So I'm due for a change and I'm wondering if anyone is running the Lucas engine oil in their psd.. I've got a buddy that sells everything Lucas and he swears by the stuff. Just wondering if anyone is running this stuff. He suggests to run the 15w40 magnum high tbn ci-4 oil because it if formulated for pre 2007 diesel engines.

I've run this in my 1st gen cummins I used to have with a zinc additive and loved it but wasn't sure about running it in my psd. He says he's got guys that have switched from rotella and loved it but I'd like some first hand experience.

 

Never have run it but this will give you a bump.

 

my opinion is that it is all marketing, just like spamsoil.

if it was that god almighty good, ford would be using it.
they don't so i don't.
