Types of Gas for Nissan Altima
Regular or Premium Gas for the Altima
Choosing the right fuel for your Nissan Altima involves understanding the distinction between regular and premium gas. The key factor is the octane rating, with regular gas typically rated at 87 and premium ranging between 91 and 93.
What is an Octane Rating?
Octane ratings signify a fuel’s resistance to engine knock. Higher octane ratings provide more protection against premature ignition, preventing potential damage to the engine.
So, which type should you choose for your Nissan Altima? The general rule is to follow your vehicle’s manual. Most Altima models can run on regular gas, but some recommend premium for optimal performance. For instance, a 3.5L engine is recommended to use premium gas, while a 2.5L engine operates sufficiently with regular gas.
Using premium gas may boost your vehicle’s horsepower, adhering to the manual’s recommendation. However, if your manual suggests regular gas, the difference in performance between the two is likely minimal.
