would like to do my own oil change. What size oil filter wrench do I need for the straight
6 sl320 (1997). I've read on this forum, I can draw motor oil thru the dipstick tube rather than remove the drain bolt on the oil pan. Any opinion on that ?? THANKS

generic oil wrench will do...

you can do either, draining from the pan is usually more straight forward for DIY mechanic...

Oil extractor pump through the dipstick tube is easier for me.

Note: This is just my experience with no intention of starting a "suck or drain" debate.

I've done both, and will just make a couple of points. Unless you own your own lift, anything that means you don't have to climb under a supported SL has got to be good for your health. Against that, sucking the oil through the dipstick is probably not as efficient as a conventional drain in getting all the crud out, and it's a bit slow. The only problem I had was that you need the oil nice and hot, and my (plastic) pipe kept collapsing under the suck, if you'll pardon the expression so try and get a metal probe. At the end of the day, ANY oil change is better than NO oil change.....

Oil change SL320

I have a 97 SL320 and I change my own oil. Here are my thoughts - you will want to get the metal "cap wrench" that properly fits on the top to the oil filter housing. I was unable to use a regular oil filter wrench due to the tight space on my car. The cheap plastic cap top wrenches won't work either. I chose to drain the oil after removing the drain plug - quite easy to do once you remove the front motor skid plate - no need to lift the car. By far the hardest part of tis job is changing the oil filter without making a mess.
