2004 Nissan Frontier - 4 cyl - KA24DE engine- 120K
I have been buying Shell 93 for about a year and the truck runs great and doesn't ping during uphill acceleration, but the 93 octane is about 50 cents more/gallon and I have been thinking this is overkill. Last week I filled up with Valero 87 (top tier gas sticker on the pump). Well now the truck is back to pinging under acceleration on hills etc..
I guess I thought the 87 would not ping since it was top tier but it does.
I have seen all over these forums where buying 93 octane is a waste of money for a truk such as mine.
Thoughts?
