Better gas mileage starts with premium gas
Fuel injectors — like spray bottles — don’t work well when they’re clogged. And fuel injectors are an essential part of your car’s engine, delivering fuel at the right time to help support efficient combustion. Some lower-tier fuels can leave deposits on fuel injectors, resulting in decreased performance.
With engine protection built in, Exxon Supreme+ premium gas helps keep your engine cleaner for better performance and gas mileage.‡ How?- Deposits can accumulate on intake valves and fuel injectors
- Exxon Supreme+ premium gas contains detergents that help remove that deposit buildup
- This results in smoother engine operation
- It even helps clean up deposits left by gasoline that meets minimum government standards‡
Premium gas helps reduce friction and protects your engine
Whether it’s dancing shoes or engine parts, friction means wear and tear. When moving parts aren’t protected, friction can contribute to erosion and wear as well as extra strain from heat, potentially reducing engine efficiency and performance. But by fueling up with premium gasoline, you’ll help safeguard your engine from friction.
We added a friction modifier to Exxon Supreme+ premium gas to prevent friction and provide you with our best engine protection ever. Here’s how our modifier helps:- Our friction modifier reduces wear and tear by 30%‡
- This prevents metal surfaces from rubbing together, which can lead to improved performance and better mileage
