  • S14 Oil change - walk me thru it.

    Sorry in advance for my noob-ness and lame question, but this is the place to get info on the S14, right?

    I don't have an owners manual, and haven't yet been under my new to me E30 M3. So I can be fully prepared before I do the oil change, can you tell me what tools I need for the job, and the recommended sequence of events for an E30 M3 oil change. I plan on putting in Mobile 1 15W50 and get either a Bosch or Mann oil filter.

    I will probably jack up one side of the car to get under it, and use a strap wrench to remove the old oil filter (from below or above???)

    Also, how much oil do I need to buy?

    TIA,

    If you jack up under the left side, this will make the oil run towards the sump plug on the right side and give you space for a tray to catch the oil from the filter on the left side.

    To remove the filter, firstly remove the air filterbox (2x10mm nuts on the left of the box, the big hose clamp and the Airflow Meter plug). This will give you access to the filter from above.

    Mobil1 15/50 is fine, but get an original BMW filter. They are cheap so why take a risk?

      Jack up the drivers side from the appropriate jacking point! or frame rail. You will probably have to remove the intake boot to get at the filter. If your arms are skinny/long/strong enough you can unscrew the oil filter by hand from the drivers side. If not, then use a filter wrench. There will be some oil spillage which can be minimized by putting a plastic bag over/under the filter while removing it. Hand tighten the new oil filter. The oil pan drain plug should be 17mm IIRC. Should take about 5 qts with filter change. Also, consider getting an aftermarket oil pan baffle installed if you don't already have one.

          Please make sure you use a jack stand if you or any part of your body will be under the car. Do not trust the jack itself.

            Got er done! Thanks for the advise, I owe you all a beer!

            I picked up a filter and washer from my local independant BMW specialist, and the Mobile 1 from a local NAPA parts store. The M-1 15w50 was over $7 per quart!!! $1 more than all other M-1 oils, which are already expensive to begin with! I also found out that I have a K&N air filter, and it was dirrrrrty! I cleaned, dried, and oiled it up. All in all, car runs quieter as the valves seem to tick less, and I'm guessing I will get a bit better fuel mileage with the clean filter and engine oil. I think the PO went a bit too long since the last oil change as the oil was VERY black, pretty much zero transluscence and somewhat thick in its warm state as it drained out. That kind of scares me! The car is in good hands now.

              maybe you might want to get your oil checked out.

                Great idea! I just ordered 2 kits so I can test the oil in both of my cars. Unfortunately the dirty oil from my M3 is in a container mixed with dirty oil from my other car :( I'll test at my next oil change.

                  I did not even have to jack up the car for my oil change. I used a fluid evacuator pump to suck out the oil from the dip stick tube and then took out the oil filter from the top side.

                  Yeah it took an hour but ...who am I kidding, I will jack the car up next time and grab the filter from the bottom.

                    The filter was easily reachable from the topside. Jacking up the car was easy, and allowed me to put a pan under the car and easily reach the drain plug. It took me a while to do the oil change, as I added in there the time to take out the air filter, clean, dry, and re-oil it. All in all, I think I was into the oil change in under 1 1/2 hours, including the air filter project, which took about 1/2 of the time.
