Alcohol Identified as Silent Killer of Motorcycles

Article excerpt


THE Royal Auto Club of Victoria (RACV) has put together an authoritative report called Modern Fuels and Classic Cars, which has a lot of application to motorcycles both classic and modern, especially in its references to carburetted engines.

The report, applicable to both cars and motorcycles, was prepared in July by RACV research engineer Daniel Wood.

Executive summary

Perhaps the most recent change to modern fuels has been the introduction of bio-fuels.

Bio-fuels have been introduced to decrease our dependence on fossil fuels, clean tailpipe emissions and lower our carbon footprint.

The RACV stresses that ethanol blended fuels should not be used in carburettor equipped vehicles.

A list of vehicles that can use ethanol blended fuels is available at

As a general rule, no vehicle built before 1986 should be run on an ethanol blended fuel, and vehicles built 1986 or after should only do so at the manufacturers' recommendations.

Reasoning for this comes from multiple fronts: materials compatibility, fuel metering, durability and performance.

Questions and answers

Should I run my classic car on an ethanol blended fuel?

No, vehicles built before 1986 are not considered compatible with ethanol blended fuels.

Also, vehicles fitted with a carburettor are not compatible with ethanol blended fuels.

Fuel injected vehicles that have not been indicated as compatible with ethanol blends should also avoid ethanol blends.

What vehicles should run on ethanol blends?

In Australia, two types of ethanol petrol blend's are available, E10 and E85.

Most new vehicles are suitable for operation on E10iv, however, only a select few can run on E85.
