I don't think I have ever had an engine that I didn't have to have the carbon removed after 50 gallons or so.
This is just the cost of our hobby. I have an engine now that has been sitting following an crash.
I have to clean it up, decarbon it and order some pieces to get it running again.

Yes I know.
Thats also the oil that Mike Dooley was recommending me when I purchased my 80 RV. 5 gallons later at 32:1 the pistion was hitting the dome... 75$ to de-carbon.
It may not be crap but I'll not use it again.
