Electronic Fuel Injection (EFI) Frequently Asked Questions.

What is "EFI"?

Electronic fuel injection (EFI) is a high-pressure fuel management system. Just like on today's cars, EFI uses an onboard computer, injector nozzle and multiple sensors to to reliably deliver exactly the right amount of fuel to get the most performance and efficiency out of your engine. Cub EFI is an advanced electronically controlled "closed loop" system that uses real-time feedback to sense usage conditions an instantly optimize combustion to give you smooth running and exceptional starting you can count on, no matter what.

How do EFI engines work?

EFI, or any fuel injection system, utilizes a special high-pressure fuel deliver nozzle to inject an ultra-fine mist of fuel into the engine. An electronic control unit uses sensors around the engine to deliver the precise amount of fuel the engine needs, improving response, efficiency and starting. Cub EFI adjusts the fuel metering on-the-fly to compensate for variations in load, speed, fuel, temp and pressure to always feed your engine the perfect charge that it needs for maximum performance at any task.

Do EFI engines require less maintenance?

Yes. EFI systems produce cleaner combustion, resulting in a cleaner engine Clean engines can go longer between regular oil changes and required major maintenance. We do still recommend a fuel stabilizer for long-term storage to make sure the fuel in the tank stays fresh so you'll be ready to mow with a push of a button next spring.

Are EFI engines more resistant to fuel system corrosion and "ethanol damage" so often seen today?

Yes. The fuel system is ethanol-resistant and compatible with gasoline fuels up to E20 (20% ethanol) blends. Unlike carburetors, the EFI system doesn't rely on mechanical components and easy -to-clog jets. Critical EFI components are totally sealed, making the entire system more tolerant to today's common automotive gasoline blends.

Does the Cub Cadet EFI engine accept E85?

No. E85 is a blend of gasoline containing mostly ethanol (85% ethanol and 15% gasoline). Today, Cub EFI engines only accept up to E20 (20% ethanol) blends.

Does Cub Cadet EFI engines accept diesel fuel?

No, it only accepts gasoline with blends of ethanol up to 20%. Protect Your Purchase ×
