Diesel, which is typically more fuel efficient, is currently cheaper than premium grade gas, which is a perk for many motorists that drive diesel vehicles. Today, there is a long list of vehicles that require 91-octane or higher. By the way, it’s a myth that premium grade fuel offers any more miles-per-gallon than regular unleaded. Higher octane gas is simply a higher performing fuel that is required for most luxury cars and / or high-performance sports cars. For engines that require higher octane gas, it’s a good idea to follow the recommended octane rating that’s suggested by the manufacture. Otherwise, you could introduce engine knocking to your ride and overtime, it could lead to a damaged engine.
