Aspen 4 is a premium alkylate petrol designed specifically for 4-stroke engines, such as those found in lawnmowers, rotary cultivators, snow blowers, and boats. Unlike regular petrol, Aspen 4 is ethanol-free, reducing moisture absorption and preventing engine failures. Its clean-burning properties minimize harmful emissions, leading to a healthier working environment and prolonged engine life. Additionally, Aspen 4 can be stored for extended periods without deterioration, ensuring your engine starts easily even after long standstill periods
