Fuel ethanol is a high-octane, water free alcohol produced from the fermentation of sugar or converted starch. It is traditionally used as a blending ingredient at low concentrations in petroleum (gasoline) or as a raw material to produce high-octane fuel-ether additives. It is made mainly from grains or other renewable agricultural and agro-forestry feed stocks.
Can I use ethanol-blended petroleum in my Mitsubishi vehicle?
A mixture of 10% ethanol and 90% unleaded petrol can be used in your vehicle, provided the octane rating is at least as high as that recommended for unleaded petrol.
You should be aware, however, that ethanol has a lower energy content than straight petrol and this generally means an increase in fuel consumption.
My Mitsubishi vehicle has a carburettor fuel system. Can I use ethanol-blended petroleum?
If your vehicle has a carburettor fuel system built before 1991, we don't recommend you use ethanol-blended petroleum. Your vehicle may experience hot fuel handling concerns and may experience a lower level of durability in some fuel system components.
Is it necessary to make changes to my Mitsubishi vehicle in order to use ethanol-blended fuels?
Vehicles built since 1986, with the exception of carburettor models, are fully compatible with up to 10% ethanol in the mixture.
If your car was built prior to 1986, or you are unsure of the age of your vehicle, please call our customer help centre before putting any fuel other than that recommended in your Owner's Handbook into your vehicle.
Why is ethanol blended with petroleum?
There are a variety of reasons ethanol is blended with petrol.
Ethanol produced in Australia is not currently subject to fuel excise and therefore ethanol-blended fuel made from Australian ethanol is cheaper. Ethanol is used as an octane enhancer. Fuel octane is described as RON (Research Octane Number). Blended correctly, ethanol can increase the RON of petrol. Nonetheless, use of fuel with RON higher than that recommended by the manufacturer generally does not improve vehicle performance.
Ethanol is a renewable energy source - and as such, helps us achieve the bio-fuel use targets set by the Government in order to reduce our dependence on fossil fuels.
Ethanol production can support and promote local employment opportunities in rural areas where production feed stocks such as sugar cane, wheat, and sorghum are available.
What are the disadvantages to using ethanol blended petroleum in my vehicle?
Poor quality petrol and / or higher ethanol blends can cause problems such as hard starting, stalling, engine noise and hesitation. If you experience these problems, try another brand and/or grade of petrol.
Is ethanol-blended petroleum good for fuel economy?
Ethanol has a lower energy content that petrol, therefore fuel consumption will generally increase when using fuel blended with ethanol. At a 10% ethanol content, it is estimated that fuel consumption will increase in the order of 3%, but actual degradation will be influenced by specific engine technology.
Will ethanol-blended petroleum enhance the performance of my vehicle?
Using an ethanol-blended petroleum will not enhance the performance of your Mitsubishi vehicle.
What is the effect of using ethanol blends on the warranty of my vehicle?
Your Mitsubishi Diamond Advantage warranty approves the use of up to a 10% blend. Anything above that may cause engine and fuel system damage.

Please be aware that the Mitsubishi Diamond Advantage Warranty will not apply in the case of any failure or operational condition attributed to the use of incorrect, contaminated or poor quality fuel in your vehicle. Vehicles with carburettor fuel systems built before 1991 may experience hot fuel handling concerns and may experience a lower level of durability in some fuel system components.
