fuel additives

[yellowcat]

Was reading a write up about a fuel additive called rxp generation ii. Anyone ever used it before. Sounds like this one my actually work. Just tired of spending money on the stuff that is no good.

I've never used this rxp generation ii, but it sounds to me like an octane booster, in that it burns hotter and cleaner and burns off the byproduct emissions. The rule I'd always heard about octane boosters is that one tank full of premium gasoline per month will do the same thing and keep your injectors clean.

What you have to decide is whether it's cheaper (nowadays) to pay for a tank full of premium or pay for a bottle of octane booster. Even the cheap STP octane booster will do the trick once a month, and it's way cheaper than the $6.99 they're asking for this new stuff.

Just my take.

Using premium gas with a stock explorer is a waste of money. If you want to keep your injectors clean use an injector cleaner one a month.

The best way I have found to burn carbon out of the engine is to run high RPM for about 5-straight minutes.

Why don't you give it a go and let us know how it performed?

I actually have had great results with the lucas fuel injector cleaner its a bit thicker than most every thing else out there just make sure to put it in the tank before you start filling it up so that it mixes well.

I have found Fuel Power Plus for Gas to be very good.

Ditto.

What kind of results did you get? I searched the forum for "Fuel Power Plus" expecting to come across one of your long and many threads. But I got zero hits.

The only additive I've seen definitively boost mpg is Techron. But it's expensive and short lived. On the other hand, I have found that the amount they put in their Chevron/Texaco gas provides just enough increase in fuel efficiency to justify the 4-6 cent extra cost over cheap, generic gas.

Hard data is not available yet. More testing is underway.

I have yet to see any mileage difference form any of the major gas products ( BP/Amoco, Texaco, Mobil, Shell, Chevron ) and I have tried them all.

and not likely to here in the US unless you encounter winter gas. With the exception of high alcohol formulations and winter gas the energy density is very consistent due to the specifics of what federal regulations have decreed qualifies as highway gasoline. Again, with the exception of winter gas and high-alcohol content, the only differences are going to be in the areas of lubricity, detergency, and purity. To identify differences between brands due to lubricity and detergency you may have to drive 10,000 or 30,000 miles on each brand. For differences in purity, stick with one particular station for 5,000 to 50,000 miles.

Once you leave the states things get totally different. There's a whole other world out there.

I look forward to your results.

Interesting. I doubt I'm encountering winter gas in Alabama. But I could be erroneously generalizing my observations. I knew all gas in my city comes from the same depot, so I'd switched to cheap gas. But I also knew the additives were different between brands. When I ran a bottle of Techron through and saw a noticeable mpg gain, I began to have second thoughts. So I decided to test things. My comparison was made between a Wal-Mart gas station and a Chevron near my home. They were built within a year of each other so I assumed the tanks would be in similar condition. I did not use the same pumps each time. The comparison period was 4,000 miles on a Ford Taurus. What I noticed was about a 2.5% increase in my mpg over the period. Since then, I've been running Chevron gas.

I'm not sure what else could account for the change, though I know my less-than-laboratory-standards testing could impose other factors. For example, I do know the Taurus uses an electronic distributorless system. Perhaps it's more sensitive? Maybe the pumps at one station are off? Etc. :scratch:

But I'm curious. John, where do you get those stated test intervals? Al, I can well believe different name brands could perform the same. But have you tested major brands vs. no-name generic?

 

[aldive]

I. But have you tested major brands vs. no-name generic?

No, and I shall not ever use them.

Those intervals are educated guesses based on simple math, a few questionable guesses, and baseline figures that I've picked up in conversation with people who (unlike me) do such things as blend or test fuel and other chemicals and also equipment for a living. Basically I'm talking out my arse, but there's a calculator and some good data going into it.

One thing you can be sure of is that in the US, highway gas is pretty well regulated and there is very little difference in the performance of the end product. There are differences in the additives, but it really does take a long time to find cumulative effects between brands or retail suppliers that are even minimally significant in a road driven vehicle.

Gasoline is gasoline for most Americans. Approximately 95% of us get our gas from a common carrier pipeline system. The pipelines function similar to the electric power grid. As soon as the product reaches the pipeline it looses its brand and becomes a gasoline product. All the tank trucks get the same gasoline, no matter what the decal on the side of the truck says.

Gasoline brands are about franchising and marketing not about brand purity.

then why would for the longest time i can remember that ammco gas was the only "white gas" product you could buy while other makers were either reddish or yellowish in color? on a side note i think that todays gas "chevron at least" has got a blue hue to it ....most likelly from the ethanol in it i bet .

Another bit of advice

Just my take.

~Just my 2 cents, but every reliable auto mechanic I've ever talked to has echoed Beauboy's exact same sentiments. I guess it varies in terms of a specific time schedule, but the consensus I've gathered seems to be that a full tank of premium unleaded gas works the best -- maybe once every 3 months (and maybe once a month during the winter months). But even then, most mechanics have told me it's only really a concern at all if your fuel has become dirty or contaminated -- or collected too much water because of non-use of your vehicle. Or, as a simple preventative maintenance measure during the winter months. In my experience, an octane booster has proven to be completely unnecessary. A full take of premium unleaded gas is the real solution -- even if contaminated fuel is causing your vehicle not too start. But, I guess if it's gotten to that point - it certainly wouldn't hurt to throw a cherry on top - and go ahead and pour in that octane booster!
