Thread: Engine "Ping"

  1. #1

    Default Engine "Ping"

    Purchased a 2009 Silverado Crew Cab back in May of this year. I've noticed a "pinging" sound sometimes when I start my truck but mostly when I'm cruising at 1500rpm. I've talked a buddy about this and he said he was told it was common and it could be the type of fuel I've been using. I use Chevron Unleaded but I was told to use a higher grade to see if this helps.

    Any help would be appreciated.

    Could be a bad knock sensor. Higher octane could help, but that's more expensive than a knock sensor. Any DTC codes?

    GM recommends premium fuel be run in all their new cars and trucks.
    We had the same problem with my wifes 08 HHR.
    Pinging can be harmful to the engine, in extreme cases it can damage the cylinder heads.

    the octane shouldnt be the problem, all new engines can adjust for that on there own, i have never seen anything about a truck needing premium, if thats the case why would anyone buy a truck. higher octane is now more for supercharged and tubrboed cars, not even the direct injection engines "require" premium gas it helps but not needed. I would look at the quality of gas you are putting in it, and its 09 take it to the dealership it has a warranty
