E350 pinging with premium gas
I just drove our E350 tonight with the windows down and I noticed it was pinging badly. If I took off with a good amount of throttle it would ping,and when cruising along and suddenly giving throttle it would also. It was knocking waay too much. I noticed this with a C230 V6 loaner we had too, but I figured it was because of the cheap low octane gas people put into the loaners, but we only use Shell V-Power. Is this because of the V-power, or there's something wrong with the engine? Has anyone else noticed the pinging on these new V6's?

First, put a can of octane booster in the current tank of gas. Second, fill up with a high quality different brand. If the pinging stops, this will eliminate bad gas as the source of the pinging.
If it doesn't, then it's dealer time. Could be a number of different things: bad knock sensor, crank position sensor etc. Worst case is excessive oil seeping past the rings or valve guides. Have you checked your oil level?

It's dealer time, period. If the engine management system is working properly, the car won't knock even with low-octane fuel. It would just have less power and/or less mileage. The fact that you're getting knocking/pinging/predetonation is sufficient evidence that something mechanical or electronic is wrong.

Puh-Leez... Normal my butt. Todays engine management computers have more than enough intelligence to retard the timing if they detect pre-ignition. Ask for someone to actually look at your car at the service department, not leave it parked outside all day and then blow you off!
