Oil can cause detonation issues especially with questionable ring seal but I would like to see what % of detonation issues it causes. My "guess" is less than 10% where fuel causes 90% of the issues.
Back in the day I refused to run oil with graphite in it because of detonation issues. Looking back I'm glad I didn't join in on the graphite trend because I had turbocharged engines back then and even with good pump fuel, detonation was an issue.
Just a side talk. One day I was pulling a mountain with my 6.5 diesel when it was well over a 100 degrees out. My WT was about 265. Everything was in the red. All of a sudden my engine sounded like it was pinging. Just like a gas engine does. I'm like what the???? Is this thing detonating??
I can't really find anything to this day if that is even possible. I think my engine got so hot the diesel fuel started to detonate in the combustion chamber. Only a guess though.
As far as the little 4 banger goes. I just hope they get the duty cycle up on it. They have the power; it's the duty cycle I'm worried about.
