 North Central OH | Possibly maybe not the filter based on the wrap they get, maybe change the filter a few times. Outside of that depends on use and the vehicle 20k would be 500hrs on an average vehicle, don't think too much at taking new diesels to those hours. Best answer would be to try or half way and take a sample. Been thinking about taking a sample on our vehicles, 8qt sump changing at 7,500 of so miles per the computer is only amounting to 150hrs or less which doesn't seem like much compared to what we do on tractors but maybe thats a gas vs. diesel issue. | |
