The cheapest stuff I can find!!!!! Which is the SuperTech Outboard 2 stroke oil in the blue 1 gallon jugs. About $8.00/gal although it was cheaper over the summer.

 

I got some castor 927 left over from dirtbike days. I believe I will try it

 

I don't know why I keep voicing my opinion on this but why not use a good fuel treatment? The stuff that is bottled by mopar that we sell specifically says on the bottle "increases lubricity", as well as a lot of other stuff. HPCR Cummins engines are too complex to pour just any old stuff in, in my opinion. I guess I am just old fashioned, I put two cycle oil in my chainsaw, I put diesel fuel treatment in my diesel, ATF in my automatic transmissions.

 

If I can't convince you, why don't you just look up the MSDS for your particular favorite brand of diesel treatment. You may be surprised at the ingredients. Like I said earlier, mostly SOLVENTS!!!!!! But these solvents do increase the cetane number of the fuel. Any lubrication ingredients added are miniscule at the quantities that they recommend that you add said product to your tank. At my dosage of 2 cycle, it's roughly a 128:1 ratio. That's pretty lean by 2 cycle engine standards as my 50hp Evinrude calls for a 50:1 ratio. I can remember 30/40:1 2 cycle engines also!!

 

Supa,

It's pointless to try to convince someone that 2 stroke is a good idea. If they are skeptical, fine. You and I know that diesels are very tolerant of different additives or fuels and this is one thing that may save them from damage caused by the new fuel. Two stroke oil is the obvious choice for added lubrication. It can burn in a very high performance gas engine and provide ALL of the lubrication for that engine at ratios clear down to 100:1. And burn clean! If someone simply wants to increase the cetane rating, or play it by the book, fine, let them, no biggy. Time will tell if the new fuel is worthy or not. I think part of the concern stems from having little experience with diesels or relating them to gas engines, where additives are not a big part of the game. Eventually, we'll have enough time with the new fuel to find out if it is OK or not, and the "no additive" group will be a nice baseline for comparison.

My old 1st gen, my Mercedes, my Isuzu NPR and my Perkins would happily burn very old heating oil, straight lube oil, or filtered crankcase oil. My common rail has had a much more conventional diet, but 2 stroke oil is a no-brainer. Especially considering the new mandated fuel. And 128:1 seems like a nice ratio. Just enought elixir to help it out. Not so much that it becomes too expensive or a hassle.

So I am new owner, 3500 miles. I am currently using PS with very fillup. Is it a good idea to add the 2-cycle then?

 

Dump the PS and go straight 2 stroke IMNTBHO!!! Go online and find the MSDS for PS and other "diesel treatments" and look and the ingredients!!!!! Would you dump paint thinner in your tank???? Probably not!! But that's what much of the content of these products are.......naptha, xylene, mineral spirits. All are considered solvents and/or paint thinners. ULSD is very dry and solventy. Why would anyone want to make it moreso???!!! 1qt per fill up of 32gal is the equivilant of a 128:1 ratio give or take a bit. This ain't rocket science here people; the only reason we're adding this 2 stroke oil is to lube the fuel system due to the dry fuel. Any increase in mileage is a bonus. Another bonus is that the 2 stroke oil is usually cheaper than any of these "diesel treatments"!!!!

 

Hi all, Im a NuB 2 and I've been doing alot of readin and researchin and I've been readin about this mix of 16 oz of "Power Service Diesel" and 8 oz of "Marvel Mystery Oil". What do you guys think of this mix?

 

It's been said that a premium 2 stroke oil is good enough to run in the crank or even in the transmission. I haven't used it in my Cummins but I will if MMO and/or Power Service is not available.

 

danc46 are you using the 16/8 mix of psd and mmo?

 

I love the smell of castor in the morning!

 

I added 2-cycle oil for a few tanks a while back and it made my truck "gasoline" quiet.

I haven't added anymore because I noticed that I have a slight hesitation (when just barely feathering the throttle). I wasn't sure what caused it.

Will running 2cycle in every tank clog the injectors?

 

I'm using a 50/50 mixture. I usually add 8 to 12 oz when I fill up the tank. I've yet to run more than 2/3 of a tank before filling up my 06.
I'm about to try some of the Howes Meaner Cleaner mixed with MMO at the same ratio. I'll watch my MPGs closely to see if it is better than the MMO/PS miixture.
With 2100 miles on the truck, I'm getting 15.5 to 16.1 no matter where I drive. It's been that way since my second fill up and use of the MMO/PS mixture.
All I can say is that the MMO/PS does make your engine quieter. And my 06 compared to my 2000 is like comparing a pellet gun to a shotgun where noise is concerned.

 

i use Stanadyne performance all the time with good results. But 2 stroke oil, just don't want to see the check engine lite due to a sensor getting messed up. Don't know if Cal has more smog sensors or not.

 

I thought MMO for lubrication plus some PS for cleaning/fuel economy was the hot ticket.... or was that last month?
