hi Pierre,
98 octane - premium unleaded.
the oil level was very high, but the oil wasn't particularly diluted. it was within a few inches of the top of the pump. i removed the dipstick and let much oil out, but wasn't able to suck the remaining excess out. it probably ran better with the excess oil.
im pretty sure its pinging because it becomes worse with more advance.
maybe the pump is incorrectly timed?

next step- lets look at the oil levels in the pump. If the oil is low, the car may ping.
if the oil is too high, the car will smoke.
second, is the ping a mechanical noise? or is it certainly coming from the combustion chambers?
