The Mercedes petrol engine will last about 300,000-400,000 miles.
If the factory maintenance schedule is strictly complied with.
If you put gasoline/petrol in the oil resivoir of any engine, you will destroy the engine if you do not drain the oil and add fresh oil immediately. Start running that engine and it will not last long.
The first Patent for a petrol driven car was 1886
some mercedes last 3 years but some expensive ones last 20 years
20 to 30 years
Diesel run in any petrol engine will do damage if you can keep the engine running for a long period of time. A petrol engine will not start and run on diesel fuel alone Posted by Danny from Bee Mech Mobile Mechanics
That depends on the engine size.
Toyotas and Hondas are the best vehicles and they both last a long time.. and are almost maintaince free Mercedes-Benz, is the best, i have a 86' Mercedes and it has the original engine 1.235.000 km and still working and you can find second hand parts for free in Germany, austria, Albania, Bulgaria,
There is no way to know how long it will take for the transmission on a Mercedes Benz CVT to fail.
It won't, even a mixture of gasoline and diesel will not work. May I add that running petrol in a diesel will destroy that diesel engine.
i'll say less than 20 min.
Long Enough
I have C280 1995, the battery has two years and it is ok. It is important how often you start and use the accessories of the car. The continuos stop and start the engine is the worst for the life of the battery. Sometimes, the last is a matter of luck.
