Noisy, yes, Tedious, no, as those revs in third still translate to moving quite quickly. I spent about ten minutes with the oil temperature over 120 but it was not enough to clear all the mayo. I expect it will take a longer run, other people have reckoned on about forty miles. Seen another way, twenty miles at high revs would have busted something had there been anything amiss. There was no oil nor coolant loss, There was no power loss either and a good clear out reminded me what a good little sprinter a well sorted VVC is. I can see why people pay so much for an Elise with 160 BHP in two thirds of the weight. If I had the money, I would too!
