what type of gas do i use for my 2006 mercury mariner hybrid?
I would look into the owner's manual book of the car you have or opening the fuel door (gas tank) and read the words on the inside of the door. It should tell you what type of gas your vehicle takes. I recommend not to take cheap (regular) gas in a hybrid. I believe you would need stronger gas rather than regular.
Regular unleaded. No need or advantage running premium or mid- grade. Doing so will only make your wallet lighter. Just buy "top tier" fuel. http://www.toptiergas.com/ Do some reading at the link I provided.
