Patrick is always telling us to use this Seafoam additive and I always forget. My '02R has been showing some signs of knocking and I thought I would try some.
I had 100 miles on the most recent tank of gas, so I added about 4oz Seafoam and ran for the remaining 60 miles. Tried to run in Pat's pleasure zone of 5 - 7K for most of the remaining tank.
Refilled today with 93 octane ( at $2.97 a gallon!) and the knocking is pretty much gone.
Thanks Pat!
