87 or 89 or mix

[Jako]

If I was towing over 5000 lbs obviously I would use 89. Over 250,000 miles running only 87 octane is pretty good proof for me and perfectly suited to my driving requirements.

Interesting card from my 2001 Dodge Ram SLT
see post 73 and 75

What octane are we using?

No need to get passive-aggressive about it. I never said anything about pinging, nor have I ever heard anything like that on this truck or my previous one. Of course damage could be happening if you actually are experiencing that. No need to be so sensitive, there was nothing aggressive in...
