I own an RV that gets driven very infrequently. I purchased it about a year ago and promptly changed the oil and filter and added auto-rx. I have only put about 500 miles on it in the last year. I hate to dump the oil and auto-rx but I am concerned about the oil sitting in there for potentially 18 months or so until I get 1500 miles on it for the clean phase. Any opinions as to whether I change the oil, filter, and auto-rx for the last 1000 miles?
Thanks!
Oops, just noticed that the recommendations have changed to 2500 miles for clean and 3000 miles for rinse. At that rate it may take me 24-30 months to complete a clean cycle. That seems like way to long to leave the same oil in the crankcase of my RV.
If your oil is okay in 30 months ( which it should be) start up your RV and fiinsh the application. There is no time limit. Your oil does not self destruct over time if it had oil life when you shut it down than it will have oil life when you start it up. Auto-Rx uses oil as a carrier only and wil not dedigrate.
