Fuel additives - Diesel Forum

renyren · 07-11-2009, 09:39 PM

Hello I just bought a 2000 cc lwb and wanted to know if I should run fuel additives or not? I have read some people run 2 stroke oil but wanted to know if I need to use any and if so what type.

The PowerStroke Supplement to my Owner's Guide says you don't need any fuel additives if you buy good clean diesel from a reliable source. After 10 years and 182,000 miles, mine has seen only one bottle of additive, and that was because it was a free sample.

However, if you live in the ice box "up north", then you'll want to keep a bottle of anti-gel additive in the toolbox. The refinery winterizes your diesel by blending it with Diesel #1 (kerosene) and/or by adding anti-gel chemicals. Only when the refinery didn't expect a severe cold snap would you need to add more anti-gel. Use the anti-gel additive only when a sudden unexpected cold snap is much colder than the weatherman predicted, to prevent your fuel from turning to jello. Jello doesn't flow through the lines and filter very good.

Most components of fuel additives are snake oil, but the anti-gel works. So I'd plan ahead and get one that was just anti-gel and not a lot of other junk included. Stanadyne makes one called "Winter 1000" , but they also make a lot of other formulas that are snake oil, so get the right one.
Winter 1000 - Stanadyne

lubricidity is my concern with this enviro fuel. It is NOT the lack of sulphur it is the process that affects the lubricidity. We just had a big issue with our diesels at work caused by the new fuel and this is a world wide issue hitting those countries that changed over before we did here in US. Big Rigs, Nuclear Power Station Emergency Diesels....all have had fuel system issues caused by low sulphur

So I use Stanadyne Performance....

Do you have data to support that?

Or is it problems from the new emissions add ons to those vehicles that have to use those products?

I've tried the two stroke oil thing, and I generally recognize a drop in my MPG in my data. Seems like some of the guys that report an MPG increase when using two stroke oil have first gen PSD's...and I believe they have a different fuel system. Someone will have to correct me if I'm wrong. I believe they still looped the fuel back to the tank where the later models dead headed?

Try this link to a study on fuel additives http://www.johnfjensen.com/Diesel_fu...itive_test.pdf and make your choice. The best would be 2% SoyPower bio-diesel.

Very familiar with the study.

Here's the chart.

I've used a lot of them. I've used a lot of diesel without them too. And I can still get LSD at my local station.

I recognize that there's a difference in the lubricity, but I haven't seen a study or any actual data that says there's this giant problem with untreated ULSD. Certainly, there have to be hundreds of thousands of commercial trucks running around that have ULSD doing their work over hundreds of thousands of miles on single units. Does anyone have that? I'm not talking about exceptions but about problems that establish a rule.

I'm a firefighter on an Air Force Base. We were forced to change over to bio diesel a few years ago. First problem we had was it loosened the sludge that had built up in the tank and clogged filters. Once we got over that hurdle we started having problems with our support trucks that didn't get driven every day. The fuel seperated in the tank causing anything from poor performance to not starting. The performance drop was noticeable once we changes over. We got a waiver for our fire department vehicles. Once we changed back we noticed the increase in performance. Bottom line for your truck is if you don't mind a little drop in performance and you use your truck regularly bio-diesel is ok. I know this a little off the subject of the original post, but hey I'm on a roll!
