Diesel Land Cruiser

[arnott1t]

Hi all, New here and looking for advice on an oil for my cruiser. It has a 4 litre diesel engine. 6 cylinder and is currently not tubo'd but will be. Its used for all kinds of things. Daily driving and long trips as well. I am up in Fort McMurray Alberta so temps go down to -50C sometimes. Its rare though. Easy -30C. I am running 15w40 Rowtella. So far it seems good. Also the engine is indirect injection so the oil gets awful sooty afte even a short time. I've its worse on IDI engines.

Thanks,

Watch for Canadian Tire to have sales, and you can get Rotella SB 0W-40 synthetic oil there in 4 liter jugs for crazy good prices. It has good cold specs, and is still 'old school' - SJ rated...not sure about the exact 'C' rating...

In the past I would have said XD-3 0W-40, but its been re-formulated to have a TBN of only 7.8, and the prices has gone, way, way up - not a bargain at all anymore.

Another good option is to go to a Petro Canada lube distributor, and get yourself a case of Duron E 0W-40. Awesome cold-weather numbers, and all PC oils are well-made.

Cool.. I'll look into the PC Oil. A plus is I work for them.....

Japanese indirect injected diesels typically spec a minimum of 3000ppm calcium.
Having said that, I've run Nissan 4.2 litre Turbo diesel on Delvac 1 successfully for the last five years with no adverse used oil analysis.

VERY good advice for the cruiser engine - they don't do as well in warm climes with the newer oils with low calcium levels - the replacement Magnesium decays at about the normal operating temps of the engine and you may get, as we did, - used oil analysis with elevated nitration, oxidation and suplhation results.

Theres an article round somewhere (I no longer have the link) that describes the difference between the older japanese designed diesels and the typical USA designed diesels that shows the differences in height down from the piston crown to the top rings on the different diesels and why the [censored] engines specify for the 3000+ ppm calcium levels.

The Delvac synthetic we ran in our 80 series factory turbo 4.2 (1HD-T engine) didn't show any elevated wear metals but did show elevated nitration, sulphation, oxidation levels - at 5000 km's - certainly couldn't get extended oil change intervals out of it and at the $20 a liter for 12 liters per oil change in the cruiser it is just too expensive to use with 5000 km changes!

Mobil couldn't seem to help us any and we did spend time communicating with their technical people.

You'll find if you search the virgin oil analysis results on the library here - that probably the pennzoil diesel longlife is one of the only oils now with high calcium levels and even THAT could be reformulated recently for all we know.

Whether the elevated temps/oxidation, nitration and sulphation is an issue in Canadas colder temps, I doubt, so you may not get the same issues as us downunder running the new synthetics in the older cruiser diesels in hot conditions.

Best of luck with it!

Cheers!

$20/litre is double what I've been paying

As I said above, the TD42T responded very well to D1.
Flywest, is your UOA still in the archive ?
Some of the traditional additive packages aren't coping in extreme use with ULSD. (for instance, BP's ULSD out of Brisbane and Perth is This is the feedback I've had from someone that sees multiple used oil analysis.

Currently running Penrite Diesel SP in the Patrol, a Group III and possibly ester Euro spec ACEA E4/E6/E7 10W-40 so the first UOA will be interesting.

Pretty sure the Penn LL has been reformulated here and is very similar to/same as one of the Rimula's.

Fuchs have a Japanese specific 3000+ppm Ca diesel oil here.

What sort of feedback did Mobil give ?
