running on very high octane (RON > 106) racing fuel. This unleaded fuel replaces to
leaded racing special fuel to keep engine legend, race car or motorbike (4-strokes or 2-
stroke), running with the best quality fuel.
ELF AVSP 11 VS balanced formula makes it easy to use (cold starting, reduction of
vapor-lock and constant injection/carburetor setup). Strong anti-valve recession doping
maintains high protection levels comparable to those of leaded fuels.

motorcycle and car applications usually running on leaded petrol with a very high-Octane
rating.

Ignition timing…).
To replace leaded fuels with octane numbers lowest than 105 (RON) and 98 (AKI), use
on old natural aspired engines, it is recommended to use ELF ATMO VINT.
For 2-stroke use, ELF AVSP 11 VS can be used mixed with ELF HTX 909 lubricant or
ELF HTX 976+.
