Hi All,
I am considering changing F and R differential fluid. I wonder if our LX570 come with slip differential? I am considering using mobil delvac synthetic gear oil 75w-90. I believe this one does not come with slip differential additive. Therefore I just want to make sure if our truck come with slip differential. Has anybody use this fluid before? Should I use Mobil 1 75w90 LS? Any input will be great!!

For all the fluids, I've always had Lexus dealership take care of it, so I may not be able to give the best advice on this. However, I looked up in the past threads and found something relevant to your question. It may help with your question:.

Here is the thread:

Hope this helps!

Front and rear diff's are NON-Limited Slip...Mobil 1 has a very long history of working well. No need for an LS type fluid and / or LS additive.


The thread you quoted is related to GX trucks, I'd call it non-relevant here.

Toyota recommends their 75W oil for the 200 Series transfer case. Given Toyota's pricing for the fluid, I elected to use Ravenol MTF-3 since it's been tested to and labeled as meeting Toyota's specifications. I bought it on Ravenol's website as it's not something you'll see at your local parts store.

Telephone calls to 6-7 regional Lexus dealers indicate they normally use Valvoline or Mobil 1 75W-90...great for the differentials but NOT for the transfer case. Some mention on Mud that 75-W90 may cause issues with the TC unlocking when it should be locked...something I've not experienced. Most attribute the issue to not using Low range enough if at all.

A how-to video on Mud is here...Series 200 differential and transfer case fluid changes. I use a compressed air powered filler that works perfectly...Easy to use fluid filling system

am i missing something here? changing diff fluids on a 2018 model year? this seems premature?

I am changing differentials and transfer case fluid for my 2017 Tundra at 30k. I was debating if I should change for my 2018 LX570 or should I wait till 30k. It has little over 8k now. A friend told me he did his at 7k after break in. I am still debating. May be it's premature. I should wait at least at 30k!

If it were used, I'd "baseline" it and change all fluids. Since you're the original owner, I'd suggest an oil change around 5-7K (I do my new ones at 1K). I'd say the rest of the drive train could wait until 30K or 60K, depending on how you use the truck. OT, if you believe the LX has what Toyota calls "lifetime transmission fluid", I'd be happy to sell you the Golden Gate bridge. I change the trans fluid every 30K as most of our driving is in the mountains and / or pulling a trailer. Driveshaft u-joint and sliding zerk fittings need lubrication at each oil change or sooner.

See above. When I did outside sales in the southwest, I could easily drive 30K a year in my company-provided (thank you, God) 4wd Chevy or GMC Suburban. If op drove for business like I did, I could see 30K if his '18 was sold in early 2017...my current LC is a '13 but door sticker shows it was made in 2/17.

I am not towing or anything as I have 2017 Toyota Tundra do towing etc. I will see how bad my Tundra fluid looks when I change at 30k. Only cost about $80 to change F/R differential and transfer case as I change them myself. Just drain and fill. They are fairly easy. I just like the idea change after break in!

I use 75w85 Redline synthetic. Not sure why everyone likes 75w90 since its clearly spec for 75w85 in any literature you can find for an LX.

hankinid

Probably because M1 and Valvoline synthetic are very readily available. They also had great reviews from users over the years. Zero functional difference between 75W-90 and 75W-85.

As I posted above, half a dozen Toyota, Lexus, and Toyota/Lexus dealers told me that they used either Mobil 1 or Valvoline and not Toyota fluids.

Use whatever you like.

yep. Same dealers that lose half the clips for my engine covers and screws for my skid plates every oil change. Which is why I only go to the dealer for the big stuff.
