Your choice but not recommended by the manufacturer. You should look at the test done by Consumer Reports several years ago comparing NY City taxis with oil changed every 3k miles to those changed every 7.5k miles. My daily driver is an SUV with diesel engine - oil change every 10-12k mile. Wife's is gas with the same oil change frequency (both determined by the onboard computer system). The diesel oil/maintenance cost is higher - and factor in the ridiculous cost of diesel!!

My Cat engine oil change frequency is dictated by hours and duty. For light duty it works out to about 23,000 miles or every year. I can not imagine an OTR engine on a 3-7,000 mile oil change frequency.

Also, comparing NY Taxis that are in constant traffic to a MH that cruises the hwys is a bit much.......no relevance.

So, for me it's once a year regardless and that come to $300.00 at a dealer.
