It's an Acura TLX with a 3.5 V-6. The owners Manuel recommends High Octane fuel. I am sure it wouldn't hurt the engine if I used a lower Octane in a pinch but on a regular basis it could cause some pre detonation. This car does get pretty good gas mileage it has four driver modes. Econ mode gives the best gas mileage but Sport and Sport+ burns a lot of gas. You barely hit the accelerator from a dead stop and it squeals the tires it's fucking ridiculous, I seldom use sport modes. I've only had this car a year lots of electronic features.

Pre-ignition happens before the plug fires and is a good way to destroy an engine, detonation is usually just annoying.
