92 Fleetwood 454 TBI motorhome is in question. Rarely driven however started monthly sometimes bi weekly and oil changed out annually. 80k miles and it's gonna be second LOF since I took ownership. Rotella T5 10w-30 will be oil used. Undecided on filter. PO wasn't the best on maintenance so I want a decent oil filter to help clean/protect engine. Maybe 500-1000 miles annually. Lots of hills and hot Nevada Summers and cold winters.
Thanks
