octane

[Cummins]

I am very serious about getting a 2003 or 2004

My concern is how the car was driven regarding using the 91 or 93 octane?

Is there test i can have done on the engine to give me some confidence there is no problem if the higher octane was not used.

and any other thoughts I sure welcomed. Soon as I sell my toy, a 1999 2500 cummins dodge, hello Marauder

I would think an oil analysis would be a good starting point if you have a concern. I am not well versed in that but that would be my suggestion

Honestly you just need whatever premium is in your area. Typically it's 91-92.

There is no test to see if a car has been running 87 octane. If it runs and idles good, no stumbles on wot and no pinging then prolly good to go

Your way over thinking your approach.

You are a smart man /Dump that vintage dodge Chassis[poor design] and shoe horn that Cummins engine into something else ,meanwhile enjoy the Marauder.

^^^What he said^^^

I bought mine from a Ford Engineer with 28,000 miles on it and he used 87 octane. I started putting 93 octane in it from the time I bought it and have had no problems. Good luck on your search!
