Tip & How-To about Mercedes-Benz ML-Class

Oil specs matter

A lot of times we do change oil by ourselves, no need for a garage as long as we do it in a safe way for the enviroment. But not always we get the oil specification right. Fine, let's give an example of a 5W30 oil, 5W30 is and will be always for most of us 5W30. Well, not exactly. It is better for us to choose the correct oil velocity, manufacturer (recomended by engine type), rather than later on wonder how come my check engine light came up, or suddenly the car lost its power, does not go above certain RPM's. It does not matter if your car is 10-20 years old but it starts having a sense when it comes to younger cars. Most of modern cars are full of different sensors, control units etc. All connected to one ECU that you can say it is a car's brain. My friend got a certain type of oil made by one of leading companyon the market and put into his 2005 diesel engine. Car ran perfect for about a month when suddenly during overtaking the engine stopped, just cut down. Full tank of fuel, all filters changed, timing chain did not snap (he could have heard it and it could not at just 37,000 miles). He started the car again waited for the computer screen to come up and it said ENGINE MALFUNCTION, slowly drove up to the nearest garage, they've put it via diagnostics, result was that one of sensors is faulty. Mechanics told him to buy it, he got one - original unit (not really expensive). They fitted it, checked everything seemed to be fine. He drove off got to 2500rpm and the engine stalls, won't go anymore. Finally he went to the car dealer, they checked the computer and the first question they've asked was: did you change oil? He replied yes. Did you put X oil? No- he said - but of a same spec. Well it came up at the end that specs were not the same as X oil has a special thing in it. Engine needed to be cleaned (flashed) inside of the oil he put in. After that copule hundreds less in the pocket but the car goes as new.
It does cost a little more to get it done right, but it can save you money at the end.
I had to choose a car model and make but this actually is for all the new model cars.

rusty gas filter


You could do these yourself. But, you would need a good mechanical knowledge and a decent tool kit. The most difficult of these is the ball joints. Just because they are always fiddly. The fuel filter is either screw on or plug in. and the sway bar is dirty and awkward. Ideally you would use a car lift to do these jobs.

What kind of maintience need to be done on a 2003 Z71 fwd ?


Change the filter with each oil change. Unless your towing, the tranny filter is usually 60k miles. Check your manual to be sure. Your manual should spell out when maintenance is to be done. If a garage wants you to do some outrageous expensive maintenance, have another garage look at it.
