Does the Type of Gasoline I Put in my Auto Mean Much?

If driving is getting too expensive, consider your ideas about premium vs. regular unleaded gasoline. Most of the time, all you need is standard gasoline, according to the team of auto mechanics at Christian Brothers in Loveland, OH.

There are not any detergent benefits, and expensive gasoline usually doesn’t mean a longer-lasting engine. It’s a false idea furthered by the oil industry. Check the owner’s manual. If premium is ever going to be helpful, it will say so. Don’t give the oil companies more profit!

When engines aren’t created for premium gas, they will not ever have a use for the higher-octane fuel. It is all about combustion. Premium gasoline ignites at a higher temperature, so it can withstand higher compression before reigniting. It also has less heptanes, which also makes it less likely to ignite at low temperatures. Even the government regulators agree – there’s no reason for it in the average tank.

If your owner’s manual does call for premium gasoline, you may not always want it. This is particularly true for anything built since 1996 because your engine will make up the difference. With higher-performance engines that are intended to use premium gasoline, the low-temperature can mean better performance. The premium fuel also prevents knocking or pinging noises. However, unless you’re pushing your engine to the max, the difference in engine performance is minor but the price is much higher. If your engine is knocking with normal use, it’s a different story. For these vehicles, do a little more research or talk to one of our ACE-certified technicians about using the right gasoline.

Is There a Diesel vs. Gasoline Rule?

Gasoline and diesel don’t play nicely together. You could stall the engine and need to be towed. Then, you’ll have to pay the high costs of flushing the system of gas. Diesel is thick and oily compared to gas, and gasoline engines are different in important ways. First, diesel engines don’t have spark plugs. Instead, the fuel is ignited by the heat of compressed air, which is injected directly into the combustion chamber. With gas engines, fuel and air are mixed first and then the spark plugs do their work.
