I've done some reading on this, on some of the previous posts, and still can't find the correct answer. My question for the guys adding 2-stroke oil @ fill-ups is this:

How much do you add? I was think'n 1qt per fill-up. Average fill is 20-23 gallons. Thanks

Tye

P.S. I got a killer deal on this stuff, $6.00 a case, (12 quarts).

 

I wrote the last thread on this issue, and everyone seemed to aggree it's ok. Most quality 2stroke oil is a no/low ash type light oil and is allright to run. I have only used it on one tankfull and it was 1qt. of Penzoil outboard oil. I will continue with adding 1qt. per fillup with 1pt. of MMO and hopefully the 1.5mpg increase I noticed over the MMO alone is a prolonged gain and not just a 1time deal.

 

I'm only using 8oz of TCW-3. But I'm mixing it with 16oz of Power Service Diesel Klean.

Last week I filled the truck and added a mix of PS, MMO and TCW3.



This week my motorcycle died.

 

i am using ps and 16oz of tcw3 every tank .

 

Buckshot,

Adding 2-stroke oil seems like a good idea for lubrication but I can't see how it will increase the mileage a measurable amount. When you asked if it was a good idea you didn't say why you wanted to.
Let's say you add a quart per fill up and each fill up is twenty gallons. If you got an increase in mileage of 1 mpg, that's twenty miles extra on one quart of oil. Wow, that's 80 mpg on the oil! Hmmm, how could there be that much energy in the oil? There's not.
I tried running my old 1st gen once on pure lube oil, no fuel at all. It ran just the same as always. Another time, with my Isuzu, I was almost out of fuel and had to buy about a dozen quarts of oil to get me home (late night, no stations with diesel) and again, ran the same as always.
I don't know if the third gens can run straight oil or not, but there is concern about lubricity. And the problem may get worse as diesel fuel gets "cleaner".

And at 10 - 13 dollars per gallon for TC-W3 and about the same for Power Service what are you saving, cummins says no additives are nessesary, what am i missing??

Saving the lift pump, injection pump and injectors.

Fuel mileage is one reason, but mainly because of the low sulfur fuel that were going too in the next few months. My concern is making sure the Ip stays happy. I'm researching for the time being.

It was my understanding, that unlike the 1st gen and early second gen engines, these 3rd gens where designed to run on low sulfer fuel?

I think the lift pump failures are due to design screw ups more than a lube issue.

I'm not arguing the fact just curious.

i use either mmo or non-detergent straight 30 weight oil. you can get this oil at wallyworld for 97 cents a quart.

 

I've adding a pint of 2 cycle oil to a fillup for the past year.Probably should double it huh?

 

Since an additive like powerservice pays for itelf with mpg increase (at least it has for me both in my PSD and my CTD), WHY would anyone make cocktails to put into your tank? It seems like a waste of time, since the fuel additive is essentially free and at the price of diesel now saving money.

Maybe I need to add something else in there because my CTD is so low maintianance I need the extra work just to still feel involved . (mmmmm, maybe there is something I can put in the tranny too, and the radiator.) Sorry, Not trying to flame, but it seems like extra work.
Having said all that, anytime you add lubricity to the fuel system of a diesel you are helping it run smoother-less wear. If it needs that or not is hard to quantify, but a lot of pump failures have been traced to wear/low lubricating fuel. IMO I'd stick with a product specific for the application. Gunked injectors or anything else down the road are a risk I won't be taking.
I am usually pretty open to new ideas and experimentaion, but in this case I don't see any benefit.
Anyway-rock on!

You hit the nail on the head! In Ca. our fuel is already garbage with all the additive and stuff because of the tree huggers. What do you think is going to happen with the low sulfur fuel? I'm trying to avoid any costly and un-neccessary repairs in the future.

I've been talking with a local oil distributor that has bio-diesel fuel additive available. According to them, 2% bio-diesel lubricates better, cuts down on smoke and smells better. They have some commerical only pumps with the fuel, but not public pumps. I'll find the web links and post them. It makes for an interesting read.
