Carbon buildup on piston heads from E85 do something about it? Also index 5-8 inject
So when going to NGK 5992 plugs I noticed some carbon buildup on the piston heads when the plugs were out when I shined the lights down the hole. I run E60 gas in the car. Also my injectors are index 5-8-5-8-8-8 they were updated in 2011 is that going to be a problem with ethanol down the road? What do you guys run for carbon buildup on the cylinder heads if any?
Ps my car is a 2008 E90 335xi n54
