Open Mileage CalculatorJawa 42 E20 FAQ
Is E20 petrol safe for Jawa 42?
Confirmed E20 compatible. The Jawa 42 has been cleared for 20% ethanol petrol since April 2023.
Will my 42 give less mileage on E20?
E20 reduces mileage by roughly 3-5%. The 42's BS6 Phase 2 calibration minimizes this. Higher octane in E20 (RON 95 vs E10's RON 91) helps combustion quality.
Will E20 petrol corrode my 42's parts?
E20 is safe in the 42. The fuel injection system, hoses, and seals are rated for 20% ethanol. Maintain regular oil changes and filter replacements.
