Fuel
Ethanol - What type of fuel in vehicels with ethanol?
Vehicles intended for E85 or an optional mix of E85/petrol, such as Flexifuel, Biofuel, etc, and vehicles converted by BSR with Certified kit E85c or BSR E85-tuning are most suited for use with E85.
Using E85 the vehicle will consume more fuel, depending on temperature, number of starts and driving method.
In general to the fuel cost will be lower with E85, but this depends on the price difference between E85 and petrol. E85 is always environment friendly and can give increased engine power, since E85 has a higher octane rating (104) than petrol, which the engine can utilize to maximize the power.

Ethanol Consumption - Will ethanol increase fuel consumption?
Ethanol has lower energy content than petrol, E85 is approximately 40 % less than petrol and therefore more fuel is consumed to achieve the same effect. By optimizing and utilizing the positive qualities of ethanol - for example, E85 is 104 octane - the efficiency can be increased and the higher fuel consumption can be reduced.
Normally consumption is measured during exhaust certification tests. But these usually display slightly lower values than normal driving.
BSR has performed tests on our E85 tuned cars, see http://sv.bsr.se/news/170/. These fuel consumption figures cannot be guaranteed since the consumption depends on a number of factors, where driving style is very important.
A Swedish motor magazine, ”Bilsport” performed a series of test on 3 different flexi fuel vehicles (Original FFV, not converted). No 14/15 3-7-30/7 2008¨.
Both ”tests” show that the additional consumption during longer distances is “good”, especially during high temperatures. (Bilsport).
The consumption increases especially during winter, at cold starts and during shorter distances. The amount depends on temperature, the distances and driving manner.
It is also worth considering that during the winter the E85 fuel contains more petrol, approximately 25-30 %, instead of the usual 15 %, and this can affect consumption marginally.

Fuel consumption – Tuning and fuel consumption?
Will the car use more fuel during acceleration and increased load?
The general principle is basically: the more power the more fuel/air blend. The fuel consumption can increase during acceleration due to the amount of power required.
The total consumption always depends on driving methods, maintenance etc. By exclusively using the extra power when it is really necessary and by a form of instinctive “eco driving”, you can achieve good fuel economy even on BSR’s tuned engines.
These elements mean that a car tuned by BSR in general has lower average fuel consumption then before the tuning. BSR and our clients experience that the fuel reduction is 3-5%.
We have not documented the fuel consumption during tuning. This would require sophisticated test procedures with completely identical driving schedules under identical conditions.
BSR does not guarantee any fuel reduction.
By installing sport air filters and full flow exhaust systems less resistance is achieved and this can give a fuel consumption reduction.

Consumption - Promises of reduced fuel consumption!
Some tuning product suppliers market their products with a promise of pronounced reduced fuel consumption, sometimes called "eco tuning”.
Hidden behind these wordy promises and sales friendly statements is often a threat to the environment which has the opposite effect on the environment as well as on durability.
Car manufacturers spend a lot of money on fuel saving development since this is a very important part of their marketing. They are also hard pressed to meet exhaust emission control requirements.
An engine requires a certain amount of fuel for cooling. Technically, it is not hard to reduce the fuel amount of a fuel map without reducing the engine's performance. The consequence of this is that the exhaust emission temperature will increase and this will give a marked increase in nitric oxides (NOx, please see FAQ Exhaust Emissions). The risk of engine damage, especially during high loads, will also increase considerably.
DEKRA, an accredited testing institute in Germany, has performed tests on products promising lower fuel consumption (some in combination with promises of increased power). Tests were carried out on everything from bogus products to optimization systems from serious suppliers.
The results were not unexpected; none of the products promising lower fuel consumption could hold their promises.
See the story (in German only): http://www.zdf.de/ZDFmediathek/content/475544?inPopup=true
Sometimes the technical knowledge of the tuning suppliers does not always match their promises.
Environment responsibility is very important and awareness can be reached if customers and authorities demand that the suppliers have the required qualifications and competence.

Will my car run on E10 fuel.
The majority of cars on the roads today will be able to switch to the new petrol quality without any problems. For example, all BMW cars regardless of model year can run on E10, all Saab models from model year 1979, and all Volvo models from model year 1976 except Volvo S40/V40 with Mitsubishi's GDI engine of 1.8 liters produced from the mid-1990s until the summer of 2003. Cars who can not run on E10 fuel is referred to the 98-octane petrol which will remain in place (how long is however unclear). 98-octane gasoline will continue to contain five per cent ethanol.
If you want to know if your car can handle E10 or not, we refer you to your car manufacturer.

Quality - What type of fuel should I use when tuning?
Petrol cars
To get the power declared by BSR when tuning, use 98 Octane (EU)! If you use 95 Octane (EU) you will not get the full effect increase stated for our tunings.
Using 98 Octane (EU) will also reduce the risk of detonations (uncontrolled ignition).
Note: When we say 98 Octane (EU) we obviously mean unleaded!

Octane rating – Information about octane/cetane ratings
The octane rating of gasoline tells you how much the fuel can be compressed before it spontaneously ignites and causes engine detonation. The higher octane rating the less the risk is for knocking.
There are two ways of measuring octane rating: RON and MON:
RON= Research Octane Number
MON= Motor Octane Number
The MON number is lower than RON.
There a three ways to present octane rating:
1) RON (EU)
2) MON
3) RON+MON/2 (USA)
In the US they use the formula (RON+MON)/2 which gives a mean value of (98+88)/2=93 octane
- Low octane fuel can damage the engine, it increases the combustion and causes damages to the environment.
- High octane fuel increases the life of the engine, reduces fuel consumption and reduces environmental stress.
More information at: http://en.wikipedia.org/wiki/Octane_Rating
Cetane rating is a measure of the combustion quality of diesel fuels. A diesel fuel with a high cetane number has a high tendency to autoignite.
