Yeah that is what most people do... I read up on it quite a bit, the pro's reckon 2000KM to change to full synthetic
Most guys also say nurse the engine the first 1000km, but then your rings don't set, it needs load and some boost to set perfectly...
I tried to keep below 0.3 bar boost and variable load for the first 1000km after that I drove normally, giving it good now.
Car just needs a good tune up now then she'll be 100% think the car is running way to rich but Calibrator will sort that out, think my timing isn't 100% as well.
another thing that I might need to do is get a surge tank for my petrol, blerry thing keeps starving when fuel load is low and sliding through a right hand corner.
