Thanks for that. This is the first time I've seen a logical explanation for the issue that we have been having with the diesel, and bought to us by a V8 petrol owner.

Swampy, I got a leg on each side of the fence.
I do still have my old WJ diesel!

Re: Diesel Dip Stick Reading ?

Standard dip-stick practice on any machine is to pull it out, wipe it, put it in, leave it a second or two, take it out and take a reading.

That sounds like foreplay.

And that would work well if the 3.0l JGC arrangement didn't drag oil up the dipstick tube to foul the reading when re-inserting the dipstick.

For consistant readings, do as described previously in this thread; lift the dipstick only 20mm to crack the seal and release the air lock, reinsert then withdraw fully to read.

Re: Diesel Dip Stick Reading ?

Okay, I need help. I have about 15k on my 2014 GC CRD. I've changed the oil twice and don't recall having any trouble reading the oil level on the dipstick before. However, I have been thinking about going to Baja recently and when I checked the oil while the engine was cold it looked low, so I added 500 ml. I tried checking the oil after that but I couldn't get a clean reading. A few days later I checked the oil level again when the engine was cold and it still seemed low, so I added another 500 ml. Once again, i couldn't get a "clean" reading on subsequent attempts. The same thing happened a third time, but I decided something must be wrong with my technique and found this thread.

I removed 1000 mm of oil, under the assumption that I had overfilled the engine. I've then tried the techique recommended here (pull out the dipstick 20 mm, then reinsert before removing and reading the level) three different times: 1) after 15 minutes, 2) after the engine had cooled to 100 degree F, and 3) in the morning when the endgine was cold, all with essentially the same result: the dipstick wasn't clean and was impossible to read.

Has anyone else had similar difficulties? I'll probably change the oil tomorrow so that I can be sure I have the right amount in the engine, but I'd really like to be able to read the dipstick!

Thank

I'm glad this old thread got revived, following this process is the first time I've managed to get a good oil reading. Previously I'd remove it fully, stick it back in and pull it back out, getting oil dragged all over the reading.

Re: Diesel Dip Stick Reading ?

Thanks, but to be clear, that IS the method i've tried and I still can't get clean readings. I'm really at a loss...

Thanks

Clean your dipstick with some degreaser.
If it has any type of wax contaminant on the stick the oil will not stick to it.

(some tissues have oil and waxes to make them smooth on your nose)

Me too.
I've been getting inconsistent readings and at last have an explanation, and a solution which seems to work.

Now I know I'm not going mad, - well not quickly anyway.

Thanks.
