Would it be a good idea to run a clean phase with Castrol GC? Or should I just run the maintance dose? The car in question is an 03 Cobra with 20,000 miles. I know that the engine is clean, but lets face it I am OCD....
I used the search function but....no dice
Also what would be a really good dino or syn for the rinse phase?
Thanks
