Pinging on Sunoco 260
I thought 260 was the best.?!?
Always OK before but this time I lost power and pinging with last fill up.
Waited til 1/2 tank amd filled with Exon 93 oct. no more ping!
Friend told me Exon was the best and most consistant.
I guess he was right.
Anyone have any Gas peoblems or recomendations?
