Spark Knocking
2013 F350 with the 6.2L. Around 44,000 miles.
Pulling the Work & Play, I guess we're around 15,000 lbs. total. I've been noticing lately some detonation; especially on hills. I've read before that some detonation is OK and expected when towing big loads. But I tow with this truck a lot.
Should I be concerned? Should I go ahead and bump up to 89 octane?
