Sure, but if it takes 80HP to get up to freeway speed in the time you regularly need, the 200HP car is working harder than the 500HP one, as a portion of total capability. A 100HP car can easily go speeds that are illegal in the entire country (think VW TDI).About vehicles with more power being pushed less than a car with less power, it is not true. There is absolutely no way that anyone here can honestly say that if they sold a car with 200 HP and bought one with 500 HP, that you never push that car at wide open throttle.
Basically what we are saying is: no, not as a general rule, only kind of as a guideline. Honda engines have high PS/Liter, but most are quite reliable. 1970s GM Diesels have very low PS/Liter, and are incredibly unreliable. 1990s Mercedes Diesels have relatively high PS/Liter and are quite reliable.If I've been misunderstood I want to empasize, I wanted to know if less PS/Litre meant durable engine.
I wouldn't be worried. People abuse their engines much more by using the wrong oil, sitting all the time idling in traffic, etc.146K w/ ASP pulley and still running strong. Should I be worried?
Look for MB 229.3 or 229.5 ratings on the bottle. Valvoline makes lots of different oils.I've been put Valvoline on last service in official service company, is it right one?
