Looks like we're not the only ones with gripes...

This one is strange ...

http://smh.drive.com.au/motor-news/b...821-24k6w.html

For oil level to be rising on its own, doesnt that necessarily mean that fuel, coolant or other fluid is getting in to the oil?

Also the comment about being perfectly normal for a DPF equipped vehicle is a bit weird.

Re: Looks like we're not the only ones with gripes...

You'd think someone has done the science on the diluted oil to find out what it is.

Anyhow, good on the Mazda owners, at least they're checking their dipsticks!

Looks like "People Power" is being heard via the forums!

“It’s not a widespread issue that we should be acknowledging,” Maciver says. “There’s a small number of people who’ve voiced concerns on forums and with dealers with this and we’re absolutely dealing with this as we normally do under a new-vehicle warranty.”

Re: Looks like we're not the only ones with gripes...

I think that you will find it is diesel dilution. On some diesels with a DPF the engine management system injects more diesel into the engine to increase the exhaust gas temperatures for the DPF for burn off. Unfortunately for those who only ever do short runs from a cold start, the generated heat and burn off cycle never gets completed properly so the vehicle is constantly trying to achieve burn off and the extra diesel finds its way into the sump.

Doesn't seem to be a Jeep issue (or haven't heard of it) so I suspect that Jeep may have a more sophisticated arrangment with their DPF.

Re: Looks like we're not the only ones with gripes...

This is my first diesel (car) and that's something i didn't know before. Thanks for explaining that in layman's terms Swampy!

Re: Looks like we're not the only ones with gripes...

hahah coming out of a diesel outback 2010 dilution is exactly what it is. I never had any trouble with mine but the forums were full of dpf issues mostly when filled up with soot> this was directly related to short trips compounded by incomplete regen cycles. So the oil gets full of diesel. check out aussubaru forum and dpf issues if ur bored theres hundreds of posts. The new dpfs can be painful, trick is to run the engine as hard as you can given the circumstances if its not a long run. That way the dpf stays hot and clean, reduces the regen cycles where it blows extra fuel into the mix which is a vicious circle.

I also used a fuel additive lucas i think which reduces soot and keeps the injectors clean. But drive em hard.

Re: Looks like we're not the only ones with gripes...

I have checked my oil level yesterday and after 5,000km it is spot on the mark. My car is only used for short trips, so I am not sure if this will be a problem with the CRD JGC.
From what I have been told our DFP is close tot he Turbo, so does not require the DFP regen of the older DFP systems.
