Thanks

Delo's site mentions the multigrade is for Pre 2007 vehicles http://www.deloperformance.com/products ... -oils.aspx
Is this correct? Should i use the Delo 400 LE SAE 15W-40

My father in law is a diesel mechanic and they use delo 400 on all their site vehicles. I've asked him to talk to their oil guy from Caltex to see what he recommends for the triton.

My guess would be the the LE SAE one is designed for use with engines with a dpf which our vehicles don't have.
Both oils seem to claim they're suitable for mixed fleet use which probably means you'd be fine with either - but don't take my word for it since I've not used their oil.
The frustrating thing is that the caltex website recommends havoline 5w-30 and then doesn't list your other options like a lot of the other sites do.

The Delo LE is also for more moden engines, but a grade lower at SM, probaly as it is not synthic based. The std Delo 400 is for older pre low sulpher engines.
The Fleetmaster Hitech oil is 2 grades lower than the the top quality oils we have today, ie being an SL grade - hence why its probably cheap.

While correct for petrol engines this may be a little misleading for diesel engines. The API service classifications SL, SM and SN refer to petrol engines, not diesel, The applicable diesel engine service classifications run in a series starting with "C", so for example CH, CI, CJ. There are intermediate classifications such as CI-4 and CI-4 PLUS.
Because oils are formulated for specific applications it is quite common to find that an oil which meets the highest or latest specification for petrol engines may not meet the highest specification for diesels. Going to a later specification for oil may not necessarily be the best thing to do for your engine which may be better suited to an earlier specification.
Always use the Mitsubishi recommendations in your handbook as the starting point when choosing an oil and, if in doubt, discuss with the oil company of your choice.

NowForThe5th wrote:Pretty much right there Alex. The API and APEA are not oil companies, though, they're independent bodies that set the standards. Some manufacturers also set standards and you'll see the Caterpillar and Detroit Diesel standards most often, but also others like Ford, GM, Volvo, etc.
When I have a look at my handbook the interesting thing is that these engines don't actually call for a particularly high or recent standard. API CD is what is specified and that is actually obsolete. What that means is that almost any diesel oil that you can buy today will meet the standard required to maintain your warranty. Some oils, however, may do the job a little better and you need to weigh up whether the improvements in oil performance are worth the additional cost. For example, full synthetics are nice but not necessary if you're doing intermediate oil changes or not operating in really severe conditions (probably 98% of us).
Looking at those Caltex oils it seems to me that the Delo 400 LE (CJ-4) is designed for vehicles with DPF (which we don't have) so I think I'd be looking at the Delo 400 Multigrade (CI-4) instead, which is aimed more at engines with EGR and/or SCR systems.Cowboy Dave wrote:So is CJ the highest grade out of that list?
Yes, CJ-4 is the latest standard but is formulated more for low sulphur fuels and can actually work against you when you're using the relatively high sulphur fuels that we see. The CI-4 standard is better suited to high sulphur fuels.

Don't use it!!!!
