Originally posted by bighead: A friend of mine has a 98 5.9, and his pings like crazy. He took it to the dealership 3 times, twice they rebuilt the engine to try to resolve the pinging issue. They told him that there was nothing they could do, because the 360 is the same design now as it was back in the the 60's, and in order to make it meet emissions standards Dodge had to lean it out
(which caused the pinging). The only way to circumvent the pinging was to use premium unleaded, especially if using it to tow. If you tow a boat or any semi heavy load it will ping like crazy, even on 93 octane. Also he said the fact they leaned it out causes the gas mileage to go
. He averaged about 15 maybe, and that's mostly highway without a load. I know trucks aren't exactly fuel efficient,
but he said that was rediculous.
