In Sweden Aspen/stihl alkylate fuel is used in *all* professional small engine work, small lake outboard use and indoor cart racing and so on. Although only 20% more expensive here, it is regarded good business since it reduces maintenance costs even more.
*LIKE* and Recommended.

This stuff is also available from Husqvarna, called Aspen. The preamble of this is "Alkylate Petrol".
In Germany every proffessional forest worker MUST use Alkylate Petrol, it is required.
What is Alkylate petrol?
The name comes from the word alkylation, which is the name of the process used to extract the raw product.
From gas to liquid
The alkylation process takes place at oil refineries through surplus gases from the crude oil distillation and cracking plant being mixed. The result is a alkylateliquid. This liquid is the purest extractable petroleum product.
The alkylate is then mixed with a number of other components and we now have a finished product, ready to be used in most small engines.
Better for your health, the engine and our environment
When you use alkylate petrol, you avoid dangerous substances such as benzene and aromatic hydrocarbons, substances that can cause serious health problems. The engine is also treated more kindly, for example, the spark plug and combustion chamber are kept cleaner. The petrol can be stored and even after long periods of no use, your engine starts without any problem if your tank has been filled with Aspen alkylate petrol. Environmentally, there are numerous benefits, e.g. the formation of ground-level ozone (smog) is reduced by more than 50 %.
Maximum efficiency
Small engines are often uncomplicated and are technically simple engines with less than optimal combustion rates. This means that much of the fuel escapes unused. This, in turn, has a negative impact on both the environment and you, the user.
Better for the user
Aspen alkylate petrol is more or less free from lead, benzene, aromatic hydrocarbons, olifines (“cracked components”) and sulphur. Petrol fumes and emissions from Aspen alkylate petrol are significantly less dangerous to your health than emissions from normal petrol. The air is cleaner and health risks are minimised when Aspen alkylate petrol is used to power your engines.
Better for the environment
Normal petrol is produced through refining crude oil. Different fractions are processed in different ways and are then mixed together. As such, normal petrol contains hundreds of different substances, and many of them have a harmful effect on the environment.
Alkylate petrol is adapted to give the least possible environmental impact. Through only using certain gases from the refinement of crude oil, we produce a very clean petrol that only contains around ten substances. Alkylate petrol is more or less free from dangerous component parts such as benzene, aromatic hydrocarbons, sulphur and cracked components. As a result, AlKylate petrol produces significantly lower air emissions than normal petrol.
alkylate petrol is a ready-mixed (2%) for all 2-stroke small capacity engines with a recommended mix of 2% or 1:50. It is mixed with a synthetic high quality high performance 2-stroke oil for maximum protection and low smoke. This 2-stroke ready-mixed alkylate petrol contains no sulphur, benzene or aromatics. It is therefore much better from a health aspect to use than regular petrol. In fact normal petrol contains so much benzene and aromatics (read solvents) that it is a real health risk to use in 2-stroke engines. Aspen 2T is also chemically inert so you can comfortably leave the fuel in the machine and it will not gum-up. It will also store for years whereas normal petrol start to go off after 30 days.
The ready mixed 2-stroke alkylate petrol also reduces the risk of incorrect mixing eliminating engine failures
And the best thing is, this Stuff is NOT CARCINOGENIC !!
I use ASPEN and i love it.
