Performance cars by nature are demanding on their engines. They say one track day is the equivalent to driving 5,000 kms on the road. And remember, performance isn’t just about going fast, it could be towing or regular spirited driving, but the wear and tear and pressure on moving parts and the lubricants is savage and will find any weaknesses. This is not the time to second guess the manufacturers recommendations. You must use the exact spec. or it could easily end in tears. This applies to the latest technology sports cars from Europe and Japan through to modern muscle from Australia and America.
Additives such as Oil Flush, Friction Reducers, and Fuel Cleaners and Conditioners can make a big difference from the first service and other additives can help as the engine starts to wear.
