What is MTBE in race fuel?
Methyl tert-butyl ether (MTBE) is a gasoline additive that replaced tetraethyllead. MTBE is an oxygenate and raises gasoline’s octane number.
Is MTBE used to oxygenate gasoline?
MTBE is produced in very large quantities (over 200,000 barrels per day in the U.S. in 1999) and is almost exclusively used as a fuel additive in motor gasoline. It is one of a group of chemicals commonly known as “oxygenates” because they raise the oxygen content of gasoline.
Is Sunoco race fuel oxygenated?
Sunoco EXO2 is a very highly oxygenated race fuel. EXO2’s high oxygen content – about three times as much as pump gas – can be beneficial in crate engines, two-barrel engines, and racing classes with cylinder head limitations, as well as engines running at higher elevations.
Is oxygenated fuel better?
Oxygenated fuels burn very cleanly than regular gasoline and produce lesser emissions. Alcohol and ether offer the highest combustion efficiency. Alcohol and ethers have higher octane number and oxygen than gasoline.
Does oxygenated fuel burn hotter?
Ethanol may boost a fuel’s octane rating, but results in a fuel with less energy than a pure gasoline, which has a higher calorific content. Oxygenated fuel means burning more fuel to get more power which, in turn, means less mileage from a tank of fuel.
How long will non oxygenated gas last?
As water is the most common cause of fuel spoilage, ethanol-free gas has an extended shelf life of up to 6 months. However, other factors such as a drastic change in temperature and direct sunlight can contribute to reduced shelf life.
Is all gasoline oxygenated?
There are two forms of gasoline as oxygenated form and non-oxygenated form. There are many benefits of the oxygenated form over the non-oxygenated form.
Is Sunoco 110 oxygenated?
Sunoco Standard features a comprehensive additive package to enhance shelf life by improving stability and minimizing oxidation….TECHNICAL DETAILS.

How much more power is gained by using oxygenated racing fuel over non oxygenated racing fuel in a two stroke?
Because it is oxygenated, it delivers up to 7 percent more power than pump gas or non-oxygenated race fuel, but costs more than $30 a gallon. T2 is a non-oxygenated, leaded, 105-octane two-stroke fuel that is already pre-mixed with two-stroke oil at 40:1.
Do you need fuel stabilizer in non oxygenated gas?
Yes, when you’re storing it for a long time. The shelf life of non-ethanol gas isn’t that long. During the offseason, you may want to add a fuel stabilizer to extend its life expectancy. On the other hand, if you’re only storing it for a couple of weeks or months, you don’t need to add a stabilizer.
What is the difference between oxygenated and non oxygenated gasoline?
There are two types as oxygenated form and non-oxygenated form. The difference between oxygenated and non oxygenated gasoline is that the ignition of oxygenated gasoline reduces the carbon monoxide and soot produced during the burning of the fuel whereas non-oxygenated gasoline produces more carbon monoxide and soot.
Why is MTBE banned?
Because of concerns for groundwater contamination and water quality, MTBE is now banned or limited in several states. MTBE is also used in small amounts as a laboratory solvent and for some medical applications.
How can you tell if a gas is non oxygenated?
The key difference between oxygenated and non oxygenated gasoline is that the ignition of oxygenated gasoline reduces the carbon monoxide and soot produced during the burning of the fuel whereas non oxygenated gasoline produces more carbon monoxide and soot. Gasoline is the fuel that we use daily in our vehicles.
What is added to fuel to increase the oxygenated?
Currently ethanol and ETBE are becoming more commonly used as additives to oxygenate gasoline. ETBE is popular because it is typically made from bioethanol, and by some regulations therefore considered a biofuel additive.
What is Sunoco 110 called?
Sunoco® Standard™ is a 110 octane leaded race fuel that is used in many forms of motorsports. Sunoco Standard is designed for compression ratios up to about 13:1 in conventional V8 engines with iron cylinder heads….Specifications.
What are oxygenates (MTBE)?
(A few cities, such as Denver, used oxygenates (MTBE) at higher concentrations during the wintertime in the late 1980’s.) Oxygen helps gasoline burn more completely, reducing harmful tailpipe emissions from motor vehicles. In one respect, the oxygen dilutes or displaces gasoline components such as aromatics (e.g., benzene) and sulfur.
How much MTBE is in gasoline?
Gasoline can contain as much as 10% to 15% MTBE. The main problem with MTBE is that it is thought to be carcinogenic, and it mixes easily with water. If gasoline containing MTBE leaks from an underground tank at a gas station, it can get into groundwater and contaminate wells.
Is MTBE used in RFG areas?
According to EPA’s RFG Survey Data, MTBE has not been used in significant quantities in RFG areas since 2005. A similar decrease in MTBE use has also been observed in conventional gasoline areas. What is MTBE? MTBE (methyl tertiary-butyl ether) is a chemical compound that is manufactured by the chemical reaction of methanol and isobutylene.
What is MTBE and how does it affect groundwater?
If gasoline containing MTBE leaks from an underground tank at a gas station, it can get into groundwater and contaminate wells. Of course, MTBE isn’t the only thing getting into the groundwater when a tank leaks — so is gasoline and a host of other gasoline additives, but in recent years, MTBE has been singled out.
