Failed my CA SMOG

If your truck exhaust stinks its Injectors. Most CR are very clean,We leave them run in the shop all winter long, No smell Are you share its not the breather Tube getting into the Cab?

This truck came without a CAT, it smelled like a old tractor from mile one. I base my comparison with trucks with Cat, like my brother and dads trucks.

Well I guess its the MN Bio Diesel,You do get that smell form Certain oil when fresh,it does go away after time and Miles.

Maybe thats it - I can't get a tank without 5% bio.

I use no bio-diesel, but I do add 8 oz of 2-stroke oil to the fuel tank at fill-up.
