RE: Changing Oil
Does anyone have any info on max mileage changeover. I just bought my hemi and its got 30 000 km's (approx 20 000 miles) on it.
Q: is it too late to switch over?
Previoulsy i had a GM with the standard start-up piston slap and crank shaft knock. I changed over to synthetic and the engine noise was worse. GM engine tech told me that it was too late to switch over to synthetic due the truck has 40k miles on it.
