2 cycle oil and EGR do they mix?

[Stakk]

Many are running about an once/per gallon of diesel of 2 cycle oil in their rigs for lubrication, will this cause the EGR valve to coke up quicker in the 6.0's or does it not effect the EGR valve?

Since the TCW-3 is ashless I would guess there isn't an increase in soot or carbon. I have the EGR "non-operational" with my SCT so I can't say for sure.

Thanks, it sure runs smoother and quiter with the 2 cycle in the tank

[HeavyAssault]

Sure does....

I unplugged my EGR and gutted my cat......been running it for about 8000 miles, no problems, been getting 17-18.5 mpg....... after reading that unplugging the EGR makes the turbo spool less I hooked it back up and yes, the turbo spools up about 5-7psi more, runs a little better. I want to run it with EGR plugged up to see if it does anything to mileage.......2004 model 6.0

Are you running oil with your fuel or just doing an eval on how it runs with the EGR hooked back up?

both, I alternate between 2 cycle and Diesel kleen every time I fill up, want to see whast happens to mileage over the next 5000-6000 miles

STAKK, did u hut the cat or remove it with a cat delete, if gutted how did u go about doing it

[Stakk]

Removed the cat, used a 5psi hammer and steel bar and went to work, inside looks like a cros between screen door and steel wool......... beat everything out put back on

Fuel mileage dropped to around 16 mpg with the EGR plugged back up......unplugged and filled up two tanks worth, mileage back up to 18.3mpg
