Siena: Much will depend on the engine in question, as well as how well it was maintained. But generally, a typical 4 cylinder petrol engine in a modern vehicle will do in excess of 260,000 miles, before any major repairs are required.

thelonestranger: So am I safe to buy a car with 150kilometer on it without expecting engine repair soon ?

Siena:

Again, I will state much depends upon the engine, and how well it was maintained. You don't say what make / model you're referring to here.

thelonestranger:

I am considering several vehicle options

CHIMCO: Sir please i was travelling with my M. Benz sportline e300 6 plugs engine, i noticed that if i acceralate the engine rpm will raise to half while the speedmetre will be little above 40. If try to increase speed the rpm will increased further, i became afraid. Atimes the car will quickly surged forward. I dont know whether the engine is getting old or dying. I always service it with Mobil Super XHP 20w-50. Pls i need ur advice.

your engine is doing alright from my reckoning. it generates the power required of it. The problem is your transmission (gear box). It isnt transfering that power from the engine to your tyres. It is slipping. I don't know a lot about about transmissions cos they are so complex and differ from one vehicle to the other. However, here is what u can do. Check your vehicle manual if you have one for the recommended transmission fluid and buy it. Flush the old fluid out and either wash the filter or buy a new original one. Replace the filter and fill up with the new trans oil. Most times this fixes the slip problem in most transmissions. if it doesn't fix yours, the experts in the house might offer some other solutions. cheers.
