What does everyone use? I use this http://www.powerservice.com/dk/

In the gray bottle.

I use Howes. In every tank.

I don't use any, I think it's mostly marketing and snake oil.

Been using a quart of TCW3 two stroke oil per tank. The only additive I have come accross that makes a noticable difference. I have uses the Power Service anti-gell in winter.

I do to, I use the super tech brand 2-stroke from Wal Mart. If you use 2-stroke it has to be the TCW3 ashless formula as mentiond by LongRanger. I use 1 ounce per gallon for lubricity unless I can find B2 whivh is a 2% biodiesel blend and that has been shown to provide the most lubricity of anything on the market.

The guys over on thedieselgarage.com pretty much like opti-lube. http://www.opti-lube.com/ I have used it and really like it as well. It does give me a little better mileage when towing the Ranger Z-21. There was a paper written up on different lubes and it showed the opti-lube to be the best.

Power Service, gray bottle, and 1oz/gal ashless two-stroke (I use the injected oil)

this link is probably one of the best (and most exhaustive) studies on lubricity for diesel fuel and will address some myths....

Yep. That is the study I was thinking about. Thanks.

We don't use anything in our trucks. No fuel related issues.

Redline and Power Service.

I just use plain ol regular gasoline...........cause I got rid of my diesel.

you might regret that if you intend to pull around an offshore boat.... Rack storage is great (BTDT), until you either need or want to upgrade or repair engines, drives, tunes, interior, steering, blowers, exhaust, .............

I've decided not to get that 40 footer.

Right now I'm looking at a 24' Baja bowrider with a 496......a bit more of a family boat.

When they get older I will get my big ride.

not a bad idea- we have ski boats here and in Canada and a cruiser for the Mississippi River right now- we took the 5-year-old out for a ride with a friend on a Top Gun on Lake M and she didn't like the noise and the speed all that well. She'll have the need for speed in due time. We're taking a short break, but we'll have another, most likely another Thunder or Cig. I think you'd do fine with the Baja- I've never owned one, but the folks that I know that own them seem to like them. Too bad they went under- Fountain has the rights to them, but no firm plans for reproduction as of yet.

Never heard of using two-stroke oil as a diesel additive. I like the write up on Diesel Place. It said that using the TCW3 was not ULSD compliant. Does anyone know if using that gets you anywhere near pre-ULSD mandated fuels?

near as in what? lubricity capability? Using a high-quality ashless TCW3 2-stroke oil will help replace the lubricity lost with ULSD, but as mentioned before and in the study, biodiesel is one of the best. I've used 2-stroke in the 7.3PS diesels and TDI's I've owned, lots of towing miles on the Fords, both pre and post ULSD without any trouble at all. I've also used it as a lubricity additive when burning JET-A, both in the Fords and VW TDI.
One of the first places guys have seen problems with ULSD, at least with the Ford PowerStroke 7.3, is in the fuel filter bowl and drain 0-rings starting to leak/crack.

I'm pretty sure they are referring to trucks that have all of the emissions crap on them and have to burn ULSD only. I've been using 2-stroke with great success for quite a while now but I drive a dodge with a 12 valve cummins.

As for lubricity, the number one thing you can put in your vehicle is B2 if you can find it. Be prepared to change a fuel filter though if you haven't done it in a while, that bio diesel seems to clean out the tank and fuel system

We don't have bio diesel, so I put a quart of two stroke oil in every once in awhile. My 06 is pre smog crap, so no problem running the two stroke oil.

I'm partial to changing out the fuel filters more frequently than the vehicle maintenance schedule calls for. Cheap insurance!

Just curious, why use both? Cetane boost and anti-gel with Power Service and more lubricity with the 2 stroke? At 1oz/gal, why use more than the study recommends? Which 2 stroke oil do you use?

I just bought my first diesel pickup yesterday....2001 F250 CCSB 4WD with 7.3 PSD so I'm new to this stuff.

TCW3 Ashless oil, Academy has the Citgo at good prices.

Yes they do. Saw it in there for $9 and some change per gallon. Good price to stock up.

Thanks for the heads up but Citgo is owned by the Venezuelan govt, i.e. Hugo Chavez, so I won't be buying any of that.

Been using the Stanadyne performance formula in my chevy.

I'm using Delphi now. Also have used Stanadyne. The performance diesel shop that works on my truck said to use something other than PowerService.

How does using additives affect the warrenty on all vehicle engines? I had a '96 250 ford diesel and the owners manual said in several places not to use additives.

Today isn't the same as '96. In the mid 90's diesels had different injectors and fuel delivery. They were smoky things that didn't make anywhere near the power of today. Back 15yrs ago there may not have even been decent additives available. I've read about people using all different kinds of crap for additive, including gasoline. In '96 diesel fuel wasn't ULS and I don't know if it was even low sulphur. Can't speak about Ford or Dodge, but certain additives are approved by GM.

According to the service guys where I bought my truck Stanadyne is one of them.

It was the Chevy service dept. diesel guy who first told me about Stanadyne.

The service shop I go to recommends the Standyne as the best.Unfortunately that is the only place that carries it locally and they charge straight MSRP, plus some I think.
I have a 1998 &1/2 Dodge, 100K onit, and I use Power Service most of the time, with some Marvel

for the most part all addatives to fuel or oil are snake oil period. Now if you live in the North like I do you have a case for using Mobile 1 synthetic oil in your truck. It gets down to -40 up here and we plug our trucks in. Mobile 1 or other synthetic is the only way to go

Mobil 1 or any multi-vis diesel-rated synthetic is a very good idea for very-cold climates



a re-post for those that didn't read the whole thread or haven't ever read this scientific study on additives to ULSD fuels.
I'm definitely not in agreement with the 'it's just snake oil' theories. Additives can make a BIG difference in injector life for the older diesel engines that weren't designed for ULSD. When the lubricity is decreased or removed (like sulfur), you have to do something to replace it, or guaranteed you'll pay big time in engine parts down the road.
I knew some pilots who ran JetA in their trucks or VW's with no additive (they had the 'snake oil' attitude), and their engines puked in less than a year. Wouldn't listen to us mechanics about the airplanes, and they wouldn't listen to us about their diesels. Such is life......

Yup,

I'll continue to use my snake oil, thanks. With almost 200k miles on my original injectors & pump, no fuel related issues, I like my odds......

Unfortunately ULSD is rat pizz, so it needs a little snake oil, or two stroke oil, or something.

190,000 no additive on last diesel. 50,000 pulling 33' fifth wheel w/no additive. Neighbors diesel 212,000 no additive.

Just can't see a reason for additive unless it makes you feel better inside. I do change oil every 6-7000 miles.

The company I work for is of the same opinion and we burn 1 million gallons of diesel fuel - per day.

Buy it from places all over the US too.
