2-stroke
 

Ordering a new 07 3500 quad cab and was wondering if anyone has any info about using 2-stroke oil in the fuel on these new engines and EPA crap.

Two stoke
 

Friend of mine who maintains a fleet for a local municipality told me to add a pint of 2stoke oil to a tank of fuel. He said it keeps the injectors lubed? I would like some feedback as well.

I love the stuff in my 02 but with all the new emmissions stuff on these 6.7's i wonder if it will make my dash light up like Christmas and screw something up.

I think I read somewhere that its a bad idea in the 6.7l but I do it in my 06 5.9 and it works great .............. 6.7 is a whole different story though...........

Is the only difference noise and knowing it helps keep everything lubed up? Or is there better fuel mileage, performance?

i got about 1 mpg better on my '07 5.9L....it quiets it down some, even though mine is pretty quiet, it also runs much smoother at idle when first starting it up, doesn't feel like its running on 5 cylinders instead of 6...

I'm running 32 ounces of 2 stroke oil to a tank, 35 gals of fuel....seems to be what most people are running with the best results, even 32 ounces is a pretty high (or low depending how you look at it) ratio....less than one ounce for every gallon of fuel...

I think I will start adding 2-stroke oil to my truck too. Is there a certain type of two-stroke oil that should be used?? Elkbow, you still run Polaris?

On the 6.7ltr engines with the DPF....dont do it! The reason behind the CJ 4 classification with the new oil is to lower the ash content so it would not plug up the DPF system. Even though you are running the oil thru the fuel, it all ends up in the same place and causes the same affect. The days of dumping the latest "snake oil" in your tank are long gone.

With todays engines using higher injection pressures and higher micron fuel filter ratings, you WILL plug fuel filters prematurely using any type of motor oil, ATF etc. This is not to say that a suitable diesel fuel additive can not be used since most companies changed there chemistry in order to allow this. However, ATF, 2 stroke oil, used motor oil, and all the other snake oils are a big problem. The price of a complete DPF are not cheap, some in upwards of 3k just for the DPF. Unless you have money to throw away as well as your warranty, stick to a suitable additive.

Almost all diesel fuel additives are designed to help in the lubricity of fuel. As a master tech for a Freightliner dealership, I have seen numerous accounts of the positive effect that Stanadyne, and Power Service have given when used.

Yah, I'm bummed. What am I going to do with all my waste oil now?
My 99' used to love it![laugh]

2 stroke
 

I currently run 10 ozPS and 10oz 2 stroke pertank, do I need to bump up my 2 stroke usage? I also pour my burnt oil back into the tank, I put about 1 gallon in my 54g aux tank and and 1/2 gallon in my factor tank. I have access to oil from tractors and it is a nice thought that your getting $2.40 back of that $8 gallon of oil.......

Good luck with that. Your not doing your fuel system any favors running waste oil. Especially with the common rail.

What is the problem with the waste oil?

The problem with waste oil is that it will plug fuel filters quicker. We are now at a 2 micron filter rating on fuel filters, a hair is 30 microns, if that tells you how small it filters down. This only makes a filter more prone to clogging quicker.

The next problem with waste oil is exactly that, it is waste oil dumped out of a crankcase that has had, heavy amounts of carbon, metal particles, dirt etc.
Why you would want to put that back in your tank and risk the chances of doing harm to your engine is beyond me. Common rail injection pressures inject at pressures upwards of 30,000 psi. This is why fuel has to be very clean before it gets to the injection stage. A small metal particle, or dirt particle in your fuel may not sound like to much to risk, however, coupled with 30,000 psi and you have a major problem likely damaging your fuel system.

What about the waste oil in my auxliary tank? It runs through 2 filters before entering my factory tank as well as being run through a Tshirt prior to being rebottled.
