Premium gas gives you more miles per gallon than regular gas. In actual fact, you’ll get a greater range of fuel economy between different brands of regular gas, than you will between the same manufacturer’s regular and premium gasses.
Is premium fuel really necessary?
Premium gasoline is necessary only for those vehicles whose vehicles say “Premium Fuel Required” behind the fuel door. If your gas brand has higher levels of detergents or cold-weather additives in its premium fuel over regular, it may keep your engine cleaner, but it won’t necessarily run better.
The main difference with premium is its octane rating — 91 or higher compared with 87 for regular octane. The higher octane gives premium gas greater resistance to early fuel ignition, which can result in potential damage, sometimes accompanied by audible engine knocking or pinging. Premium gas is not “stronger” gas.
Is premium gas really better than regular?
Regular gas is rated at 87 octane in most states, while premium gas is often rated higher at 91 or 93. Fuel with a higher octane rating can stand up to higher compression before it detonates. Essentially, the higher the octane rating, the lower the likelihood that detonation happens at the wrong time.
Premium gasoline does not last any longer in storage than regular grade, unless it is alcohol free. In that case it can be stored longer, but it should still be used within a few months if possible. Premium gasoline does not last any longer in storage than regular grade, unless it is alcohol free.
What is the deal with premium gas?
Simply stated, premium gas has a higher octane level than regular gasoline. Gasoline with a higher octane rating is designed to resist engine knock. Your vehicle may also emit lower-level pings when mistimed combustion occurs.
This brings us back to the question of whether you have to use premium gas. In many cases, the answer is probably no — you’ll likely be able to use regular fuel with no noticeable issues except for minor losses in performance and gas mileage. If your owner’s manual says that premium fuel is required, then you should do it,…
Is it good to put premium fuel in your engine?
Therefore, people often think it’ll reduce engine wear. While a tank of premium may help an engine in other ways, using premium fuel once in a while doesn’t really make sense. An engine’s design, which includes such factors as its combustion ratio and its operating temperature, is related to an “octane rating”.
Do you think mileage matters when buying a car?
That’s less likely to happen with a higher-mileage car, unless it has such a golden reputation for reliability (e.g., older Toyota Land Cruisers) that the market considers miles largely irrelevant. The biggest problem with older low-mileage cars is that they haven’t had much exercise.
How can I save money on premium gasoline?
You can try this yourself to see if you can save money by using premium fuel. Monitor your fuel economy and performance over at least two tanks of premium fuel. Record the trip mileage, gallons used, fuel price and octane rating in a notebook or with an app such as Road Trip or Fuelly.
