I am surprised

[Rod Brown]

I just turned 51000 miles on my 06(stick&Z51)and suddenly,the pick up in my car increased and the idle smoothed out and I am stumped.I haven't done anything to my car.It's stock.No,its not my imagination.Any clues?Thanks for any input.The gremlins are at work.

Fuel formulation in your area changed from winter use (it happens in my area), carbon deposits removed from injectors intake valves and pistons? Hard to say really. Glad to hear it though, enjoy.

You must have got the optional: If you liked the 1st 50,000 miles, wait until you hit the 2nd 50,000!

FYI- The Calif (CARB) fuel change rules are Feb. 1 and Oct.1. (Winter blend to summer blend, etc.) Because all tankfarms must have the new blend by these dates, the refinery's start producing/delivering new blended product about 6 weeks prior to these dates.

Thanks for the input.I would never think the change of fuel could make that much dfference.I learned something new today. Rod
