It seems that a lot of automotive manufacturers have abandoned the use of straight mileage as a determinant of oil life. Many (most?) newer cars come with oil life monitors that take other factors into account.
I have no way of running a complex algorithm to factor in engine tembperature or to count total engine revolutions, but what I can do is determine OCI based on total engine hours, like someone would for a piece of farm equipment.
I have an Ultragauge set up which counts this automatically, all I have to do is choose to display it. The way I figure it, the engine doesn't care if I'm cruising at 40 mph in 3rd or 55mph in 4th, but the odometer does.
So what would be the time equivalents of the old 3,000 miles OCI vs. a modern 7,500 or 10,000 OCI? What range is safe and reasonable to run an oil? And for someone who drives his car very mildly, is there a major flaw in the thought process that I might be overlooking?
