Fuel Requirements Based on Engine Type
However, sometimes people believe that using 91-octane gasoline (also referred to as premium gasoline) is a better way to go in general because it would improve your engine’s performance and lifespan significantly. However, this is not true.
Using premium gasoline won´t hurt your Mitsubishi Eclipse Cross in any way. However, the Eclipse Cross is not designed to derive many benefits from premium gasoline. The only moment it´s necessary for the Eclipse Cross to use 91-octane gasoline is when towing or in very hot weather. This will give the engine a slight performance boost.
What Type of Gasoline Can A Mitsubishi Eclipse Cross Take?
Gasoline/Oxygenated Blends or E-85
We also have to discuss the use of oxygenated blends of gasoline. These types of gasoline contain oxygenates, typically in the form of ethanol or methanol, which are mixed into regular gasoline. These oxygenates are generally made from bio-sources meaning they burn cleaner and are cheaper to make.
However, the use of methanol and ethanol in the Mitsubishi Eclipse Cross is strictly regulated. Methanol is strictly forbidden to use in all generations of the Mitsubishi Eclipse Cross, and doing so will result in corrosion to the engine and fuel system that´s not covered by the warranty.
On the other hand, ethanol is safe to use in all generations of the Mitsubishi Eclipse Cross, up to 10%. For this reason, E10 (10% ethanol) is safe to use. However, E15, E30, E50, and E85 (also referred to as flex-fuel) are not safe to use and will damage the engine.
Addition of Cleaning Agents
If you cannot make use of TOP TIER gasoline and regularly drive short distances, deposits can build up in the engine and fuel system. In this case, Mitsubishi advises you to buy a Mitsubishi Motors Genuine cleaning additive. You can buy these additives at your local Mitsubishi dealer.
What If The Engine Makes A Knocking Noise?
What’s The Gas Mileage Of The Mitsubishi Eclipse Cross?
One area in which the Eclipse Cross does reasonably well is fuel economy. As you can see in the table below, the Eclipse Cross has a relatively small engine in the United States. This results in a decent fuel economy for the size of the SUV.
|Engine||Combined MPG||City MPG||Highway MPG|
|1.5L turbo 2WD||26||25||28|
|1.5L turbo 4WD||25||25||26|
What Is The Tank Size Of A Mitsubishi Eclipse Cross?
The gas tank size of a Mitsubishi Eclipse Cross depends on whether the SUV is all-wheel or front-wheel drive:
- All-wheel drive vehicles: 15.8 gallons (60 L)
- Front-wheel drive vehicles: 16.6 gallons (63 L)
