What fluids are you using in your Monty?

Hello all,

I posted this over on the wire as well, and I was just curious as to what brand of motor oil, and filter, and fluids everyone was using in their GEN1? I have the 2.6L and I am looking for a brand to use exclusively. I am doing a serious overhaul of my Raider, and just want to see what has worked, or not worked for people. I never really thought to much about oil until joining bobistheoilguy.com. But not to many people have Montero/Raiders on there.

Happy trails to all

Really anything from decent brand name would work if correct weight oil is used during appropriate service intervals. For piece of mind I use Mobil 1. It's overkill. But I like to change it myself, take a look around, etc

Don't piss down my back and tell me it's raining.
I've been running the following in my Gen III for ten years:

Engine: Castrol GTX and Wix filter
Differentials: Amsoil 80W-90 Gear Lube
Transfer Case: Amsoil Severe Gear 75W-90
Transmission: MM ATF

I do have Amsoil in the differentials, and Pennzoil Synchromesh in my manual trans. However, the Synchromesh is about to come out, and Redline MT90 is about to go in.

Redline MT90 is a great product for the manuel box...I ran that for years in my Toyota and never had any issues.

Has the Castrol kept your engine clean? The previous owner of mine ran Royal Purple. The thing is spotless inside..

I've never torn into the engine so I really can't say how clean the inside of the engine is...
From what one can see with a flash light down the oil port it is very clean. (Changing the oil on a regular basis is something I've always believed in.)
If the rig has a good record running Royal Purple, why are you looking at switching oils?

Royal Purple is just really expensive! I am trying to find something that is just as good, but cheaper. I put Chevron Supreme 5w30 in for now, and it seems good. I want to stick with a synthetic though since the head was rebuilt. I am searching for oils people have used, and had good luck with...

Royal Purple is API rated now. Their HPS stuff is not though. That is the Hi-Performance Street oil. It is loaded with ZDDP, and some other stuff.

My understanding is their marketing says they exceed the specifications however there is no API logo on the bottles which indicate they're not API approved/certified. Do you have an API certification logo on your bottles or RP? They may have begun having their oils certified since I learned that.
Should look something like the below.

When I checked last it had the Starburst on the front and all. I will double check. When I called them about a week ago, they stated, that it met the new criteria. The HPS version is the only one that does not still.
