Congratulation on buying your Clio Cup 172!
A lot of things have been written about how to "run in a new engine"
Some say run it in gently
Some say thrash it from day one!
Some say a genlty run in engine is always sliggish
Some say a thrashed engine goes like a whippet
The chioce is always yours!
When I buy a new car, I always make sure the engine is at normal running temperature, and then thrash it to within an inch of its life! Always end up with a fast responsive engine. This doesnt seem to have any long lasting effects, but then i change my car every 3 years!
Hope that helps and welcome messages from others who may have different ideas!
