FAQs about fuel

In addition to being TOP TIER®, Synergy gasoline has 7 key ingredients engineered help provide better fuel economy, lower emissions and improved engine responsiveness**. Plus, Synergy gasolines are designed to provide corrosion protection and improved performance compared with gasolines meeting minimum government detergency standards.

TOP TIER is a standard of gasoline that contains higher levels of detergent additives than current Canadian Government Standards Board (CGSB) standards. The CGSB requires that all gasoline marketed in Canada contain detergents, which are added to gasoline to help clean fuel injectors, intake valves and other engine parts.* The TOP TIER standard is set by a governing body of several automakers and is recommended in their vehicles’ owner manuals. Esso gasoline contains significantly more detergents than the minimum quantity required by the CGSB and has passed other performance tests, such as deposit control on intake valves and fuel injectors, resulting in it being certified TOP TIER. Not only does our gasoline help keep vital engine parts clean, we also remove deposits as you drive.
While diesel and gasoline are both derived from crude oil, they work in two different ways and are not interchangeable. Diesel fuel is designed to operate in a diesel engine, where it is injected into high-temperature air and ignites spontaneously under compression. This differs from gasoline, which is ignited by the spark plugs in a gasoline engine. It is essential that you put the right type of fuel in your vehicle.

In addition to being TOP TIER®, Synergy gasoline has 7 key ingredients engineered help provide better fuel economy, lower emissions and improved engine responsiveness**. Plus, Synergy gasolines are designed to provide corrosion protection and improved performance compared with gasolines meeting minimum government detergency standards.

Generally, regular gasoline will be fine. If the engine is 2-cycle (as commonly found for chain saws or edge trimmers), then 2-cycle oil will be required in the fuel. Consult your owner’s manual for a recommendation.
