What is Premium Gasoline?

Premium gasoline and regular gas both come from crude oil and burn, but the key difference is the octane level. Premium gas typically has an octane rating of 90 or higher. Importantly, this higher octane content in premium gas helps keep the engine clean, reducing environmental pollution.

What is Regular Unleaded Gasoline?

Regular unleaded gas is the most common fuel for most vehicles in Tacoma. It’s a top choice due to its environmental and health benefits compared to lead-containing alternatives. An octane rating of 87 effectively prevents undesired fuel combustion and engine knocking.

The Difference Between Premium and Regular Gas

Premium and regular gas may seem alike, but there are key differences to consider:

  • Octane Rating: Premium gas has higher octane levels, reducing the risk of engine knocking, which is especially beneficial for high-compression ratio engines.
  • Engine Suitability: Regular unleaded gas burns faster and is suitable for engines with lower compression ratios, while high-compression engines benefit more from premium gasoline.
  • Price: Premium gas is pricier, often 20 to 40 cents more per gallon than regular unleaded gas, a crucial factor for budget-conscious drivers in Auburn.

Before deciding between premium or regular gas, keep these tips in mind:

  • If your vehicle doesn’t need premium gas, using it won’t enhance performance or longevity.
  • Using regular gas in vehicles requiring premium usually won’t harm the vehicle, but knocking suggests a switch to premium gasoline.
  • Some turbocharged vehicles perform optimally with premium gas.
