My '99 Montana is coming up on 90,000 miles. I have always used high quality gasoline ( Shell, Mobil, Texaco) and have been a stickler for 3,000 mile OCI's ( this is the "Mom Mobile" and she uses it for non-highway short haul trips 90% of the time). It gets injector cleaner at every OC and a fresh PCV valve every year. I put in a K&N last year.
I have been thinking that "The Blue Bomber" may benefit from either Sea Foam or Chevron Techron Fuel System Cleaner. (Auto Rx may be overdoing it b/c I dont think that there is any fatal sludging ).
Is there any clear advantage to using Sea Foam [crankcase and fuel tank ]vs. Techron? Would using either be "overdoing" it considering that it is running pretty well. I would like to get 200.000 out of it if I can.
