How are Shell Nitrogen Enriched Gasolines different from other gasolines available on the market?
Unlike other gasolines on the market, Shell Nitrogen Enriched Gasolines contain a unique, patented, improved formula exclusive to Shell designed to seek and destroy engine gunk that can be left by lower quality gasolines. All gasoline is not the same—the right gasoline can make a difference in a vehicle. Our research indicates that the minimum level of detergency required by national fuel standards is not enough to keep some vehicle engines free of gunky build-up on intake valves and fuel injectors.
