Some drivers do not care at all; when they’re running low on gas, they’d simply drive into the nearest gas station and refill their tank. But that’s not how it is supposed to be – some gas stations sell “better” gas than others. How about Shell, do they sell good gas? Is Shell gas good?

Yes, Shell gas is highly rated as a Tier 1 gas, and it’s the favorite gas for most drivers and even automakers. Shell gas is infused with premium additives that are poised to help improve engine performance.

It’s worth noting that Shell gas is slightly more expensive because it is marketed as the “Best” gas for modern vehicles, but it’s expected for a gas of its quality.

This article explains the reason(s) why Shell gas is considered a “better” option than most other gases out there.

Where Does Shell Buy Gas?

In some cities and counties, all gas stations (including Shell) buy gas from the same vendor; however, after the gas is being delivered, the gas stations then add different additives to the purchased gas.

It is these additives that determine if the gas sold in a particular gas station qualifies for the Top Tier category.

Is Shell Gas Good?

Shell gas is a Top Tier gas (also called Tier 1 gas), which makes it one of the best gases to use on your car. But, what does it mean to be a “Top Tier” gas brand?  

For a gas station to be included in the “Top Tier” category, it must be sell gas that meets certain specifications set by a consortium of major automakers globally.

A Top Tier gas is typically free of ferrocene, MMT (Methylcyclopentadienyl Manganese Tricarbonyl, and mixed with a premium additive that meets the industry’s standards for gases in the Tier 1 category. However, companies can add further additives to improve the efficiency of the gas they sell in stations.

The gas sold in Shell gas stations meets the Tier 1 gas specification, which is why many automakers and mechanics suggest you refill at Shell stations.

Typically, Shell gas contains little to zero impurities; this improves the engine’s cleanings, and in turn, improves the engine’s efficiency and performance. In the US, you’d find Shell gas stations in over 14,000 locations. You could even save some bucks on gas refill by signing up for Shell’s reward program.

It is the additives infused into Shell gas that make it a better option over generic, non-tier-1 gas companies. Pretty many people allege that refilling only at Shell helps improve other performance of a vehicle and makes the engine last longer.
