The Importance of Additives In Enhancing Engine Performance

Additives play a crucial role in gasoline, including ARCO gas, as they contribute to engine performance and longevity.

Detergents and cleaning agents in gasoline help prevent and reduce engine deposits, ensuring optimal combustion and reducing emissions.

While ARCO gas meets the minimum requirements for additives, other brands offering Top Tier gasoline may provide a higher concentration of these beneficial substances.

By incorporating a higher level of detergents and cleaning agents, gasoline can effectively clean fuel injectors, valves, and combustion chambers, leading to improved engine efficiency and reduced maintenance needs over time.

Arco Gas Vs. Other Brands

Arco and Top Tier Gas

Arco gas is known for its lower prices compared to other national brands like 76, Shell, Chevron, and Mobil. While Arco is owned by BP, they do not necessarily offer Top Tier gas.

This is a classification of gasoline endorsed by major automakers, including Marathon Petroleum, Amoco, Tesoro Petroleum, and Texaco.

Top Tier gas contains a higher concentration of detergent additives that provide better engine performance and reduced carbon deposits.

According to a study, non-Top Tier gasoline can have 19 times more carbon deposits than Top Tier gasoline.

The company keeps its prices lower by not accepting credit cards and implementing efficient cost-cutting measures.

Other brands like Costco also offer low-priced gasoline without compromising on quality.
