Thanks txbest1980,
I'm familiar with Seafoam. I'll give that a try. Won't hurt, but it seems as though I'm somewhat in the ballpark with my current mileage and driving style.
I also own a 2001 Vette, convertible, 6 speed manual
. I used Seafoam on her when she had about 28,000 miles (about 18 months ago). I did both the crankcase via PCV valve and poured the remainder into the gas tank. I and my buddy, who helped me to put it in at work at lunch time, expected a ton of smoke out of the exhaust after sitting a few hours. To our surprise not a puff of smoke was visible at start-up and on the drive home she was clean the whole way
. I did have the oil (Synthetic also)changed right away, though.
