As above really, my navara seems to have started generating its own engine oil,
It had a service a couple of months ago at which time the correct amount of oil was put in, on Monday we took six litres of 'oil' out of the engine to get it back down to the correct level.
It's not water in the oil.
Can diesel find its way into the sump?
Has anyone had this problem?

Yes, we will be doing that, not running it till we work out what's happening.

It's a case of what else can it be?, six litres is too much for it to be a slight overfill..

No idea about Nissan, but Fiat engines tend to leak a bit of diesel into the sump during the regeneration of the particulate filter. That's why after a fixed number of cycles the oil change light comes on.
Not 6 liters in 2 month though...

The DPF warning light has come on, that's what made me have a look round. We don't do a lot of mileage, and I admit I hadn't checked the oil level since the service

Failing Regen's add oil to the sump. Drive the truck on some longer runs so it can clean the filter before it'd blocked and a dealer forced Regen is your only option.

When you say failing regen's add oil, where does the oil come from?

It would be pushing it to dump six litres in a couple of months / 1500 miles?

That's the question I hope will get answered.
When she's running, she seems fine, not smokey, not short of power most of the time, I did have to move into the slow lane on the M6 the other night when power seemed to drop off, but it corrected itself and that, along with the DPF light is what triggered the investigation.
At the time of loss of speed I couldn't decide if it was engine or transmission (it's an auto) problem, which has just made me think, is there any way transmission lube can get into the sump?

The only lit light on the dash is the DPF orange light, never seen any other lights light up during use.

Pull the DPF out anyway.
