WHEN OILS AIN'T OILS

kevin,

Any of the well known brands of oil are good. They all probably come from the same refinery. The only difference is the additives that are used.

I use Shell Riumlar X, it is a good oils and can be purchased just about any where in Australia. I try to avoid mixing different brands of oil.

When I buy a new car ( second hand) I always change them to HPR Diesel.

It works for me and my cars work hard.

Cheers Steve.

Since we're on this topic, I would invite comments:
I have always used a proper diesel oil in the 4.2TD diesel Patrol and the earilier 4.2 Mav.
I have seen plenty of multi-purpose oils which meet both S and C specs ("suitable for petrol and light-duty diesel engines"), but have avoided them, preferring to stick with the more expensive dedicated C-specced diesel oil. I am currently using Caltex CXJ for Japanese diesels.
Am I right to do so, or am I being over-cautious?
I suspect that a lot of service centres use the multi-purpose oil (they only have to carry one type of oil).

Kevin,
Wasn't going to bite on this one but I will a little bit. Using a specific diesel engine oil is better used in older vehicles, the specific diesel oil has a bit more detergent to wash away the inherant cr@p you get in older diesel engines. Saying that, now that the diesel spec is now heading to 50 ppm sulphur and lower the diesel burns cleaner so you don't get as much contamiantion from the blow by because of the higher compression ratios of diesels. I use a full synthetic oil myself which is not cheap but neither is a new engine, so $90 every 10k for peace of mind is OK. I have one of the infamous 3.0 TD series one Patrols so I need all the help I can get, so far so good "touch wood". The comment about the same refinery and the addatives is true, anywhere in the world oil is refined the same way with the same end product it's all the blending afterwards that makes the oil good, better or the best.
I work at an oil refinery and have done for longer than I care to remember, not that this makes me right but I have an idea.
Other opinions may vary this is mine, hope some of this might help.

Kevin,
If you want a Ci-4 diesel oil at a good price, I've been using Gulf Western TopDog 15W40. Get it in 20 litre drums from Adelaide Truck and 4wd Spares on Regency Rd. Last time I bought it, it was $72 but that was early 2007.

If it's a second hand vehicle, I try to use what the previous owner was using, otherwise Penrite HPR.

Hello Kev, I have a great mate inAdelaide who has several sealed containers of diesel oil. He is a very fastidious bloke, so it would have to be First Class oil.
He sold his vehicle, but still has that oil supply in his garage.

Give me a call 0411664127 and I'll pass on his info if your interested.

Cheers,
regards Dennis
