OK thank you, I'm still new to the 2010+ Land cruiser family so I did not know.
Just a few years back, I have not heard of this Ravenol brand. Now it's spreading by word of mouth the fluid to use.
I did find there is a Redline MT-LV which is probably at least as good, that can be used in Toyota transfer cases.

It appears Toyota changed their manuals in around 2010 GX/LX/LC to state to use the 75W LF fluid, for the LC/LX they changed the transfercase part number, not sure about GX. I would think dealers just pump in their bulk oil on all 3 regardless.

 

I'd also recommend changing the front diff drain plug : https://www.kaon.com.au/front-diff-d...to-suit-toyota

 

Hi all, I just bought a beautiful 2016 GX460 luxury with 83k miles and wanted to do all the fluid changes and was looking for advice. here is the list of things i'll be using:

Front Differential: Valvoline 75w90 Full synthetic (bag not bottle)
Rear Differential: Valvoline 75w90 Full synthetic (bag not bottle)
Transfer Case: ???
Transmission: Valvoline MaxLife ATF

I'm looking to see if there were any other alternative i could get for the transfer case fluid besides the Toyota LF fluid and the Ravenol. Im looking for options where i can get the product from a store. If anyone has also has done a transmission filter change with drain and fill, please share me some of your experience or advice on doing it. thanks.

 

For the past 40k or so, I've been running Liqui Moly 75w MTF in my transfer case. Works great and is locally available thru Napa.

I've been using the pricey Toyota branded 75w oil, but only because I took advantage of a sale on online toyota parts, and stocked up. You will likely get a lot of opinions on this (as with any oil discussion!), but I imagine any synthetic 75w oil will work, incluing the 75-90 oil used in the diffs.

For transimmision oil changem check out the following thread and also the video from the

 

Ive been using the Ravenol 75W. Its a pain in the butt to get but is like 1/4 the cost of the liquid gold Toyota sells.

I've not seen anyone mention anything available over the counter but I am sure it would be ok. I am not sure what would make the Toyota stuff so special.

 

I use Ravenol 75W.

 

thanks for the replies and recommendations. I just wanted to see if anyone could also tell me if I am alright using Valvoline MaxLife in the tranny. I've used it in my old corolla and in a LS460 with no issues but just wanted to double check to see if it still alright with the GX460.

 

According to car care nut I'm 3 years pass due! I'm a 2014 and just turned 60k, I don't know any reputable shops I wish so going to lexus service is my only option to all this.

 

Are you expecting the engineering team at Lexus hangs out on the forum to answer questions?

If not, you're after opinions with a question like this and you will likely get many. Proceed as you wish with that information. If you're concerned, just look in the manual and use the fluid Lexus recommends.

 

I am not aware of anybody using MaxLife in the GX AT. If you want to take a risk and be the guinea pig go for it. Your AT won't blow up and only time will tell if it was ok to use it or not. I personally stick to factory specs including the 75w85 in the diffs and the Toyota fluid in the TC instead of pinching pennies. With DIY maintenance you save so much that paying for the proper fluid is a non-issues IMHO.

 

Changed the diffs and transfer case. Blauparts had a special with their kits so snagged a Diff and TC kit. Received 5 qts of 75w-85 and 2 qts of 75w in 3 days.



Here is what the built in flex tube looks like when fully pulled up that comes in every quart:


However, these did not work well for the diffs. And couldn’t get top off to put a pump on… For front Diff, opened 3 full bottles and was able to squeeze about half a bottle up from each below the fill. For rear, used extra tubing I had laying around to extend to an opening where the quart would fit. Sway bar in rear is in the way. TC no problem at all using the built in flex tubing.

Drove around a while to make sure no issues. IMO, I wouldn’t get the Diff quarts again, just based upon the struggles of fitting the quarts in tight areas and couldn’t get a pump on top.

 

Lots of debate on this one, but 75w-90 GL5 in the TC is perfectly good according to Toyota.

Don’t believe me? The part number for the transfer case on all GX460s is the same as the full-time 4wd V8 4Runners. Those 4Runners spec’d 75w-90 GL5 in both diffs and the TC. No need to lose sleep about the special 75w unless you just feel like it.

In fact, even the part time transfer cases in the 4Runner are the same from 2003-2024. A lot of the confusion seems to come from the Tacomas which did get a new TC design for the 2016 redesign.

 

After reading through a thousand threads I decided to run Amsoil 75w90 in all three... diffs and transfer case. Even switched to 5w30 in the engine instead of that 0w20 spring water. It's been a long, hot summer of both highway miles and stop and go city traffic and I don't think I've noticed even a .xx reduction in fuel economy. I still might go Ravenol 75W for my next transfer case oil change because, well, the fear is out there....but I feel like everything's just fine with what I'm running.

 

Anyone notice similar debris in the 22-23 rear diff?
