6. 7 cummins engine savior
"This filter has the best features of any filter sold to fit this application. It is the only filter I have found that has an anti-drain back valve to prevent oil siphoning out of the filter during shut down cycles. Whether understood by the general consumer, it basically stops dry restarts after sitting for a few hours. Absolute game changer for engine life, coupled with the media filtering out particle size that other brands of filters are not capable of achieving makes this the “gold standard” oil filter for me. This filter is a premium product at a fair price."
