2 cycle oil added to fuel and 6.7 liter DPF.

I have been adding 1 quart of 2 cycle oil per 60 gallons of ultra low sulfur diesel fuel in my 3406E CAT and my mileage has gone from 5.15mpg to 5.7mpg. So I added about half a quart with 30 gallons of fuel in my 08 Dodge 6.7 and saw a rather dramatic mileage increase(about 2.5 mpg increase). My question is, will the 2 cycle oil change the burn rate enough to foul the DPF? Please advise.

Im gonna agree with J on this one, I would be leery of anything that is not tagged DPF compliant.

I personally run Supertech 2 Stroke in mine and have no trouble, but then again, I took the blue out of bluetec a long time ago.......

I would agree as well, but suggest a DPF/EGR delete so you have no worries.

Remember though that 2-stroke is designed to burn clean and have very little carbon deposits, especially at the temps and pressures in which diesel fuel is ignited, I think it would be fine. JMO

My Scheaffer's oil rep just gave me a jug of diesel treat, I am going try that. It does say it is low sulphur compliant.

I would think the 2 stroke should be fine. The ash from the 2 stroke oil should be burned off in the regen, especially in the dilution you are using. Again nothing is guaranteed, never done it myself.

I was looking at the Lucas product line today and they have a 'smokeless' 2 cycle oil with should burn completely in the combustion cycle. The 2 cycle seems to really improve the mpg.

Think for a minute..............the system REQUIRES low ash oil.This is just for the small amount of blowby that will enter the combustion process........now you want to burn an oil and run that through a dpf??The dpf has a finite capacity for holding ash.The faster you fill it the faster you will be replacing it.

I believe 2 stroke oil with the tcw-3 rating is a no ash oil so in theory it shouldn't clog your dpf. On the other hand I believe you would get a much better mpg gain if you did the dpf and egr delete.

2 cycle oil in 6.7 with dpf.

I know the ultimate answer is to delete the dpf, However I would like to run it stock thru the warranty period, just in case the Cummins has issues. Probably won't but this is Obama's america.

Question for the day. Who builds the most complete/trouble free dpf delete kit?

The north west has Not banned 2 cycles. I know my bretheren running into California are having fits with emissions. If you are running a pre 2007 truck even with the cleanest flash from Cat, Cummins or Detroit good luck on passing the opacity test.

Sorry that it is tough down there in So Cal. You have some really restrictive standards that are killing production in your state not to mention the overspending on all of the social programs.

If your are a productive citizen relocate to a more conservative state and thrive.
