Diesel Oil.....
2006 Cummins 5.9 - 150k miles. I know nothing about this 5.9 that I just bought, except it really runs good. I've always used Delo 400 in diesel engines, what do you prefer and why? Thanks

Got my filters and changed the oil also.
What procedure do you use to change the fuel filter? Do you flip the drain lever to drain the fuel out, or leave the fuel it in and slowly replace the filter?
Thanks
