Same filters for gas and diesel use?

[AuthorEditor]

Are there any technical reasons you can't use an ordinary car/truck oil filter originally spec'd for a gas engined vehicle on a diesel engine? Assume the filter fits, is an appropriate size, has the right bypass and anti-drainback features, etc. For example, is either nitrile or silicone for the ADBV a problem with diesels? What about filter media? Is something like the nylon cage in an Ecore filter a possible problem? How about the sealing gasket?

Nope. My dads Diesel tractor uses a popular Honda size, PH3593A.

I think the only difference, outside of some special water absorption filter (or one with a drain integrated), is the micron rating. Some spec different primary and secondary filters and most that I've seen are finer than their lube filter counterparts.

Here's a fuel filter that I use in a dual Permacool setup for my oil fired boiler. I got tired of those smaller sponge/foam/felt filters.

older gm diesels use a PH5 just like the gasser.

Yup, and many tractors spec the FL-1A.

Thanks for the replies. I took a look at the Wix list of applications for the 51515, equivalent to the FL-1A. There were lots of diesel trucks, forklifts, and tractors.

Yep. Oil's oil. It's just filtering it..

VW factory filters often have written on them both a mileage for use in gasoline engines and diesel engine. The mileage for Diesel use is shorter, however.
