Watford City, ND | I would guess that it's close, the 22 mph average. I drive a lot for work, about 42,000 miles a year, and my 2015 Ram is on 15,000 miles between oil intervals - it also has a hour meter and so far I've been real close to 385 hours per 15000 miles (39 average). I'm tempted to extend my oil interval to 500 hours considering I'm using full synthetic, but so far I haven't. That would put me at 19,500 miles between changes. | |
