I hear alot about guys adding 2 cycle oil to help clean the diesel fuel and for mpgs. Has anybody done this and has it let to any problems wih injectors or anything else? Also what was the results as far as smotther running engine and mpgs increasing? What kind of oil(be precise please) and how much do you add? I have a 40 gallon tank....tell me what yall think and how it has hurt or helped you!!!!!!
I had read on here about adding 2 cycle oil and started doing so last fall. One once per gallon of the walmart oil. I feel it has quieted the injectors down as it replaces the lubrication lost when refining the fuel down to ultra low sulfur. I have had no issues to date and will continue to add at fillups. I thought I had read it was bad for the emmisions on newer trucks. Currently I think I am around 17 mpg. I should be filling up this weekend and will know for sure.
I used to run it in my 99 24v Cummins. It helped the mileage. Gave me about 2 or more mpg better than anything else. I am running very low on my Schaeffer DT 2000 and was wondering about 2 cycle again. I was running Valvoline Multi-purpose and running at a quart a tank, which was 38 gallons or so.
Remember, I was running a Cummins, but.......I ran it a year or so, so maybe 20-25k miles? No issues. Switched to Schaeffer Diesel Treat 2000 after that. Got much the same mileage and the jug was easier to store in the tool box. I don't give a rats azz what anyone says about the mileage...my calculator didn't lie to me.:doh: It easily gained at least 2mpg on a Dodge Cummins over straight diesel. That was pulling 10k in the hills, too. Have yet to try it on the PSD I am running now. I will say this...the Schaeffer isn't doing as well with the PSD as it did with the Cummins. No mileage difference at all. Transmission fluid did as well or better, IMO. Its quite possible the two stroke won't react the same as it did in the 5.9 Cummins. My CAT and M-11 Cummins didn't really care for it either.
I'll try it soon. I have a trip coming up where I can run two back to back and compare the mpg's and everything else. Probably go down with Schaeffer and come back with the two stroke. I'm not going to hold my breath, though. Even when new, my PSD's never got as good in the MPGs as my other trucks.
Cost is another consideration. Schaeffer DT is costing me less than 2 bucks a fill up. I haven't priced the oil of late, but I would bet its going to be more.
I will probably just run it like I do the trans fluid. Half a bottle in the front and half in the back, full quart total. Mine is 38 gals., so I don't see an issue with a full quart in yours. Couldn't hurt to try anyway. Yes, its ashless...TC-W3. As long as it conforms to that spec, you are good.
Not to be an a$$ but I have forgotten more about 2 stroke oil than you will ever know. As for dumping a 2 stroke oil in your fuel go right ahead dumping random things in your tank if it makes you sleep better at night.
Diesel avenger what's ur results on the tranny fluid I know I have heard my grandpa use and he is an old school mechanic but he has had a stroke and I don't think he remembers much since that was 20 years ago since he last drove his big rig and worked on anything
I've been running 2 cycle oil for nearly 3 years with my 190cc injectors and the truck runs and idles smoother with it. I use a mixture of 2 cycle and opti-lube XPD in every tank now.
I use the 2stroke oil with every fillup at just under an oz per gallon. It made an almost immediate change in teh clackety clatter of the engine to a much quieter smooth sound. The change in sound from the addition of this lube tells me that there was a lack of lube in there. It is not for mpg, makes no difference there. It's for lube of diesel fuel system with all of the parts that depend on fuel for lube.
I've been running the wal mart tcw3 2 stroke oil in my 7.3 for probably 50,000 miles. No MPG improvement at all, however it does quiet the injectors down so that tells me it's putting some lube back in the fuel, and for 10 bucks a gallon it's worth it to me. And I have not seen any issues with my fuel filters, but I use 1oz pr gallon or a little less.
Diesel Power did a test that showed a mileage improvement using TCW3 at 1/2 oz per gallon (I don't have a copy of test but I think it was 2 mpg).
This test show a big improvement in lubricity over LSD fuel. In my opinion, more lubricity = less friction and wear. Potentially that should equal better mileage.
I have been using TCW 3 oil for a couple of years and my stuff runs quiet and has not blown up. Don't know about mileage, my 550 doesn't have the gearing for good mileage.
I just started using tranny fluid about a week ago and right away I seen a mpg gain like 2 mpg better and alot less clater and I have a 7.3 turbo idi so it's sounds almost like a car next fuel up I'm going to use the 2 stroke oil and see what it dose I just need the ratio on how much to use
everybody i hear is saying 1oz per gallon of diesel
