fuel additives

Here is another article where they looked at fuel mileage improvements:

I've tried Lucas, Power Source, Marvel Mystery, ATF(works great on a cummins), and 2 Cycle(stroke) oil. What I've notice on my E-model cat, the 2 Cycle worked the best.

 

Same here on my Acert,at least in warm weather.

 

Any of yall ever used or know anything about these mpg caps/crumbs? They seem to work pretty good on gas powered engines:

I've been really unhappy with the mixed results I've gotten with fuel this past winter. My fuel mileage has been all over the map... from 4.3 to over 7 MPG.

I've talked to a few transport drivers who deliver fuel... nearly no one is using a 'winter blend' anymore... around here in WI they use an additive called 'Tundra' that keeps the fuel from gelling...

I have also found that a higher cetane rating will make a difference in your engine running smoother and getting a little better MPG. Most fuels are between 42-46 cetane.. the minimum standard is 40. My son's 600 C-15 CAT can pull 6.1 to 6.1 now that he's using a 51 cetane fuel he buys at a local trucking company near his home. When he fuels on the road his mileage drops to well under 6 mpg.

My Cat runs much smoother on the 'premium' fuel and on a good dose of Power Service... but I haven't seen a big increase in mileage... just about 2/10's so far. The higher cetane fuel burns quicker creating a cleaner burn and the engine starts quicker and smoother in the cold weather, too. The Power Service will jump the cetane about 3 points or so... I'm the biggest sceptic of all regarding elixer in a bottle' but my research seems to tell me I'm on the right track.

I am keeping track of my MPG's real closely now...

I also found on my last trip that the brake distribution valve on my trailer was sticking causing the brakes to drag... now I'll keep checking the MPG to see if there's an improvement now that the valve is changed.

 

I used Lucas a lot of times but I never seen any fuel mileage improvement. Maybe protects the engine in time but for fuel mileage (at least for me) never did any good.
I tried FPPF and I've seen a bit improvement but I did not faint for the numbers. I will keep using this one for a while then I will post the results.

 

I've never used any kind of additive in my car or truck. Never had my fuel gel even when my car sits for 3 or 4 days and it gets to -45 here in the winter. They put all the additives you need in it before you buy it if you check the websites they'll tell you not to use them due to fuel volatility or something like that. A company I used to work at used them (don't know what additive, it was before i started there) once they started blowing holes in the top of the pistons they stopped. Not saying it was the additive that did it but once they stopped using the additives they stopped destroying pistons. Don't know maybe the fuel is different here?

 

does your car run on diesel, too?

it's nice that modern trucks send unused fuel back to the tanks when running... I don't know how big of a difference it is, but I hear it helps a bit with keeping diesel fuel warmer.

 

Yep car is diesel too, sits in the driveway during the winter with an oil pan heater. I've only driven 2 gas powered vehicles in the last 7 years .

 

Another vote for Schaeffers!
Drawbacks are that it is hard to find on the road, and I don't think it has any cold weather protection, may be wrong there.

After fueling at the Loves in Albert Lea Lake, MN; then dumping two quarts of Howes in each 150 gal tank, my truck quit the following morning in Inner Grove Heights, MN (temp was -6*f); on top of a railroad track as I was pulling out of parking area, to enter plant and off load.
This happened the same week I mailed off the final truck payment; all I could think of is "would my insurance cover everything when the train came around that curve?" Train damage, plant damage, totaled out truck, totaled out company trailer, environmental impact, demurrage for all the trucks wanting to enter plant; my heart transplant?......... Another driver ran up with a quart of "Diesel 911", we filled the filters with that and the Shaeffers I had not put in after fueling,(it was too cold!), and it fired up, but was very sluggish. Got it off the tracks, went in to nearby truckstop and bought $154.00 of the Diesel 911, (everything that was on their shelf.)

Learned a couple of things......
(1) Even though it says blended fuel, always add anti gel.
(2) Howes did not work for me, even in the blended fuel.
(3) I don't think a fuel filter heater would be a bad investment.
(4) Maybe this 58 year old coonass, that has been driving trucks for around 35+ years doesn't know everything he should about driving.
(5) I LIKE driving in the south!!!!!!!!!!!!
