Well I put a can of this stuff in the car, and filled up with Chevron's Techron 93. The slight pinging I had at high rev before is gone, running Bama's 91TQ tune with no timing backed out (and it feels strong).
Question: I have a dyno-tune appointment for later this week, and I still have a ½ tank of fuel that contains approximately ½ can of Seafoam...does the Seafoam raise the octane rating of the fuel? Should I ensure I burn through that fuel (about 100 miles of driving) and refill with fresh Techron 93 prior to the dyno-tune? Or is the Seafoam just a cleaning agent that doesn't affect the octane rating either way?
