mjpaque Report post Posted December 15, 2009 We recently purchased a 2009 Monaco Cayman. Regarding the oil change frequency on diesel engines, we have read and heard a wide range of recommendations. We are looking for answers to two questions. When should the oil be changed the first time? What should the mileage be between subsequent oil changes? Thank You, Mike & Penny Paque Share this post Link to post Share on other sites

And most RV'ers end up changing once a year, not based on miles. If you feel your use of the motorhome is unusual (i.e. pull a 7,000 pound trailer, all very short trips, etc) let us know the unusual circumstances and perhaps we can fine tune the recommendations. Also, call Allison (800 252 5283) with our transmission serial number. Until recently, they called for a main filter initial change at 5,000 miles. On very recent transmissions, that requirement has been eliminated. Brett Wolfe Share this post Link to post Share on other sites
