So I've got a stupid question. A lot of Isuzu Trooper owners run diesel oil (Shell Rotella) in their vehicles. They do this to slow down/prevent the way our engines burn oil. Right now I am currently running Pennzoil High Mileage. However, I have begun burning oil. I noticed about half a quart gone after five hundred miles. I am going to continue running Pennzoil for the time being until my oil burning gets worse. So here's my question. I am going to buy a bypass oil filter setup (probably from Pennzoil unless someone can suggest a better/cheaper kit for me). If I switch to Shell Rotella or a similar diesel oil. Can I run it through my standard Isuzu Trooper oil filter...AND can I run the diesel oil through the Pennzoil bypass filter setup if it is intended for a trooper running on regular gasoline engine oil?
