I had a 2006 F250 6.0 and would add 1 ounce per gallon of 2 stroke oil when I filled up which made the engine run quieter and added 2 mpg. Truck ran excellent.
Getting ready to pick up a 2017 6.7L and curious if anyone else has tried this to the 6.7L engines?
Not on the 6.7's! These arent like the older diesels where they would burn almost anything. the fuel delivery system is way too sensitive to be adding much besides what Ford recommends, and a few others(stanadyne, power service, optilube).
Thanks for the response, if I remember right the 2 stroke oil was tested against some larger brand name additives (on the older 7.3 and 6.0) and came out with better performance.
New engine is too expensive to risk any damage and still under warranty.

That test was done in 2007 way before the 6.7L engines showed up.
Be safe and use products that are recommended. I'd shy away from gypsy cure all and other heard from a friend ideas.
I have been using 2 stroke in my 6.7 since new. I run Amsoil Interceptor or Dominator depending what I am doing that weekend. I also use the Amsoil diesel treatment. What ever you chose to run ensure that it is ashless and smokeless. At 75k miles on a 2012 I have had no issues with the DPF, engine runs quieter, do see mileage increase when added. Of note if I add 2 stroke a quart every fill up on a long trip, I see regens about every 1500 to 1800 miles. On the same trip if I stop using 2 stroke my regens happen between 900 to 1100 miles. The last thing I noticed is that the regens are shorter when I have a tank of mixed fuel.
I normally run a quart per about a 33 gallon fill up which is roughly a 125 to 1 ratio. I did run an experiment with a larger amount but found little to no benefits for the higher mix ratio. How much? Let's just say over 1 gallon or about 30 to 1 ratio. It made little to no differences in mileage or regen frequencies after doing it. Realize that 2 stroke oil is made to burn and lubricate. So at 4.5 years and 75,000 miles you decide.....:winking:
I don't have alot of idle time so not worried there but here is something to think about...one of the bad things of idling a diesel engine is that combustion temps tend to dropoff and we get piston wash. With 2 stroke oil you get two benefits. First and I can't prove this but I am going to bet you get a higher combustion temperature then just plain diesel. Nothing significant but an increase. The other thing is if you do get a piston saturation you do have a bit of oil residue being left behind.
The number one reason I do it is because here in Alaska we run #1 diesel or winter fuel (Not Blend) for months. Need the lubrication.
I have other trucks running the 2 stroke additive. Started using the mix on my old NA 6.9l, have a '00 7.3 with 205k and a '03 7.3 work truck just getting ready to hit 300k but still running strong. Both of my 6.0's never any issue with the variable vane turbos, I skipped the 6.4's but neighbor runs his welding truck 6.4's on the 2 stroke as well as his diesel welders.. I do have another 6.7 work truck with 210k that just went down the other day, believe it has a rod bearing going bad, hearing a single knock and the driver was not easy on it. All of these engines have run 2 stroke oil basically since new.
Archoil's AR6200 is a good fuel additive that promotes combustion, cleans the fuel system and adds lubricity. It is not a cetane booster so it can be used with a cetane booster like Opti-Lube Summer Plus, one of the best from the 2007 study.
Last test I saw a few years back Optilube
I use Stanadyne, Ford PM22, Liquimoly,2 stroke oil. Whatever I can get my hands on
