k, etc) that you feel comfortable with and stick with that. I'm not sure your mileage but if you're closing in on 90k or 120k and planning to keep the truck for a long time, I would spend the $500-600 and do the front and rear diffs, transfer case, and a full 12-quart AT fluid exchange. If you're at 30k you can easily wait. Honestly a full transmission flush is IMO more valuable than the diff and transfer case since just lots of stop-and-go driving in the florida summer can wear the AT fluid down over time.

BTW up to you but many of us use the same diff gear oil in our transfer cases. There's a thread on it around here but there's not a huge difference between them, except the transfer case has a "low friction" modifier that's supposed to help with gas mileage, whereas the diff fluid is a "heavy duty" gear oil. (FWIW I noticed no difference in mileage when I did my exchange at 60k).

I totally agree about your comment about the transmission fluid exchange. I picked up the lx from Florida on a Saturday. First thing, Monday morning the transmission fluid was being exchanged. Best money spent on maintenance item.

 

[SWUtah]

I’ll do them all between 55k and 65k so my wife doesn’t lose her mind about the cost

I'm getting gaskets and fluids for the driveline with a plan to change 'em on Labor Day Weekend, or whenever it cools down here.

With that and this thread in mind, I called the two local Boise Toyota stores (one also sells Lexus) and spoke to both service managers as to $70/qt.-wtf trans case fluid.

Toyota advised they use Valvoline 75W-90 unless customer insists on Toyota tc fluid. He also said he's seen zero issues with transfer cases on any 200 trucks they service.

The Toyota / Lexus calls (2) were interesting. I'd called earlier today and left a msg for a service writer to call me back...after 2 hours, I called and spoke with service manager. She advised me that they use only Toyota 75W period. She also said I could run into shifting problems if I used anything else...also said she had not seen or heard of any shifting problems.

As I said g'by to her, phone rang with service writer returning my call. He told me that they did not use Toyota's oil, but good ol' Valvoline 75W-90. He also verified they'd never seen a 200 series with trans case issues other than rock damage.

I'm simply gonna go with Rexoil at $16 a quart on Amazon.

Sounds about right. Very few people really care this deeply and like I mentioned earlier, you can probably run whatever you want and the drivetrain will still last the life of the average user.

Hell I just dumped 75w-110 out of mine. That said, I did start to have a bit of center diff lock issues. Went to 75w and now it’s gone. I’ve got the UOA to compare it, but I’m waiting till I be a base line.

I will say, I’m not really assigned with just one analysis of gear oil. I think there really is something in there.

Aside from that, we need to remember that bearings wear more with thicker oil. And with a chain drive t-case, we’re not gaining anything from a thicker oil. Something to think about.

What are the thoughts around the earlier 200s (like 08 and in my case 09) using straight 75w too? I'm sure there will never be a TSB, but as one of those that sees occasionally 4Lo shifting issues I wonder if I might want to try 75w in the transfer case.

Right now I have a couple quarts of Amsoil 75w-90 standing by, just hadn't gotten to the transfer case fluid exchange.

$30 for a couple quarts 75w Ravenol is no big deal if there would be benefit to reliability.

Your t-case requires 75-90, so stick with that.

This whole “maybe we should follow the Asians in white lab coats” talk is for the part number change and the requirement switch to a strait 75w sometime in mid 2010.

You can try but I doubt it will matter. My 2013 had the factory 75W "LF" fluid in it and it had the same CDL issues everyone else does. I'm running the Toyota-recommended front/rear diff oil in my t-case now and it's no different.

Have you tested it or is this just off of feel?

I never had CDL issues with the 75w. Went to a 75-110, issues. Especially below 60°F outside. When back to 75w, no issues. Coincidence, maybe, but that’s why we analysis stuff right?

In case anyone is wondering why I did 75-110. It’s becuase I don’t have factory diff gears or axle bearings. So my requirements changed. And it would of been nice to have one less fluid to source, but oh well.

I am about to take on this project myself. I recently took my 200 in to get a 55K service and the advisor came back to me and tried to sell me $800 of fuel injector cleaner, power steering flush, and HVAC mold preventative. I told them i just wanted to go by what's in the manual. He proceeded to tell me the dealer manual was different than what is in the owners manual. I almost lost my mind on the guy. They could have upcharged me on the Diff fluid changes and i probably would have been ok (since they missed it at the 50K service too). Now i dont trust them so i am going to do it on my own. I will still take it for oil and filter change since they only charge $80 and rotate the tires while they have it.

Has anyone seen that Mobil 1 and Castrol both make a 75W?

It appears to only be for the EU markets though....
