Gasoline Requirements
Attention:
RedMax-Hi-Performance 2-stroke engine produce higher HP outputs as compared to standard Home
Owner Duty or Light Commercial Duty production engines offered by most manufacturers.
The RedMax Engines are registered and certified with CARB (California Air Resources Board) and EPA
(Environmental Protection Agency) to operate on CLEAN Mid-grade 89 octane or Premium, unleaded
(lead-free) gasoline and RedMax Air-Cooled “Max Life”, Synthetic blend Premium two-stroke engine oil
mixed at 50:1 ratio.
This Hi-Performance Air Cooled 2-stroke Engine requires the use of Minimum 89 Octane (Mid
grade or Premium) clean gasoline. Gasoline may contain maximum of 10% Ethanol (grain alcohol) or up to
15% MTBE (Methyl tertiary-butyl ether). Gasoline containing Methanol (Wood Alcohol) is NOT approved.
Note: IF octane rating of the Mid Grade gasoline in your area is lower than 89 Octane use Premium
Unleaded Gasoline. The majority of all 2-stroke engine manufacturers in the USA and Canada recommend
using gasoline with 89 Octane or higher.
WARNING: Gasoline with a octane rating lower than 89 will greatly increase the engines operating
temperature. Low octane gasoline will cause detonation (knock) resulting in piston seizures and major
internal engine component damage.
NOTE: Failures caused by operating engines on gasoline with octane rating lower than 89 are not covered
by the RedMax Two-Stroke engine warranty.
WARNING: Alternative Fuels (Not Gasoline)
Alternative fuels, such as E-15 (15% ethanol), E-20 (20% ethanol), E-85 (85% ethanol) are NOT
classified as gasoline and are NOT approved for use in RedMax 2-stroke gasoline engines. Use of
alternative fuels will cause major engine performance and durability problems such as: improper
clutch engagements, overheating, vapor lock, power loss, lubrication deficiency, deterioration of
the fuel lines, gaskets and internal carburetor components, etc… Alternative fuels cause high
moisture absorption into the fuel/oil mixture leading to oil and fuel separation.
