Mar 8, 2022 · If your manufacturer recommends 93 octane, that means the car is designed to perform optimally on 93 octane fuel. It may have an iota more power and possibly a hair better gas mileage when you fill it with 93.
Aug 18, 2024 · Increasing pressure in the cylinder allows an engine to extract more mechanical energy from a given air/fuel mixture but requires higher octane fuel to keep the mixture from pre-detonating.
While 95 octane fuel may offer improved performance for high-performance engines, 91 octane fuel provides satisfactory performance for most regular vehicles. Additionally, 91 octane fuel may offer better fuel efficiency and is generally more affordable and widely available.
Apr 29, 2024 · Gasoline with a higher octane rating is more resistant to knocking, providing a smoother and more controlled burn in the engine. Gasoline in Canada typically comes in four main octane ratings: 87 (Regular), 89 (Mid-Grade), 91 (Premium) and 94 (Super Premium).
