The octane rating for E15 (15% ethanol) is 88 octane and E85 (85% ethanol) is 108 octane. In addition, as Argonne National Laboratory states, ethanol reduces greenhouse gas emissions between 34 to 44 percent compared to gasoline.
Which is better 95 or 98 octane?
98 petrol, which is more stable and resistant to ‘knocking’, is a better choice when it comes to engine protection. 95 petrol works as well, but if your engine is powerful, it will use higher pressures that 95 petrol may not be able to withstand.
What is the highest octane fuel?
Premium (the highest octane fuel–generally 91–94)
Why is 88 octane cheaper than 87?
Q: Why is octane 88 priced lower than regular gas? A: Because of government ethanol subsidies, so the more ethanol in the gas, the lower the cost.
What is the Ron of ethanol?
Alcohols tend to increase the research octane number (RON) more than the motor octane number (MON). The blending RON of ethanol is about 120-135, and the blending MON 100-106. The sensitivity (RON-MON) is typically 8-10 units for gasoline, but 14 units for ethanol.
Why is 98 octane better?
Fuels such as 95 or 98 RON (octane rating number) have a higher resistance to burn which indicates higher levels of energy available for the vehicle’s engine. … Using 98 might give 3 per cent reduction over 95, again assuming the computer adjusts the engine parameters.
Can you mix 95 98?
Mixing 95 & 98 is fine, no need to run the tank near empty.
What octane is V-power?
New Shell V-Power unleaded is a 99RON octane fuel. By comparison, regular Shell unleaded is 95RON.
Can you run too high octane?
The higher the octane rating, the slower and colder the fuel burns. If you run too much octane in your engine it won’t run very well because the burn is way too slow. … If the octane is too low, the fuel will burn too fast and too hot which causes detonation and leads to sure-fire engine damage.
Does 93 octane 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.
What vehicles can use 88 octane gas?
General Motors recommends use of Unleaded 88 beginning with its 2012 model year vehicles and Ford recommends Unleaded 88 for its 2013 and newer vehicles. Unleaded 88 is also approved for use by Volkswagen, Audi, Toyota, Land Rover, Porsche, Jaguar, Honda, Subaru, and certain models of Mercedes-Benz and Lexus.
Is 87 or 88 gas better?
The difference is Unleaded 87 has 10% ethanol and Unleaded 88 has 15% ethanol. The 5% increase in ethanol increases the octane rating to 88.
Can you mix 87 88 gas?
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 95 octane have ethanol?
Premium unleaded is both 95 and 98. The ethanol-blended E10 (a mixture of up to 10 per cent ethanol in petrol) is a substitute for 91 in most cars 2005ish or newer. However, it pays to check your user manual. Those numbers – 91, 95 and 98 – are the so-called ‘octane rating’ of the fuel.
What is sp95 E10?
The Unleaded 95-E10 is a new fuel which contains up to 10% of ethanol, in accordance with the latest European specifications.
Which gas has less than 10 ethanol?
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. E15 is only appropriate for use in Flex Fuel vehicles or a very small percentage of the newest vehicles.
