Quick check, its been a while, for the smaller engine in the CLK320 is that 7 or 8 quarts of oil I need?

Thanks!

dynomite05

8.5 I believe. Wait until someone else chimes in. lol

billyhead1

The oil change amount is about $130. That's what I know. ;-)

dariusf

crap I was hoping its closer to 7 They do not sell the big jags here in Chicago for the 0W 40 so thats $8.49 / quart but Autozone has a $10 off coupon My indi mechanic did it at $60 plus my filter so I gotto give him a call I guess, there goes my plan to do it myself The vacuum pump guess will stay in the box...

i know 5.5 L takes 8.5 i highly doubt 320 takes as much.

bheng

its 8.5.

the thing i cant figure out. is when i put 8.5 and turn on the car it reads at 8 but i figure its cuz .5 runs through the engine and filter. so iono if i should put 9 so theres 8.5 while the engine is running or leave it at 8.5

if you can wait, try to find the deals at the autostore where they give you an oil filter + 5 qt for 30. and get 2 of those. do you need to do it now?

dariusf

Yes need to do it ASAP, well I'm maybe at 4k mark on that oil but its over a year now. Not sure how long I can run on the syntactic time wise.

I never see these types of deals in Midwest area, its only for the 'normal' oil never 0W40.

Mobil 1 0-W40
8 ½ QT With Filter

Ang you can use an engine Flush before you change the oil and it will clean up all the gunk built up. But stick to Mobil 1 Oils =]

dariusf

Yes always Mobile 1 0w40 but question I have now is how long can I go on this, can I go well over a year with out changing it. Its a syntactic oil after all so it should last far longer time wise. I only put on maybe 4k miles a year. With my previews car I used regular oil and changed once a year. I know I can easily go 7-8k miles with the syntactic, just not sure if I should still change it after a year and 4k miles or could keep it for longer, lets say change it every 6k / 1.5 years.

BENZADI

Honestly I Change my Oil every 4k just to be on the safe side and try to keep my K&N air filters clean as possible, if you dont drive it too much at least turn it on a few times that you dont drive it .

dariusf

I think 4k is a major overkill its syntactic oil after all. Even with regular oil in my Wife's old RX330 Lexus it was every I think 5k miles as far as manufacturer recommendations. In my CLK I drive 8 miles a day 4 times a week plus a few extra miles here or there. I know the engine gets much more abuse with these short trips (4 miles each way to the train station and back) but still I think 7-8k miles is fine. Just not sure on the time.

bheng

im sure synthetic oils last for about 2 yrs. then again, thats a shot in the dark

12secCLK

im due for my oil change for a while now probably nearing 10k now longest i have ever taken not changing oil... and my k&N filtes haven't been re oiled since day one that was like 30k miles ago lol.

dariusf

you oil the oil filters?

12secCLK

no you need to Re oil your k&n air filters after a certain time mine are dried up.

dariusf

oh right forgot, I have K&N oil filter waiting for the oil change but for air filters I use MANN Filter, they make the Mercedes OEM ones, these under their name are identical minus the mercedes logo
