Hi Big_Nige,

I have a 3.1td also & I use 10/40 turbo oil and it works just fine. The oil is designed to cope with temperatures way below zero and way above. That external starting temps obviously the oil thins as it gets warmer hence the drop in oil pressure after the engine is warm.

10/40 turbo will be fine

Hope it helps :D

Because of the extreme temps in the turbo, I'd be tempted to run some kind of Synthetic. 10w40 should be a good weight though. Does your owners manual say what is recommended? Also be sure to let the turbo cool down if you've been driving hard and park it.

I'm using a decent quality semi-synthetic 10/w40. I intend to change oil & filter every 3000 miles

Also, I dontknow if you can get it there, but I have always run Shell Rotella, its great in turbo diesels, and I have never had a problem with it.

Just a sugestion..

I was just at the Canadian Tire store and saw 5w-50 oil. Sounds like it covers all the bases. Good for cold starts and can handle high temps, resisting oil burning. I'm still under warranty so I'm sticking to 5w-30 until its over. I saw a auto repair show on tv and the local expert claimed that with all the engines he has repaired the ones that used 10w-30 had less wear than the ones that used 5w-30. My mechanic use to put 10w-30 oil in my mini-van in the spring and summer and in the fall and winter he would put in 5w-30.

Someone just posted a message on one of the Isuzu boards that he eliminated his oil burning problem by using Quaker State high mileage 10w-40 oil. He claimed he used half a quart in 3000 miles.
