Higher octane gas is usually not necessary for most vehicles and can increase fuel costs. The recommended octane for a car is listed in the owner’s manual or on the manufacturer’s website. Performance vehicles may require higher octane, but listening to the engine can also indicate if it’s needed. In some areas, higher octane gas […]
Octane boosters claim to increase horsepower and efficiency, but testing shows they are not very effective. High compression engines benefit most from higher octane fuels. Using high octane fuel regularly is necessary for good performance, and adding an octane booster well in advance is necessary. Claims about octane boosters can be misleading, and consumers should […]
Octane numbers reflect a fuel’s resistance to engine knock. There are two types of octane measurements: RON and MON. Octane ratings are calibrated against a scale using heptane and isooctane. High-performance fuels have high octane values, and using the wrong octane fuel can damage the engine. It is best to follow the vehicle manufacturer’s recommendations. […]
Octane numbers measure a fuel’s resistance to detonation, with two primary rating systems (RON and MON) and a third average (AKI). Iso-octane is used as a benchmark, and higher compression engines require anti-knock fuel. Octane ratings do not indicate energy capacity, and high octane can refer to high compression, not necessarily more power. An octane […]
Octane gas comes in different grades, with higher numbers indicating slower combustion. Most US gas stations offer ratings from 87 to 92. Octane is a stable fuel used in internal combustion engines. The octane number shows how much fuel can be compressed before ignition. Most cars in the US are designed for 87-octane engines. Higher […]
