Auto Repair in Mint Hill – How Does Ethanol Affect My Engine?

In recent years the EPA approved the use of E15 to be used in newer vehicles. So many gas stations carry up to 10% ethanol in their tanks these days, gas stations without ethanol advertise it!

The current standard E10 obviously has a lower ethanol content than E15 and there are concerns that the ethanol contained in these blended fuels are damaging car engines, especially on older model vehicles that were not made to accommodate these newer fuels.

What is Ethanol or E10/E15?

E10 is an ethanol blend containing 10% ethanol and E15 contains 15%. As automobile manufacturers are pressured to increase fuel efficiency and cut emissions these fuels are playing are bigger role in helping them meet these standards.

Is it safe to use these fuels?

Newer cars are supposed to be designed for it, however as of 2013, GM and Ford were the only car companies who officially approved it for “new” cars. if you are driving a vehicle made pre early 2000’s is could be a problem.  You can always check the pump where you fill your tank as they are required to post whether or not the fuel you are buying is blended and what content of ethanol may be present in the fuel.  In some areas of the country it is probably impossible to buy gas without some ethanol content and if you do have an older vehicle it most certainly could have an impact on the engine performance and longevity.
