I have a 1995 325i with 89,000 miles. I have been using Amocco 93 octane gas with BMW's gas additive. Since 72,000 miles twice I have added BG's gas additive. I am running Mobile 1 15/50 synthetic oil for the last 2,000 - 3,000 miles. I have been having some heavy pinging recently. What is the problem.

Thanks for any input.

you might have a loose turning rod, if thats the case, you should get that fixed right away.

also, you should try using Lube Molly, its a german synthetic oil, its like candy for BMW's. I believe charlie had a pinging problem once and this oil fixed that.

I had a turning rod lose before, if your engine knocks at high RPM's then it might be the rod. Unfortunately, I didnt repair it, and it eventually wore though my block. It was a rare case on my part since M30 engines are virtually bulletproof.

The turning rods are in the block of the engine, so its probably a big job.

In your case its probably not as severe, try the oil first and see how that goes.
