Engines with high compression ratios or turbochargers often require high octane fuel found in premium gas for optimal performance and fuel efficiency. However, the majority of cars on the road today are optimized to run on regular gas.
Can you use regular gas in a turbo engine?
These advances have led some manufacturers to allow fuel as low as 87 octane for their turbo engines – even though the engines usually get more power with high-octane. … If a manufacturer says you can run regular fuel, the engine will be safe, but you might still find gains from running high-octane.
Do all turbo engines require premium gas?
Originally Answered: Does turbo car need premium gas? Not all turbocharged cars need premium fuel, but many do. The reason is that when in boost conditions, the turbocharger increases engine compression to a point where regular 87 octane fuel may pre-ignite and cause pinging and knocking.
Is it OK to put regular gas in a premium car?
Using regular gas in an engine that requires premium could void your warranty. … “Use premium unleaded gasoline with a posted octane rating of 91 or higher. If the octane rating is less than 91, you could damage the engine and may void your vehicle warranty.
Does GM 2.0 Turbo require premium fuel?
For the LTG 2.0L L4 turbo engine, premium unleaded gasoline meeting ASTM specification D4814 with a posted octane rating of 93 is highly recommended for best performance and fuel economy. … Using unleaded gasoline rated below 93 octane, however, will lead to reduced acceleration and fuel economy.
What happens if you put 93 instead of 87?
If you usually fill your tank up with 87-octane gasoline and you accidentally put in a higher octane blend (say, 91, 92, or 93), don’t worry. You’re actually filling your car or truck with a different blend of gas, which means it will burn differently in your engine.
Does premium gas give better mileage?
Premium gives better gas mileage
Because premium gas has a higher octane rating than midgrade or regular gas, it produces a little more power when burnt. Designed for performance cars with large, powerful engines, premium also helps minimize the risk of preignition inside highly-stressed, hot engine cylinders.
How often do Turbos need to be replaced?
Most turbochargers need to be replaced between 100,000 and 150,000 miles. If you are good at maintaining your car and get timely oil changes your turbocharger may last even longer than that.
What happens if you accidentally put regular gas instead of premium?
The ‘science’ behind it. Premium gas has a higher-octane level than regular gas; or, in other words, a higher resistance to detonation. As various pressures rise inside of the cylinder of the engine, this will also result in a temperature rise, and the gasoline will sometimes detonate, or, “explode” in the cylinder.
Do turbo engines require more maintenance?
Do turbocharged engines require more maintenance? The short answer is yes. … A turbocharged engine will not forgive low oil level, poor-quality oil or extended intervals between oil changes. Most turbocharged cars need high-quality synthetic oil and have shorter maintenance intervals.
Does premium gas really make a difference?
Raising the octane rating (also known as the anti-knock index) doesn’t change the energy content of a gallon of gasoline. A higher octane rating indicates greater resistance to knock, the early combustion of the fuel-air mixture that causes cylinder pressure to spike.
What cars take premium gas?

Does premium gas last longer?
Sadly, there’s nothing in premium gasoline that would make it last longer than other fuels from the pump. Since the distinguishing feature is the higher-octane levels, the only real benefit you gain is lowering the chance of engine knocking, which isn’t much of a threat on most modern fuel systems.
How much horsepower does a 2.0 Turbo have?
Two-Stage, Variable-Displacement Oil Pump: the variable-flow oiling system helps maximize fuel efficiency.
GM 2.0 Liter Turbo I4 Ecotec LTG Engine.
|Applications||Horsepower hp (kW)|
|Cadillac ATS:||272 hp (203 kW) @ 5500 rpm SAE Certified|
Is premium gas really worth it?
Typically, high-performance cars require premium, because their engines have higher compression ratios, while other cars can run just fine on lower octane gas. … The FTC sums it up this way: “In most cases, using a higher octane gasoline than your owner’s manual recommends offers absolutely no benefit.”
Why premium gas is a waste of money?
But what is commonly called “premium gasoline” is a waste of money for countless drivers. … A gasoline’s grade is determined by its octane rating, which measures the fuel’s resistance to ignition. Certain types of engines, especially those tuned for higher performance, tend to be higher pressure.
