Well, here it goes:
The car (1984 chrysler fifth avenue, stock 318, stock drivetrain, just hit 80,000 miles) has been running great until about a month ago, when I accidentally put mobil semi-synthetic 10w-30 in the car during an oil change. (they need to label the bottles better). When I started the car to drive it afterwards, I noticed a very mild knocking sound, kinda sounded like rod knock, could have been the fuel pump, not sure. I didn't really worry about it. I should also say that...
Help me ease my mind.......Rod Knock???
