Scotty, Love your YouTube channel ! I have a 2020 Acura RDX, 2.0T with 50,000 miles. Reading the owners manual on page 355 under the heading “Fuel Recommendation “ it says “”Unleaded Premium gasoline …91 octane or higher”. In the description it says that use of a lower octane could cause metallic knocking…and will result in decreased engine performance. Use of …octane less than 87 octane can lead to engine damage..” My question is why does autos mfg by Honda use regular gas? Is Acura just trying to “jack-up” their mpg records? I love this car! Jim
Acura is the performance luxury brand of Honda. So the engines in Acura cars are tuned/designed for a little more performance.
Higher octane gas is one of those things that can help get a little more performance out of an engine.
