Richen Posted November 28, 2007 Share Posted November 28, 2007 Does any one have engine knocking on your GS? The knocking is much lighter than some diesel engine. I heard the knocking sound when the engine was cold. After driving for 10 minutes, the knocking sound reduced, but still can hear the knocking with radio off. The owner’s manual mentioned that the engine knocking is normal when engine is cold. It should go away after a while. Will that be a problem in the future?

Mad Dawg 350 Posted November 28, 2007 Share Posted November 28, 2007 What I believe you are hearing is the sound from the direct injectors. Nothing to worry about, perfectly normal. Quote Link to comment Share on other sites More sharing options...

I'm on the road traveling at this time but, if I recall the owner's manual correctly, it states to use a higher octane fuel. We have always used regular with fine results but you may be getting some discount fuel that isn't very good. Just a thought. Try some premium from Exxon, BP or Shell. Again, just a thought. It's worth a try because the dealer will ask what fuel you are using. Quote Link to comment Share on other sites More sharing options...
