Should I stretch my car's legs regularly?

Thanks very much for your reply on fuel additives for a Skoda. In the normal event, it is probably the case that an engine doesn't get raced very often, and probably runs at fairly low revs most, if not all, of the time. Is there a benefit in running an engine, either petrol or diesel, from time to time at high revs and, if so, how often and for how long?

Your review of the Jaguar F-Type 2.0-litre was very interesting. I have one comment about the engine noise. There are times driving on a back road when it is a pleasure to hear an engine crackle and roar, but perhaps not always. I was driving along a long Spanish sea side resort behind an F-Type, where there were ramps and pedestrian crossings every couple of hundred yards. My thoughts were that one could quickly get tired of that roar every time the car started off again.

Perhaps, that's just me getting old and grumpy!

Hi Philip,

On the Jaguar front, first of all thanks for the compliment. As far as noise goes, I don’t think I’d ever tire of the F-Type’s V6 sounds, but that four-cylinder model is hugely impressive (and very refined) all the same.

As for running a car up and down its rev range, yes, it’s a good idea. Engines perform best (especially in fuel economy terms) when held at constant, low rpm (such as on a long motorway journey), but from a mechanical point of view it’s a good idea, once in a while, to stretch things out, warm things up, and get things moving.
