Should the Buick LaCrosse 1.5T use 92 or 95 octane gasoline?
1 Answers
1.5T Buick LaCrosse can use 92 octane gasoline. Here are the specific details about refueling: 1. Although 95 octane gasoline has higher anti-knock performance and power, vehicles with lower octane requirements should not blindly choose higher octane gasoline. Higher octane gasoline is more suitable for engines with larger compression ratios, while engines designed for 92 octane usually have smaller compression ratios. Using 95 octane gasoline may increase engine knocking. 2. Different octane gasolines should not be mixed for use, such as mixing 92 and 95 octane gasoline. Long-term use may have certain effects on the engine, and may even cause engine carbon deposits, increased fuel consumption, and other phenomena.
