Interesting. Seeing the fuel dilution, although not that high it is still higher than it needs to be. Nitration is good so that is showing that it is efficient on combustion. TBN being low isn't great at all for the miles on the engine. To think there are individuals out there that are using this and going 5k or longer.
Doesn't RotoFab make a dry filter? That would be a better option IMO. If I had to do it all over again, I would have not put the GM cold air intake on mine and just used the stock filter set up and just changed out the tube from the filter box to the intake. Then ran Fram air filters and changed them out every 10k or so.
The only thing I use an oiled air filter for is my cabin air filter. So I got a K&N for that.
Did you use any fuel additives? What grade brand fuel?
