Does 89 octane gas last longer?
Nada. The octane of the fuel has absolutely no effect on how long your car is going to last. If your car is designed to run on 87 octane then feeding it 89 or higher octane will do one thing: lighten your wallet. There is NO reason to use octane any higher than the engine is designed to run on.
Using regular gas in a car designed for premium will definitely damage the engine. 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.
Does higher octane gas last longer?
93 octane fuels are more refined and contain more stable hydrocarbons. These stable hydrocarbons can last 2-3 times longer than 87 octane fuel. Even in proper storage 87 octane gas can start to degrade in 3 months, 93 octane fuel should last closer to 9 months before degradation is noticeable.
What happens if you put 89 gas in a 93 car?
In most cases, the vehicle will run fine, but you may experience less power and a decrease in gas mileage. In more serious cases, you may hear engine knocking or valve chatter because the fuel isn’t burning right. These things could damage your engine and you should take it to your mechanic.
Why is 89 better than 87?
What is the difference in octane levels? Octane is how much compression a fuel can withstand before igniting, or rather it’s a measurement of a fuel’s ability to avoid knock. Typically “regular” gas is 87 octane, “midgrade” is 89 octane and over 91 octane is “premium” gasoline.
Is 89 gas better for your car?
Most cars on the road recommend a standard grade 87 or 89. Premium gas 90-93 is completely okay to put in a standard vehicle. Car experts say there is no risk of damage to a standard car using premium fuel.
Does 89 gas burn slower than 87?
These octane level numbers (87, 89, 91, etc.) Lower octane gas burns quicker than higher octane, and so require less energy to ignite. However, this also means that lower octanes burn more quickly in high pressure environments, and can have a greater tendency to knock.
Will 89 gas hurt my car?
Is it better to use 87 octane or 89 octane?
However if your car runs on 87 octane without detonation, there is no reason to purchase 89 octane fuel (unless you find it for less money) 87 = regular – 89 = midgrade – 91 = premium in most areas. Most cars run fine on regular, in which case using a higher grade is just a waste of money.
Does high octane fuel really increase gas mileage?
I’ve heard from some people that high octane fuel will increase gas mileage. Around here, we have the basic unleaded(87), mid-grade(89), and premium(93 or 91). I’ve been using the basic 87 unleaded forever because it was the cheapest. Also, in my car’s manual it recommend the lowest grade to use is 87(Grand Am 2004 V6)
What octane gas should I use in my car?
Other engines can simply get by on 85 or 87 octane. Turbocharged engines benefit the most from premium gasoline, with reported gains in both power and economy, and as more cars feature turbos these days, more people will be springing for premium. They’ll have a good reason to do so.
What happens when someone chooses midgrade 89 octane gas?
When someone chooses midgrade 89 octane gas, the pump mixes gas from the two large underground tanks 50/50 to get the 89 octane gas. The Rock reveals the key to success for normal people.
