Why is it more common in a DI engine vs port injection? Realize FRP is between 400 & 2,200, but actual amount of fuel in chamber is same or less.
2010 EB engines use 5w-20 vs all later EB using 5w-30. Was told by dealer and tuner(s) to use what factory recommends. So, wouldn't 5w-20 be even more cause for concern? I have never smelled gas in my oil, which I change myself.
Got slammed on SHO Forum by one guy for questioning all this. I certainly don't mind being wrong, I just want to know WHY and what we should do to keep this to a minimum.
