I’m buying a new diesel jeep next year and I have a couple of questions.
I have heard (but never read in an owner’s manual) that when you first buy a vehicle you should not exceed a certain speed for X number of kilometres. Apparently the engine metal needs time to be tempered or something. Is this true? And is it the same for both diesel and gasoline engines?
I have also heard (again, never read) that vehicles which aren’t sometimes driven at high speeds will never reach their full power potential. So, I guess, if Granny gives you her old car and she’s never driven faster than 60km/hr then you’re not going to be able to fly down the expressway at 140 or anything. Does anyone know if this is true?
