Is there a way to test for diesel in the oil?
The other day I noticed that the dipstick was reading high - wasn't sure if it was my fault or not so I did a quick drain and refill - the oil in the bucket looked, well just like black engine oil. No film floating on it etc.
When I refilled it with new oil, I left it between Low and High. Then I towed the caravan down to Cornwall and worked it hard (21mpg) and went to check the oil this morning for the return journey and it was up to the High level. Now I am convinced I have leaking O rings.
Drove the caravan back home and went to check the oil level again fearing the worst and it's back to between Low and High (after about an hour after stopping).
I am so confused - don't want to change the O rings unless I need to - so hoping there is a way to detect if diesel is getting into the oil.
On all occasions then truck appeared to be on the flat - certainly not on a slope.
