How long do the spark plugs truly last in my C6 LS2? My avg mileage seems to be dropping a little and am wondering if the spark plugs have anything to do with it.

Or maybe my right foot is gaining superflous weight like the rest of my body?

Just curious

Factory states they are good for 100,000 miles.

Don't know, we only have just over 13K miles on the 07! LOL!

Stop running diesel in your car. It will get better mileage on gasoline. The good stuff.

I had my plugs & wires changed last year when I was about 78,000 miles on my '08 C6. I'd started getting check engine lights.

But somebody told me if I didn't run diesel fuel I wouldn't be allowed to keep my truck plates.
