Morry,
it might depend which year 6.5 it is, turboed/natural or electronic.

When I installed mine I was told to run only Delo 500 15w40. (1994 engine)

Roachie maybe able to tell you what he runs in his.

Les Addison on the 4wd monthly forum is a wealth of knowledge on these engines, what he doesn't know about them isn't worth knowing.

Have a good one.

Morry,
I had to use delo 400 gold in the engine as delo 500 silver wasn't available.
My oil comnsumption went up, as soon as I changed back the consumption went back to normal. Around .5l to 5000k.

I would get some good advise on the use of the 5w40 synthetic as the 5 seems to low for a hot climate.

I also have been adding a mix of 200parts diesel to 1 part 2 stroke oil to the fuel tanks, this is to mask the problem of low sulpher diesel, the engine seems to run smoother or my imagination thinks it does.

Have a good one

G'day lads,

I was running Amsoil 100% synthetic 5w30. It's about as thick as full cream milk!!!!!. I have been using a fair bit of oil (about 1 litre every 2000klm or so) and have been adding Delo 400 as a top up. I reckon I've added about 5 litres along the way, so can't be sure what the actual consistency (or "w" rating) of the oil is at the moment. I have a Amsoil bypass filtration system, so don't plan on actually dumping/changing my oil, but I'm due to send another sample off to Castrol for analysis pretty soon. I do this at arouynd 15,000klm intervals.

The post on 4WD Action forum....here's the link....6.5 Chev link is a wealth of knowledge. I agree that a 5 weight oil in the Chev is probably way too light.....15 is better.....I'm wondering if a 20w might be even more appropriate?

Simple question, and i know i wont get a simple awnser.

Why do you need to run synthetic oil. ??

Really expensive, and not sure of the advantages.

I know the advantages in transmissions, as in better and smoother selection.

I run the latest oils in old tecknoledgy motors TD42'. valvoline oil, recommended by Nissan. 370,000ks no oil consumption 5000k service, super charged, done all the hard dusty pull heavy camper, desert trips. Buy 20 litre drums around the $120 mark.

I put the Chev motor as old knowledge

hi col
morry here all answers are simple . we dropped in around may had drinks remember I had the 2.8 gu . about the oil just trying to silence the chev which I put in plus new manual gbox and HSpeed difs. Until it warms up the chev is noisier than the 4.2 nissan. hoping the oil might quieten it up a bit, and also 65 kilos heavier than 2.8 imho .
but the engine is cheaper to run compared to the 2.8 it works for me . and i have already done 11000ks with this motor . those fires at tolgo were they around your place?? give our regards to linda

Hi Morry,

Yer they are a noisy motor, thats what put me off fitting one after going for a ride in one. Hope the oil helps.
No the fires wherent close but we could see them on the other side of the mountains.
Having to deal with the rains now, have gone from a dust bowl to lush green, have had constant rain for the last 5 days, but no bodys complaining yet. You cant even tell where all the fires had been, everything grows so fast.
Doesnt help when you go to use whipper snipper and it doesnt start after sitting for so long.
Im glad to hear you now have a reliable vehicle after all your past dramas.

Cheers Col
