Hey peeps, I wanted to ask what the general opinion is with regards to preventing carbon build up on the insides of the 2.0 TFSI engines? I am aware this is an issue with these engines and obviously I would like to counter act this as much as possible. Prevention is better than cure and all that. So far I have found the following to be possible counters: Regular oil changes with good quality oil Fuel treatments every few fills High octane fuel Oil catch can system Would you all agree with the above? I would appreciate any input anyone has on this subject. Thanks.
