To give vehicle background: 2016 F-150 with the 5.0. Owned since 48,XXX miles and have nearly put 100K on myself now. Not an issue from it and always a synthetic oil and quality filter ran. Has been a 1/2 quart short maybe twice at an OC.
I have recently decided to shorten my OCI's from roughly 7,500 miles max to approx. 4,000 in an attempt to hopefully clean up some buildup/varnish in the engine a little. This will be the first OC at 4,000. By cutting the interval nearly in half, I began wondering if I should consider leaving the filter on for 2 OC's. I did my best to use the search function to gather the information I could and it seems (from what decent information that could be sifted out) to be a split decision as far as BITOG goes.
In the approximately 4,000 miles (5 months) on the current filter (Fram Endurance), there have been a few longer road trips, but the majority of the miles are commutes to and from work and trips to neighboring towns. Trips that would have the engine running 30 min at max. I am switching from M1 FS 0W40 to Valvoline EPHM 5W30 if that should be a factor into the "go / no-go" answer as well.
For those who do use a filter for 2 OC's, what factors should I consider into the final decision?
With my truck, the messiest (and sometimes longest part for a big guy like me) of the OC is the filter swap with the position Ford has it on the engine and so the idea of not having to deal with that is kind of nice to consider, too.
Thanks in advance for any and all thoughts and help!
