I did after 5K there was nothing different. But I run a bit leaner on the 2 stroke oil. I mix 8oz 2 stroke with 8oz of PowerServe and try put that in at every fill up which is about 25 gals. I am guessing the mixture is about 200:1.

hmmmm... two stroke oils???

has anyone tried this in 12V?

 

Hm....

You sure, I was under the impression that 2 stroke oil was designed not to burn?

Jim

 

There is so much of this I don't understand, but I am thinking that what you are describing is not related to increased lubricity. I am thinking that it is more related to timing. By that I mean the timing of the injected fuel burn rate.

I am basing this on the assumption that as you add more timing, like with a performance box, you get more diesel clatter. And for the most part the opposite is true. So thinking along those lines, I would say that 2 stroke oil slows down the combustion burn rate.

People that run bio fuel or those running motor oil comment about the same thing. But, as usual, I have little clue or personal experience. Sometimes I think we are all pioneers in this.

Jim

 

Semantics here, I think. Yes it's designed to lubricate while it is being combusted ... but it also leaves a film on all surfaces after turned off, if it's a good quality 2-cycle oil. It's specific gravity is almost identical to Diesel fuel (same thickness or weight).

Dieselfan -I think 2 qts in a standard tank is a lot (70:1) when so many are seeing good results with half that. JMO!
(Nice meeting you in Baytown)

i have had a evenrude 60 horse outboard since 1990 , have not ever changed plugs, i use it every summer season

 

Ok... Give you something to think about... a Sthl Chainsaw using mix fuel (50:1 Gasoline / 2 cycle) and I never changed the spark plug in that saw ever... It now going on 12 years old... I cut up to 12-15 cords minimum every season...

 

By Cummins Standards you can burn up to a quart of WEO (Waste Engine Oil) for a full tank of fuel (35 Gallons). Basically 140:1 mix ratio...

So I've been mixing 1 quart of 2 cycle for every 20-25 gallons pumped. So that makes 20 gallons of fuel = (80:1) and 25 Gallons fuel = (100:1) Personally I wouldn't go much lower than the 80:1 ratio though...

Remember WEO has impurities in the oil so it will leave deposits on the pistons, injectors, and valves... Where 2-cycle oil was intended to lubicate and burn off at proper temperature. Also remember that the combustion temperature is quite high these trucks so the 2 cycle will completely burn off.

 

thanks rjohnson, maybe ill cut back to 1qt per fillup since i dont run it dry.
i value your opinion since your in the oil business.
(nice meeting you also and seeing that sharp truck.)

thanks, dieselfan

 

I'm still trying to understand why folks would rather use products intended for other purposes, even though they might work fine, when designed for diesel fuel additives are readily available, perform several other functions and are cheaper.
Is it because diesel additives don't look "oily" enough?
Well get a clue, looks don't mean anything when it comes to lubricity.

 

Ok... That's simple...

What is MMO? It's a light weight oil right? But it lubes the pumps and helps the VP44 and LP... But it can be expensive... But PowerService is getting reports that it has alcohol in it. Not a good thing for already thin fuels. It might help with gelling but it don't help with lube... For some of us in the back country and don't have Wal-Marts (200 miles one way!) close by can't just get PS, or other brands easy...

So 2 cycle is at least clean oil it not WEO... 2 cycle oil is in every gas station around me... Lots of chainsaws and other equiptment used...

 

Cummins allows I believe up to 5% WEO, seen many truckers do this for years, even now some systems continually dump engine oil into fuel, and is replaced by new oil.

I've tore down and inframed a lot of diesel engines, some with WEO(some in excess of 1,000,000 miles-Cat 3406C,E, Cummins M11,L10, N14, and have yet to see 1 that has much or excess wear on liners, parent bore, or excess carbon buildup in head/pistons/injectors.

If you filter WEO before you dump it in your fuel, you will have very little if any issues. 2 stroke oil is even cleaner to burn. Use it and don't worry about it IF you want to. For the average person it is easier to go and buy a bottle or two of additive instead. At least in my mix, I know I am adding a lubricant for the fuel, to combat now more than ever, the crappy ULSD fuel.

 

You got to turn that saw on, Mopar!
That's why it takes you so long to cut a cord of wood!

...Hey!!! What's THAT noise!

 

Wise ___ !!! I gather you seen the pic in my gallery... I can cut 2 cords in about 4 hours. But getting down the mountain takes another 2 hours...

But since I got a chainsaw handy and it needs 2 cycle oil... Why not give the Cummins a bit of a drink too..

 

anyone run 2-cycle outboard oil in a 04.5+ CR ctd?
