Premium gas doesn’t provide any more power or contain better additives than regular gas, and it contains the same amount of ethanol as other grades. It just resists detonation (knock) better than lower-octane gas—nothing more, nothing less. If so, keep using 89-octane to regain some power and save your engine.
Is ethanol free gas better than regular gas?
While not as popular as the ethanol blends, pure gas may be preferable for older car engines, as well as boats, lawn mowers or other tools. Ethanol-free gas also gets better fuel economy. However, most drivers use the E10 or E15 blends, with 10-15\% ethanol. That ethanol content only reduces gas mileage by around 5\%.
Does 93 octane gas have less ethanol?
Don’t be misled into thinking higher octane gas contains less ethanol. In fact, it has more! The octane rating of pure ethanol is 100, but when it’s blended with gasoline, it performs as if it’s 112. In other words, higher-octane blends — Petro Canada’s 94 and Esso’s 93 — use more ethanol, not less.
Do small engines run better on ethanol free gas?
However, when you’re using gas with ethanol mixture in your outdoor power equipment, like lawn mowers, chainsaws, trimmers and leaf blowers, you run the risk of engine damage and incurring costly repairs. You should be using ethanol free gas in your small engine outdoor power equipment.
Should you put Stabil in non-ethanol gas?
Adding a fuel stabilizer to ethanol-free gas can extend its shelf life and preserve it through the offseason. However, Ethanol-free gas does not attract as much water as ethanol-based gas thanks to the lack of alcohol, so it’s unlikely that you’ll see any benefit unless storing for an extended time.
Does Shell 93 have ethanol?
According to Dan McTeague, a noted petroleum analyst, Shell and Esso 91 are both ethanol free. The octane rating of pure ethanol is 100, but when it’s blended with gasoline, it performs as if it’s 112. In other words, higher-octane blends — Petro Canada’s 94 and Esso’s 93 — use more ethanol, not less.
Is there ethanol in Shell Premium gas?
Shell V-Power Premium gasoline (91 octane) is free of ethanol. Other Shell grades gasoline contain ethanol at the following concentrations: Up to 5\% ethanol in Shell Silver mid-grade gasoline (89 octane), and up to 10\% ethanol in Shell Bronze regular grade gasoline (87 octane). Thank you for choosing Shell.
Does all gasoline contain ethanol?
Almost all gasoline now has some ethanol in it. Our Exxon and Mobil branded gasoline currently contains up to 10\%. Gasoline with 10\% ethanol content is known as E10, and with 15\% ethanol it’s known as E15. Ethanol flex fuel (formerly known as E85) has between 51 and 83\% ethanol with the remainder being gasoline.
What are the benefits of using ethanol free gasoline?
Not using corn to make the ethanol will provide food for more people. It will increase the power of your car. You will get about 10\% more range with a full tank of ethanol free gas.
Why use ethanol free fuel?
Although these blended fuels burn cleaner than pure gasoline, the ethanol absorbs moisture from the air. Over time, that water can separate and drop, along with ethanol, to the bottom of your fuel tank. This is when problems like corrosion, stalling and engine damage start.
