Best Adds for Diesel Fuel?

[Strjock81]

I have tried pretty much everything in my Cummins and Powerstrokes, and can't tell a huge difference, but notice quieter engine, no smoke, and a slight economy gain, and I like the idea of the extra lubricity. Never could tell a seat of the pants difference.

Our 01 TDI shows a lot more improvement with different adds, like Diesel Kleen.

Everyone on here preaches FP, but it isnt a cetane improver, and does it offer anything more than what the other adds like Stanadyne and Diesel Kleen do?

Terry has told me to try FP instead of the other adds I was using, including Neutra, Diesel Kleen, etc.

I want to try something new like Primrose or FP, and always thought FP was the cheapest add on the market, but primrose 405 is actually cheaper than FP per gallon of fuel treated.

There are so many different diesel fuel adds out there, and the more I read the more I get confused. Which direction should I go?

What is wrong with the Schaeffers Neutra?

I think you should try Schaeffers

#139 SoyShield Cetane improver. Contains fuel economy package. Cummins L-10 Superior Performance. Upgrades #2 to Premium. Improves lubricity with soy oil. 1 gal. to 500 gal.

I personally liked rotella DFA. It gave measurable results that others, including redline did not.

Im curious to try chevron delo additive... It has similar consistency and smell as DFA, if I recall correctly.

If it's commericially available near you, bio-diesel is probably the least expensive additive you could use. With current fuel prices, it's cost is now about the same as petro-diesel fuel.

A mere 1% blend of bio-diesel in petro-diesel will increase lubricity 65%. It's cetane index is higher than petro as well.

I'm currently running a 20% blend of bio in my Dodge/Cummins, mixed with Amoco Premier(minimum 50 cetane)Diesel fuel. The engine runs smoother, quieter, and no visible smoke from the exhaust. Fuel economy is slightly better.

Or simply search for premium diesel fuel in your area, such as from Flinthills resources, http://www.premiumdiesel.com

No aftermarket additives are necessary using this stuff.

Gotta go along with that. Schaeffers is the chemistry behind their premium. or

With 20% bio only, you will indeed get the lubrictiy, emission reduction and cetane improvement, but lose some hp/mpg. By adding the Chevron premier ( great fuel) or schaeffers soyshield/Dt 2000 you get the mpg improvement, corrosion inhibitors,detergency pkg, moisture control and injector cleanliness as well.

You may also consider a little 2-stroke engine oil if lubricity is your main concern. Dont think itll get cheaper than that.

When I looked into diesel additives it seemed that lubricity was the most important attribute as they're changing diesel fuel composition in the US for emissions, and it was poor quality to begin with compared to Europe. Next is lowering the gel point for winter use, and finally cetane improvement as US fuel is kind of low. Stanadyne has all three attributes and they appeared to be the only diesel additive that had OEM approvals, and they apparently make the stuff that Ford (GM too ?) uses. But, whatever is at Walmart is going to be popular.

Some are using Marvel Mystery OIl and ATF, and while I wouldn't use ATF I'd look into MMO for the lubricity and combustion chamber cleaning that it seems to do.

I've tried a variety of additivies and it seems that my Kubota 32 horse likes Stanadyne the best.

For our cars/trucks (gas) it's FP.
