WHY SHOULD YOU USE SHELL GASOLINE?
All grades of Shell Gasoline provide unsurpassed protection against gunk. Gunk is another name for carbon deposits that can build up in engines running on lower quality gasolines and act like a sponge in your engine, absorbing and trapping gasoline, and making combustion less efficient. Industry data indicates and car manufacturers recognize that a clean engine is more fuel-efficient, produces fewer emissions and allows vehicles to perform at their best. Shell Gasoline contains a patented cleaning system that actively cleans intake valves and fuel injectors and protects against future build up. No other gasoline protects better against gunk!
