Oil level rising

[Gldo]

Oil level is rising.

No it isn't.

Saying it as I see it Glyn, I feel like the vet trying to diagnose what is wrong with the dog.

We really do strive to be helpful, and unlike solicitors, we don’t charge by the word - we don’t charge at all, so how about sitting down for 15 mins and compiling a bit of a story about the problem-?

A3 2006 1.9tdi, changed oil and filters a month ago levels were correct,one month on oil level above max, no coolant loss or cream in filler cap,could it be diesel contamination. Bxe engine with approx 90,000 miles no other problems,runs well.

That's better. Having some explanatory detail gives us a chance to provide some assistance.

When you filled with oil did add the recommended measured quantity, or did you simply fill to the line on the dip stick?

[Gldo]

Filled to the line on the dipstick.

Fair do’s as we say in these parts Glyn, you seem to be a man of few words, and the details are dribbling through like a dripping tap! 
Questions:- 

When ‘filled to the mark’ during the oil change, how soon after was that level confirmed to be at the mark?

How much is it now above the mark? 

[Gldo]

Checked the level approx 30 minutes after filling, level now is about 1/4 inch above the mark. Don’t know what else to say about oil level.Not mechanically minded as you can tell.

Thanks Glyn,

I always re- check the oil level on level ground, the morning after the oil is changed. 
It’s surprising how long it takes for all (in caps) the added oil to get down to the sump. 
Too late now, but…….

If it were mine:-

(1) Check the oil level (on level ground) before start up tomorrow morning. 
(2) If it is above the line, get an accurate mm rule and measure exactly how much above the line it actually is.

(3) Check again after 300 miles or 3 weeks and see how much it has increased. 
If it has then proved to have risen, it could be due to oil dilution with diesel. 
Please let us know how you get on Glyn.

Regards,

Gareth.
