then again, I've been wrong about tons of stuff before :P |

When I rented a car in North Dakota recently, I had to sign a waiver that if I fueled the vehicle with E85, then I would be responsible for the extensive damage to the engine. Speaking of cats, to answer your question, I'm concerned about emissions and dependence on foreign oil instead of saving the total amount of fluid in the tank. Frankly, I don't look at gas prices - my motivations for saving gas goes farn beyond the almighty dollar. I have to fuel my cars and I pay the price. I usually don't even look at the price or total amount paid unless I print a receipt. I predict people will see huge hit in FE using E85, become frustrated, and go back to gasoline. In addition, the jury is still out on the energy consumed to plant, grow, harvest, process, transport, store, and dispense Ethanol a mostly-new system. From the processing point onward, the traditional gasoline distribution system won't work because of water attraction. I also understand that NOx is increased 3-5% per gallon. If you start to burn this stuff in bulk, expect respiratory problems like asthma to exponentially increase. The EPA is working to remove this and particulate (soot) from Diesel for this reason. Granted, Ethanol does reduce CO2 emissions, but I'm not convinced that it's the best answer to the question. It might be a piece of a varied amounts solutions, who knows. RH77 |

Hi theclencher - ¨I do recall Chris stating that buttery smooth intake tracts are a wonderful thing when in fact state-of-the-art practice holds that some surface roughness in the intake tract promotes better mixture homogeneity.¨
On exhasut ports I polish them to a brilliant shine which reduces carbon build up, which maintains their flow capability for many years. For inlet ports if its a mulitpoint EFI car we polish the ports. This is because the fuel is added just at the back of the inlet valve and doesnt have time to fall out of suspension. On a carby or single port EFI I leave a random paterned surface by using some tough glass paper on a power tool. Any fuel that wishes to stick to the port wall has a hard time due to lack of surface tension.(grip) and it will get reintroduced into the airstream. |

10. That said, I'm not sure E85 is the answer. Quote:

"You will always get better gas mileage with the straight gas vs. gasahol because the alcohol dilutes the BTU's in the gas. And since an automobile engine is a BTU burner you will lose 5-10% in MPG. Try adding K-1 kerosene to your gas or gasahol. I've added 1 gallon per 10 gallons in my gas to offset the alcohol effect, and it cleans your fuel system at the same time. Try it." "Think I stumbled across a combo that might help your winter mileage. 3 ounces of acetone 2 1/2 ounces of Xylene 1 ounce of Ethos FR $15.95 qt ..... $15.95 / 16 = $1.00 per 10 G Ethos FR costs around $.62 per 10 G if bought by the gallon Add this to every ten gallons of gasoline and try it out. You might have to adjust the acetone to what you were getting your best gas mileage with when you were using acetone. In my case three ounces did it for me. Just started using this and mileage went to 21.5 on my F150. The best I could get in winter without anything was 19.0. The best in summer so far with acetone alone was 21. Will keep testing and fine tuning this combo and keep you updated but wanted to share with everyone out there." ""We recently proved that Carb Medic from Gunk (and other GUNK products) can raise mileage when 1 to 3 oz. are used with 2 or 3 oz. of acetone per 10 gallons of gasoline, especially in COLD WEATHER." *LaPointe" "I will say that some have added a few drops of #2 heating oil to about 10 gals of gasoline containing alcohol desiring to 'refresh' the deliberate de-powering of said fuel. Use the heating oil sparingly! Keep in mind that #2 oil is not thesame any longer to diesel. Let us know what you find. LaPointe" "There are of course other additives that improve mileage (which also have had less than a favorable reception by the petroleum industry). Certain octane improvers for example also aid mileage. We recently proved that Carb Medic from Gunk can raise mileage when 3 oz. are used with 2 oz. of acetone per 10 gallons of gasoline, EVEN IN COLD WEATHER. LaPonte" |
K1 and heating oil have sulfur in them and will wreck havoc with the cat and in cold weather+engine will not burn very well producing a lot of white smoke and can cause dieseling (engine run on) after the key is turned off in non-FI cars.
