Oil change 75 Diesel

[JMW]

Hi,

Changed the oil through the sump, and replaced the filter as usual, do it every year, once the new oil went in it was very dark straight away, it almost looked like I hadn’t changed it.

I’m not sure how much oil still sits in the system when doing an oil change through the sump, is there any other way to do it to get more of the old oil out? Vacuum it out through the dipstick?

Thank you

JMW

I wouldn't worry about it. It's happened to every diesel I've ever owned.

It's just the way it is.

By the way, on this car I do vacuum it out, it's still the same.

Simply check the amount you got out against the dry capacity.--That will tell you how much old oil remained in the engine.---( Starting with the dipstick level at full both before and after. )

You need to worry if it didn't turn black.

The oil would not be doing it's job at removing the high carbon contents, produced with diesel engines, if that didn't happen.

Does more oil drain out if the car is on the flat or up on ramps?

Best to have the car low and raised a little at the passenger side so the oil drains towards the sump plug.

Doesn't really matter if you can do it like this as mine is on 264k doing normal oil changes every 8 to 10k.

Hi Jon.
Did you give the car a good run before changing the oil, at least 5 miles, always best to have the engine hot when draining the oil, it helps it flow out better from the sump plug hole.

Car on ramps or axle stands.

Once you removed the sump plug, leave it draining for at least 30 minutes, remove the oil filler cap, and the dip stick, undo the oil filter cap at the same time.

Renew the sump plug/ washer.

Make sure its tight and re-fil with new oil 6.5ltrs diesel takes 6.8lts but you can top it up once it is down on the level ground again.

Fit oil filer cap and dip stick, start the engine for about 5 minutes, clear up then lower the car.

Leave for about 15 minutes, remove dip stick and wipe clean, dip it back in and remove after 5 seconds take the reading.

Oil should be about 3/4 up the level between min & max, oil should be fairly clean.

Top up to max if you like i always leave mine at 3/4 mark which is about 200ml short of max.

The garage I gave access to is a drive from my house so the car is nice and warm by the time I get there.

I usually jack up both sides to get access to sump plug, next oil change I will measure more accurately what comes out although from reading the forum there must be a certain amount left in hard to reach places, total capacity as mentioned is 6.8l but I don’t think I have ever had to put that much back in.

I may consider using a bottle of flushing oil, actual oil not flushing additive, as once run this will help to dilute the old oil left in the system.

Many thanks for the advice.

Regards

I hope you do not get under the car with just jacks supporting it.

If my experience is anything to go by you won't need flushing oil. My car started off as a company vehicle so serviced every 15k miles or so by a main dealer. I bought it when I left the company and carried on with using the official service schedule and service sheet.

It has now covered more than 427k miles and nothing lubricated by the oil has ever been replaced. Engine still runs sweet - well sweet as far as stone crushers go.
