oil changing? - the best way??

[bmwmini_cooper_s]

what's the best way it doing oil changes??? is it better when the engine is cold and all the oil is in the sump... or if the engine is hot???
and how long to drain all the oil??? is it better to wait until no oil dripping is present???
thanks!

change it hot and change it often... the advice of a MB diesel owner who had two identical cars both over 500k on the original drivetrains.

With syn oil (provided oxidation isnt your issue), 'often' is a relative term... but still change it hot when everything is churned up real well. I prefer to let it sit for a long while to let most of the last drops out.

Hot and until it stops dripping.

FWIW - My Toyota V6 will drip for hours and hours. I change it hot and let it drip over night. After the initial ten minutes, I change pans and let it go.... Next morning I'll have anywhere from five to eight ounces of oil in there!
Don't know if that would effect the engine being a "sludge bucket" or not, but it makes you think!

Wallys World,

I provide them the filter, oil, and $15 bucks and they get the privilege of crawling under my truck.

Since my cars' drain plugs are pointed to the side, I jack one side of the car up to get that last little bit out. Newer Golfs and Jettas are really nice because the plug faces backwards and you can run the car up on some ramps to make it drain more and get to the underside easier.

It is not necessasy or of any advantage to let the oil drip for extended periods If you have ever been inside an engine, there is alot of places the oil stays .

Change it hot, and within 15 minutes, ~98% of the oil that will come out, will have dripped out.

Further, some engines may be susceptible to loosing the priming on the oil pump if left to drain for an extended period of time.

If you really want to make your oil changes VERY easy, install a Fumoto Valve and change the oil when it is hot. You can change your oil without burning your hands and there is no mess.

JHZR2,
what is your definition of 'often' ?

thanks guys....

There is no reason to let the oil stop dripping or to drain over night or pour a quart of oil through or crank the engine over etc. If familiar with the insides of an engine you will know that ther are areas that hold oil, cause that is the way they are . It woun't matter or make a difference.

By the way, nice car. I was impressed with those on one of my track days. A mini cooper s did a better job than I thought it might against my 330ci, an M3 and an s2000.

Thats what I was gonna say.

Tell me how you are going to cause an automotive oil pump "loose it's prime".

I change hot and let it drip for a while...but not for hours or overnight.

If I'm really fussy , I pour some clean oil in to clean the oil pan a bit more.


The Fumoto valves sure sound tempting!

My four driving sons have it down to a science, they let me do it along with all the other regular maintenance.

Hopefully at some point they'll grow hands that fit a wrench!

Same problem here with an 18 year old son. He has no interest and no desire to do any work on his Blazer. Its easier and a lot cheaper if I do it for him, that much he does know!

Not as long as you do it for them.

It's actully quite common.

Loosing prime means you have a pump that will not self prime. If an automotive pump has lost it's prime you just start the engine and it takes a little longer to get to full pressure. There is no practical way to figure out how much damage the extra time takes, although it must cause some extra wear. Some domestic engies can be 'primed' with a drill and a long flat bit in place of a distributer. Run the drill in the correct direction until you get pressure up. I'd like to hear from anyone running a pre-oiler on the street.
