Re: [DML] What gas octain to use

["David Teitelbaum" <jtrealty@xxxxxxxxxxx>]

If your engine is pinging on regular gas you have to check the following:
Timing, mechanical AND vacuum advance
Temperature, if the engine runs too hot it will ping
Spark plugs, if too hot a heat range they will glow
Vacuum leaks, if large they will lean out the mixture
Carbon deposits
Bad ignition wires, if they break down the engine will misfire and
sound like detonation.
It is also possible, if you are not using a branded gas, that they are
not giving you 87 octane or there could be water in the fuel. Just
some things to look at.

car at Grady's in March and Pat checked the fuel pressures, mixture,
etc. and still I have have pinging on low octane gas.  It's not > DCO
