Engine dipstick markings

[mole42]

My last 2000 mile round trip to France used about a pint of oil.
The previous one used about 4 pints.

I discovered the reason on my last rolling road session, the small puddle of oil beneath the car came from a faulty oil cooler take off plate which i have since replaced, or maybe towing the trailer tent helped this time?

I was using a pint of oil every trip - the oil thermostat was leaking. I've taken the engine out today and everything from the oil cooler position backwards is liberaly covered in oil. At least there's no rust....

"or maybe towing the trailer tent helped this time?" ...but only if it's performance was increased also, you tease...lol.

Richard / Mole 42 :- We used to joke, back in the day, that a Rover 800 was £800 quids worth of oil-leaks

On 4th June 2020 my oil was exactly at MIN and, to get it to MAX I added 400ml
On 12th December 2020 it was just slightly under MIN and, to get it to MAX I added 500ml

I must admit I'm not too impressed with the oil consumption, although the engine had still only done 4000km so maybe it's still running in?

Thanks Drew. That is just the information we needed.

So on my dispstick it is 17mm between marks, so around 25ml of oil equivalent to each mm on the dipstick. On my recent 1900 mile round-trip to the Lot, the level went down about 4mm, so that is about 100ml per 1900 miles. On the previous trip in 2019 and with a similar mileage, it used 4000 ml of oil (or 4 litres)! Only difference between the two trips is a baffle plate over the camshaft. Since my engine is 160K miles old with no re-bore, as Julian hinted, am I now replacing oil with petrol! Could the oil consumption be really that low? Is there a way to check for petrol in oil?

smell it Mike

Honestly fuel contaminated oil stinks. burns easily too.

If you want to go scientific this is a very useful process https://www.classic-oils.net/Insight...ysis-Programme
