That study got a lot of attention last year at TDICLUB. It's quite good, but lots of people still think they are getting something for their money with the PowerService products. The anti-gel properties are useful I guess, but it will not cover for low lubricity fuel. If I have no biodiesel, I will mix some low ash two-stroke oil (TC-W3) before one of those marketed snakeoils.

Why does the study say that the TC-W3 is not ULSD compliant? I’ve also heard that the TC-W3 does not mix well with diesel fuel, therefore eventually separates itself and settles to the bottom of the tank. Any thoughts? Wal-Mart’s Tech brand is sure cheaper than using Power Service.

Don't know if using two-stroke oil will plug a dpf. That's why they say it's not usld compatable. I also have a hard time believing a lubricity formula does the opposite.

In one of the other threads, there was a discussion about ZDDP being removed from oils. It could be that TC-W3 contains this. Most of that discussion focused on the zinc and phosphorous aspect. ZDDP is actually zinc dithiodiphosphate. The "thio" means sulfur. This is conjecture, but it could be a potential reason for it not being ULSD compliant. Since we're all (us U.S. guys) are pre-2007, we should be good to go.

I'm not sure why 2-stroke oil would have issues mixing with diesel fuel. Chemically, the two are similar. The hydrocarbons are just bigger. It might be the additives in the 2-stroke oil that separates out, though again I'd be surprised that there's that much difference. The base oil in the 2-stroke should mix in without any problem. There also could be a volume issue here too...people could be doing something like mixing in a can of the 2-stroke in a small amount of diesel fuel find that it's on the sketchy side of things. In a larger volume, like our ~20 gallon fuel tanks, it's probably less of an issue.

I stopped using TC-W3 after a certified Cummins technician told me that they’ve had to clean many customer’s fuel tanks due to people dumping used motor oil into their tanks. He went on to say that the TC-W3 has the same effect, meaning that there is nothing in the tank that is keeping the oil and diesel mixed, therefore it eventually separates and settles to the bottom. Obviously there is a big difference between pouring used motor oil into the tank versus fresh TC-W3, but according to him, the TC-W3 does not completely mix with diesel fuel.

This is so funny!!!!!!! To say 2-Stroke fuel oil will not mix with diesel and will eventually separate is a joke. Do yourself a service and simply get a clear jar of diesel and mix in whatever ratio of 2cycle you want...........let sit on a table for a few days...........months if you want!!!!! And report back what you find out!!!! Also, its a joke to say there is nothing to keep the fuel mixed up.........every diesel I know of has a return fuel line that goes back into the fuel tank. Therefore your fuel constantly recirculates, keeping everything mixed real well.

ULSD mixed with WMO in my catch tank when I was installing my external lift pump. I could not detect any seperation even after several weeks... The ratio was probably close to 1:1. IIRC, it did thin out the WMO quite a bit.. However, the WMO was stored in a cold garage during the Winter Months (ie low ambient temps, low viscosity).

Cheers,
Erik

How much TC-W3 do people mix per 20 gallons of ULSD?

Thanks,

16 oz per full tank in my case - study quoted 16.64 oz per 26 gallon tank.

Anything less than a full tank, I just fudge it and add 1 oz/gallon more or less.

The tested ratio is 1:250
