Did this today... 30 minutes. A few pix for those not sure. Used about 6 litres, just filled to the top mark on dipstick.

1. Loosen filler and filter caps.
2. Put in sucker ;) and pump (20 pumps on mine)
3. Few more pumps and wiggle end to ensure all oil out and lift out and up so tube drains.
4. Remove filter and cap as one unit.
5. Clip new filter into cap.
6. Replace O ring if req.
7. Replace filter assy. Nip up tight just enough so it cant come undone.
8. Fill with new oil (put 5 litres in 1st) Quicker to put in thru filler cap in rocker cover than thru filter housing.IMO
9. Replace filler cap.
10.Start engine, run for 10 secs then stop.
11. Check level then fill with approx 1 litre until up to 1/2 to full on dip stick after 1 min or so.
12. Recheck for tools etc, leaks, mess anf close hood.
13. Recheck next morning in you want.

schaf1945,you can get the same pump as bazzle uses at:

pelaproducts dot com

the model is a PL 650 and it will extract 6.5 liters which is perfect for the 230 4 cylinder sump.I got one a while back and it will spoil you on oil changes.It also works well for smaller,US engines,that typically have 4 quart sumps.

They retail around $85 but you can find them on line a little cheaper.

Hey, Bazzle, where's a good source to get the reset tool and OBD II tool I keep hearing about. What are the approximate prices?

what type of oil do you use?
0w-30?
0w-40?
10w30?

I've been trying to figure this out all day with no success....everyone gives me a different recommendation for my 2003 slk230... :(
Depends a little on where you live

Generally 0W-40 Mobil 1 if low miles
I use 5W-50 Mobil 1 in Australia with great results

The important thing is the low end rating for cold starts in USA /Europe

The high end should not be below 40 (there is a Benz note on 0W-30 not having high temp shear strength)

I'll try and find the benz oil recommendations where they don't like 0W-30 as being too light for the spec relating to models in the SLK year range.

Short answer from what I've read is that it is a bit light (even for cold weather)

The synthetic oils have the ability to go down to -50c without freezing and if you look at your service handbook,(graph on page 14)-- 0W-30/10W-30/5W-30 are only good to 86F (30C)

There was a good post 5 weeks ago regarding oils - performance/comparisons

Given that you can get a 5W-50 oil,I feel comfortable having the low viscosity for startup and the protection of a 50grade when hot for 40C temps in our summers here.
In addition, the 5W-50 stays pretty clean for 8000kms on a 140,000km engine.

I'll try and post the recommendation

Mercedes-Benz Engine Oil Recommendations


some oils which are not recommended:
Mobil 1 SuperSyn 0W-30 SL/SJ/CF A1/B1/A5 9.7 doesn't meet 229.1 nor ACEA A2 or A3
Mobil 1 SuperSyn 5W-30 SL/SJ/CF A1/B1/A5 9.8 doesn't meet 229.1 nor ACEA A2 or A3
Mobil 1 SuperSyn 10W-30 SL/SJ/CF A1/B1/A5 10.1 doesn't meet 229.1 nor ACEA A2 or A3
These 3 oils do not meet MB spec of > 3.5 cP for high temperature high shear strength.



--------------------------------------------------------------------------------

Note the bit on non recommended oils

You'll notice that 1998-2004 vehicles can use oils to Benz spec 229.3 and 229.5

Could we add oil drain plug torque specs to those without the oil sucking thingie?

All the best,

Raymond,

Note that you should use a 6 faceted socket rather than the normal 12 - the plug head facets round off easily (by design, to protect the thread in the much more expensive oil pan!)

Oil choice depends on your climate -synthetic 0w-40 would probably suit where you are.

Miles of opinion on this if you search
