If you have a vehicle that consumes, say, 1 qt every 2000 miles, do you prefer to keep normal OCIs (whatever that may be for you), or extend them because you're replenishing with fresh oil more often?
What about if you're having to add 1 qt every 1000 miles?
One of our vehicles consumes 1 qt every ~1800 miles or so. It is driven about 14000 mi per year. I did the math and we'd use less oil overall if we did two oil changes per year (2x ~7000 mi) with more topping off vs. 3 oil changes per year (3x ~4700) with less topping off.
