Thread: Oil Recommendation for LT95 4 speed box and Isuzu 4bd1

No, VMX-M is a mineral oil primarily for Mitsubishi gearboxes, Syntrans 75W-85 says Syntrans 75W-85 on the bottle.
It wwill also say that it's a full synthetic manual gearbox fluid that is Castrol's 'problem solver' manual trans fluid, as well as having Volvo trucks approval.
There are four flavours of Syntrans, this is the one you want, I think Syntrans-M might be too thick, and Syntrans Max and Syntrans-B are definitely too thin.

Syntrax is Syntrax 75w-90

Thanks Rick, that was close. I would have bought the wrong one. They didn't have Syntrans on the shelf then... So went without. I'll find it elsewhere.

I did pickup 20L of Castrol GTX diesel 15W-40 for $100. Seems like a good deal and covers me for the next 2 oil changes.

Syntrax 75w- 90 suitable for Isuzu LR power steering system??
Thanks

No, it should be ATF, shouldn't it ?

The heaviest hydraulic/gear fluid I'd use would be a 70W-80, and a light one at that.

I was reading my county book just this morning. It recommends ATF IID.

According to the receipt in my pocket, 4L of Castrol ATF dex II is $30. I'm using it for my Isuzu power steering.

If anyone wants reduced noise and wear in their steering system, use a tractor/heavy machinery hydraulic fluid or a low viscosity tractor UTTO fluid if you can pinch some from a farmer, eg. Mobilfluid 424, Fuchs Titan UTTO 10W, etc

Much higher levels of anti-wear and extreme pressure additives compared to most ATF's with anti-squark additives so no noises/groans etc from the steering at full lock.

Having said that, I've used Castrol Transmax Z ATF in the Patrol PAS since it came out of warranty, it's now past 420,000km and I've never needed to adjust the steering box, nor has it ever developed a single leak or even a smudge of oil anywhere.

As I will be running power steering and a PTO driven hydraulic winch from a
common reservoir was just trying to minimise oils carried
I thought maybe I could get away with one oil in Lt230 with with tbd center diff
MXA 5R gear box . Rear 9" detroit locker diff and wheel bearings
Front 9" trutrac swivel housings and wheel bearings and Power steering winch
hydraulics as well but not to be

Thanks AM
