Engine Oil BRand & Type

Hi Not truxter, but i can comment that this oil is used in my friends 1hdt 91 cruiser, and its the only one that doesnt get used by the motor. All others need to be topped up after a few thousand kms. Oil pressure is better aswell when the motor is hot.

I changed to RX last oil change, and did a trip to bleep ney and back so far, seems good.

Was using Rimula X and would have this time but they didnt have it in 20 ltr drums.

Will: I've got the HZ motor !!! bog standard diesel with a water separator 'in line' filter ...!!

Wil why not go and ask the technically qualified brains or read the archives on the Overlander Forum

Hi Andrew, In regards oil pressure on 1HZ, I have 97 troopie with 260k's and the oil pressure at idle when warm looked a little low to me (going by the guage). Normally sits fairly low on the guage at idle. I was concerned about it and got it checked by a decent diesel mechanic, he said it was a bit lower than spec's but ok. I have since seen a mates 1hz same year as mine with near 300k's his was the same. Is this fairly common? I use castrol GTD oil and dont have to add oil between changes. My mate used valvoline in his 1hz and it used plenty, seemed ok with the castrol? Cheers, Peter.

I've always been of the opinion that the brand of oil doesn't matter (as long as it a repreable brand) as long as you don't go changing brands constantly. I've stuck to this rule of thumb for the past 20 odd years and it has served me well with excellent mileage out of my vehicles. What I mean by that is when I've sold the cars there was still no sign of the motors burning oil.
Have I been led up the garden path for all these years in that you can change brands without reducing engine longitivity. I thought I'd ask this because I see a lot of people asking about different oils they want to put into their vehicles.

I think stick to the oil rating that is in the manual. If it says use CF, use CF even though this is not the latest rating. Later oil ratings in part have evolved to meet environmental criteria and so some of the additives that help to reduce wear (such as phosphorous) have been ruduced because of environmental concerns. Search the net and there are some comparative tests available including I think some links in past posts on this forum.

I spent alot of time trying to research why my nissan manual says top never use CG4 adn all I found out is latest rating specs in not the always the best.

I use Pennzoil, brilliant sh*t. Take prices of all oils and go the most expensive. Not saying for once that Pennzoil is the most expensive but it's up there with em.Love the bush.
