Diesel and 2 stroke oil

Ford_6L_E350 · 07-12-2008, 09:49 AM

From another website I was informed that specific 2 stroke oil will help lubricate the injectors on a 6.0 diesel.

It has to be TWC3 oil, as it burns ash free.

So, I tried it on a 5000 mile trip.

The mileage was essentially unchanged (16.43 for the prior 48K miles and 16.47 5K miles later. The power was the same to the seat of my pants. But, the engine seemed much quieter, especially at cruise. I really couldn't hear the engine, but I could hear the stock exhaust - it actually has a nice sound when you can hear it.

Would the lubrication have prevented the two injectors failures I had in Alaska? Don't know. Will it prevent future injector problems? Don't know. Will I continue using it? Probably, I bought another gallon from Wally World.

Anyone else ever tried it?

I have found a similar result from running a small amount of biodiesel in the tank. This has the added benefit that if your run less than 5% you also don't risk voiding your warranty. It is really amazing the difference it makes in engine noise. I would estimate about a 25% reduction at freeway speeds.

Mike,

There's a lot of discussion of 2 stroke oil over at TheDieselStop.com. Is that where you found the info?

Haven't tried it myself, though what I've read it sounds promising (as does the B5 biodiesel). So far, I just use Stanadyne Performance formula.

That is where I first ran across it.

It does make the van quieter when it is running. And I can't seem to find any negatives - maybe the $12/gallon - to be added to 128 gallons of diesel. It was a real problem when we had 2 injectors fail in Alaska. We had to drive well over 1000 miles to find a dealer who had injectors and could fix it. 5 days in Prince George, BC might be nice under other circumstances but not with the van in a shop. The PG Ford dealer was great, we just hit a weekend and the diesel technicians days off. And the 2nd bad injector wasn't noticeable until the first one was replaced - then he had to tear it all apart again to get to the 2nd injector. If it will prevent an injector failure, it will be worth $12/2000 miles.

So what do you do, just throw some in before you fill?

My typical fillup is 30-35 gallons. So, I just add one quart (32 oz) then fillup.

According to the Dieselstop discussion, it is very important not to use the other kind of 2 stroke oil, only the TCW3 or TCW III. I earlier called it TWC 3, when it really is TCW 3.

The other kind of 2 stroke oil will make ash and problems for your engine. If you want a technical paper on the 2 stroke oils see:

The discussion comes from JetSki's since most of the 2 strokes are used in those Personal Water Craft.

Well? Did you give it a whirl? I was going to try it for a work trip last week, but the farm store only had a sny blend. It was TCW III, but wasn't sure if syn was a no-no. So, threw in half a bottle of Lucus Oil Diesel injector lube/cleaner. Only thing I noticed was my wallet was $10 lighter. My 7.3 is still as loud as a locomotive.

I would like to run 2-5% BioDiesel, but it is not easy to find and then I have to carry it with me on our travels. I carry a gallon of the 2-stroke oil and an empty quart jug. 1 oz/gallon of ULSD. I could do the same with BioDiesel, but I would have to carry more of it - 2.5-6 oz/gallon.

The only difference I've noticed on the 6.0 is quieter injectors. The diesel rattle is still there. But, it does get quiet at cruise.

I'm going to grab a gallon next time I'm Wal-Hell and give it a try. Thanks.

I think all TCW III oil is synthetic.

Check the technical paper:

http://www.sea-doo.net/techarticles/oil/oil.htm

Buried in that paper, it strongly implies that all TCW III oils are synthetic. And, as long as it meets the standard, it probably doesn't matter.
