I am sure this has been discussed before but I am stuffed if I could find it! Search retard

What sort and brands of oil does everyone use/recommend for the transmission and transfer case on the 5 speed patrols?

I have some 80/90 castrol stuff I was going to use for the front diff but am unsure if this is the best way to go.

I thought I read about some stuff that made shifting a bit nicer?

P.S it is a late 92 model ute. I am unsure what type of transfer it is?

Cheers

Castrol VMX 80
Penrite gearbox lite

I have read that the transfers in 92 models on should use Dexron, as they are chain driven, but some people disagree........would love to know myself too.

Manual transmission, the VMX 80 worked wonders in mine

STD Diffs - 80W90 or VMX80
LSD diffs - LSX90 limited slip oil
Lockers - 85W140 gaer oil

4 and 5 speed boxes - use 80W90 or VMX80.
Transfer in the Gear Driven transfers without rockcrawlers - same as gear box ( 80W90 or VMX80 )

If equiped with crawler gears a higher grade such as 85W140 i believe is the way to go

The chain driven transfer cases, you can either run the same gear oil as above, or u can run dextron 3, though im not sure which would be of the greater benefit, I personally would be very wary about running auto trans oil in a manuel box transfer.

my 2 cents, correct if wrong...

screwy

penrite say to use gearbox lite in both
i rang them re my 93 patrol which runs dextron in the transfer and they said it was ok to use the lite in the transfer plus if you get a leak between the 2 you wont get to driffrent oils mixing together

There you go then. LSD uses 85/140 lsd oil.

Locker uses any good 80w /90 or above if youve got some left.

I recently changed my oil from Penrite (pricey) to castrol EPX 85/140. Might be a little heavy over winter, but the rig does a lot of highway k's now (all day driving at 100 k's). One thing I noticed in the fuel economy was an increase, but unsure as to whether is due to using a different fuel supplier to a previous trip in March over the same road (Brisbane to Townsville). Ambient air temp was roughly the same.

Castrol epx is in transfer and tranny, 215,000km.
