walmart supertech 15w-40 oil, CI-4 rated, not the old CH-4 stuff. No oil added, about a quart burned over the interval.
1989 Ford F-250, 7.3L IDI International with aftermarket ATS turbo (has exhaust leak == no boost most of time). Running a K&N air filter.
Mileage on oil is 2373 miles, time on oil was 6 months almost to the day (from October till April). Truck odometer at 136000. We had a cold winter too, one day truck wouldn't start because batteries were frozen.
