Front & Real Differential Fluids

[Ldub]

Bart,
They use Amsoil exclusively and I recently had them replace my front and rear diff. fluid, transmission fluid, and transfer case fluid with the stuff. Apparently Amsoil has been "synthetic" since like 1920 (it's a corn based lubricant) and it's supposed to last forever. Well, not really, but Amsoil states that the transmission fluid is good for 500,000 miles. They also state that their oil is good for 25,000 miles between changes. There are some additives that you have to pour in every now and then, but that's about it. I didn't do the oil because I just don't trust a 25,000 mile oil yet.

Anyway, all of that is to say that when they where changing the fluids out they said that the old stuff was in fantastic shape and could have gone another 70,000 miles (the VX just turned 70k after Moab). To my knowledge those fluids where never changed by the previous owner so it seems like Isuzu put some good stuff in there to begin with.

I'm completely in agreementalness with Mark...I have run nothing but Amsoil in every orfice since about 20k, & I think my oil usage during the Moab excursion (1 qt. in almost 2500 mi.) speaks for itself.

It's more expen$ive to use @ regular change intervals, & there's no WAY I'd go 25k on an oil change...but there's nothing too good for Suzy.

IMO, it's the "good stuff".

If you do any water crossings you will want to change your diff fluid more often as water can get in through the breathers (unless you have extended them to higher ground).

Kenny,
Thank you for posting those!
I never had a manual, and those specs will also (hopefully) help sell my '99.
Thanks again!

Yes, thanks Kenny. I know I have all this info in the manual, but you just made it nice and easy. I think I am going to go buy some fluids today and try to get the diffs dones this weekend.

I notice in the above post #17, the timing belt change interval is 100,000 miles. Would that also apply to the JDM 3.2L engine??
I believe our 3.2L engines are dual overhead cams - aren't they??
The single overhead cam 3.2L engine used in most Rodeos and Jackeroos in Australia requires changing at 100,000 KM (62,000miles).

I have just ticked over 104,000 KM and want to be safe.

Appreciate your input guys.
