My '08 Dodge sees ALOT of miles (4-5k per month), but it does also spend quite a bit of time idling around our orchards. On average, the truck idles about 20hrs per month, and up to 40 hrs in the summer months - usually with the AC on and an ambient temp of 90-105 degrees.
The truck only averages about 13 mpg with my driving habits, so with the current OCI (German Castrol at 10k with filter change/topoff at 5k), the engine will be burning more than 750 gallons of gas between oil changes.
Since oil pollutants are generally created as a result of combustion, then is a v8 engine that has burned twice the amount of fuel as a smaller engine over the same distance likely to have less TBN remaining in the oil?
