I've recently started in a new career field in which I drive 50 miles to the location, sit idling 10-12 hours, then drive 50 miles back.
I normally change the oil in my Crown Vic every 3000 miles. I remember reading somewhere that Ford recommends accounting for 25 miles per idle hour. With that being said, each day would be the equivalent of 350-400 miles. 4 work days a week makes an oil change every other week, if I were to try to stick with my normal OCI. I know the modular 4.6 is usually easy on oil, so the 3000 mile OCI isn't a necessity.
Should I factor in the idle time and just go for a 6000 mile equivalent, moving to monthly oil changes? Should I stick with actual mileage and not worry about the idle time? Or, should I just go to a time based oil change (every 3 months, etc) instead?
I'm currently running Castrol Magnatec 5w30 (local DG clearanced for $2 a quart to me) and a Fram Ultra. I've gone 2 weeks of work on it and I'm starting week 3 on Friday.
