As a new member, I'm surprised I don't see a thread on the carbon buildup problem of our gasoline direct injection (GDI) engines. Aside from frequent oil changes and using synthetic (low carbon) oil, is there anything else that can be done to mitigate this problem which will start showing up at around 40k to 70k miles? Additives to the gas tank will clean the fuel injectors, but not the valves.

I recommend BG Products, particularly 44K. Here's a link to their products: https://www.bgprod.com/

THANKS. Like what I read about BG's EPR (Engine Performance Restoration) oil system cleaner. Will give it a try the next time I change oil.

CRC Valve & Turbo Cleaner is another product to consider. Youtube has several videos that provide info on it. To find these videos, search "CRC Intake Valve Cleaner".
