My mate has just bought a 6 year old BMW M3 - its the last V6 one, so pretty tasty. Anyway, he took me for a spin in it, and for the first 15mins tootled about, barely getting out of 3rd gear.. Perplexed (and slightly worried) I asked him why he didn;t just release all 500 horses! He advised that performance cars need to be warmed up for a bit before going full whack, and that actually i should be doing the same in my Fizz ST. Now, I'm not going to pretent my 1.5 ST2 is even close to the same league as his 3L V6, BUT it is a tuned engine? So should I be taking it easy, or actually totally fine to hoof it from a cold start.. Thanks!
As the others have said, you definitely don’t want to be hoofing it from cold! That applies to any car, performance or otherwise. It’s not just to allow the oil to do its job but because tolerances within engine components change as it warms up. At the very least you want the coolant to reach it’s normal operating temperature, but in the RS I wait for the oil temperature to increase a bit as well. Obviously the Fiesta doesn’t have an an oil temperature gauge but I know how far I get in the RS so I just wait until that point, not very scientific but better than nothing. I know some of us have differences of opinion on running in a new engine, but I think everybody would agree that caning a cold engine is a no-no....
