Default Diesel oil in your jk

A friend of mine has a honda goldwing. He told me by putting rotalla diesel oil. I don't know what weight. I assume 20w50. He claims his shifts are alot smoother. He changed the oil in the pan not the tranny fluid. Anyone heard of this being done? Would something like this work in the jk? Now i gotta tell ya when he 1st told me about this diesel oil swap. My internal bullshit meter registered about a 9 on a scale of 10. I am not going to do this on my jk. I just wanted to know if it could be done in theory.& until the replies come in.

The oil in your crankcase has nothing to do with your shifpoints or how your tranny shifts. However there is nothing wrong with running a diesel grade oil as long as it is the correct weight.

Not on dirt bikes but yes in his gold wing. You will RUIN the clutch on a street bike by using automobile oils in it. I work at a motorcycles dealership and have had bikes for more then 20 years. Diesel oil is 15w40. Run the oil that the manual says to run it it , the made the vehicle after all !

Putting 20w50 Rotella Diesel oil in your JK is a really bad idea. That stuff is cheap junk and full of paraffin wax and other garbage you don't want plugging up the galleries in your motor. Use a synthetic oil like Mobil 1 or Castrol in 5w20. Can't believe anyone would even consider this let alone create a poll about it...

Wow, didn't know that about motorcycles either... I learned something today

BTW, generally diesel oil's have much more advanced add packs than regular "gas" oil's do.

To learn more than you really want to know about oil you can visit www.bobistheoilguy.com and spend the next 2 months reading.
