anyone do their own oil changes on their c230? im going to buy the suction vac to take the old oil out but does anyone know what tube is for the oile on our engines is the one wiht the red cap or the one that says for mb shop only? anyone know size of oil filter wrench i need to buy? please help

 

red cap is oil.

 

I'm NOT a fan of the suction method, I prefer the good old-fashioned gravity way.
Plus I get to inspect the underside and clean it up somewhat

The big red cap is where you put the new oil.
Full Synthetic please

The skinny tube, where your Oil Dipstick tube goes into, is where you suck the old Oil out vertically, under suction.

good luck
