Do Cadillacs Require Premium Gas?

2023 Cadillac Escalade Driving on Highway at Sunset

Do Cadillacs require premium gas or is regular just as good? The answer depends on your particular model. While all Cadillac models can use premium gas without an issue in Graham, some require premium gas to achieve the best possible performance. So if you’d like to know more about your Cadillac CT5 or Cadillac Escalade gas type, keep reading for tips and tricks from our service center!



Premium Gas vs. Regular Gas

Before we dive into the question of “Do Cadillacs take premium gas?”, let’s talk about what premium gas is and how it differs from regular. Regular gasoline is just plain unleaded gas with an octane rating of 87, while premium is formulated slightly differently with an octane rating of 91. The octane rating indicates how well the gas formula resists pre-ignition, or “engine knocks”.

The premium formula has a higher octane level, which means it resists engine knocks better than regular. This is important for luxury vehicles and performance models, particularly models with turbo- or supercharged engines. These engines will usually get a better performance and better efficiency with premium, while regular gas puts them at greater risk of pre-ignition.

Do All Cadillacs Take Premium Gas?

If you’re wondering about your Cadillac XT6 or Cadillac Escalade gas type, you can’t go wrong with premium. Premium will work well in all vehicles, but it’s not required for all Cadillac models. We recommend checking the owner’s manual to double check, but premium is strongly encouraged for the following:

  • Cadillac CT5 
  • Cadillac CT4 
  • Cadillac XT4 
  • Cadillac XT6 
  • All Cadillac Escalade models
  • All Cadillac DTS models 

If you drive a Cadillac XT5 around Weatherford and Abilene, regular gasoline is generally fine to use. But, you can use any type of gasoline without risk of engine damage.
