Please help. I helped my friend to change her car engine oil yesterday. it is a 90/300E. i recommended her to put in Valvoline Max life. Bosch oil filter. Everything is fine except that the car shake badly after start. It then idle normal as the oil pressure build up to normal...this has not happened before. What did i do wrong..Could it be the oil? Help..

My first response: Wrong filter. Go get a Mercedes Filter.

I have used MaxLife dozens of times and never had a problem.

I don't know if the engine you serviced is a 12 valve or 24 valve straight 6 cyl(M103 or M104 respectively), but in the case of an M103, you'd use Bosch Oil Filter 72165.

Along the way, I've heard alot of unkind things about Bosch Oil Filters. I do not know from personal experience that these comments are justified.

I do know that for whatever reason, independent parts shops in my area that specialize in German autos, for some reason or another, always try to sell me a Bosch VW filter for my 103 motor. The burst pressures, etc. in this Bosch VW filter are all wrong for my 103 motor.

Make sure you purchased the correct Bosch Oil Filter.

Its' been said here that Mann, Mahle-Knecht; Hengst are OEM quality oil filters for MB. I do not know if Bosch Oil Filters are regarded as OEM quality.

I suspect they are sold at Bosch Service Centers around the U. S. These places service MB autos. It would be hard to imagine they'd use an inferior product if staying in business was one of their objectives.

thank you both for your diagnostics. as of 9pm sunday night. I did removed the oil filter and changed with a another Bosch filter. the model of both filters was 72615. and i also make sure that the oil level is 3/4 between max / min. This problem only happened when the car has been sitting a while ( like more than one hour ) I asked her to give the result when she gets to work tomorrow morning. Let the car sit over night and see if the problem still there. if the problem persist, i will get the filter from the dealer. Thank you again..

if anything, that should only happen immediately after the change for a couple of seconds but never after the oil has already circulated throughout the system...
