The engine made by BMW, is port injected (so the intake valves look clean) and is all aluminum with Alusil liner. What product can I safely add directly into combustion chamber to dissolve the carbon? Has to be Alusil safe. Thanks.chemtooler answered 2 years ago • Eco-Friendly | Tire Sealant600 views1 answers0 votes
