Sunoco racing methanol is produced to the highest possible standards. Its purity normally exceeds 99.85%. Methanol’s high octane value and oxygen content (50%) make it a popular fuel. Along with the ability to produce good power, its combustion is colder than that of normal petrol, helping to control engine temperatures. It does, however, have drawbacks. It is very corrosive when in contact with soft metals and certain types of rubber materials.
From a safety perspective, it is important to be aware that it burns with a colourless flame. We recommend adding Alky, which increases the lubricity of the methanol and also makes it burn with a yellow flame. If you are using methanol as a fuel in any MSA-sanctioned racing event, you are required to use Alky, or a similar type of product, to increase the level of safety for yourself, spectators and circuit staff.
