For the 6 cyl eng what type of gas
Your owners manual will tell you the exact octane rating you need to run. Most of these take regular fuel of at least 87 octane. You can run higher if you want too but you might be just throwing money away. I do recommend that you run top tier fuels to keep the fuel system clean.
If yours is a FFV ( flex fuel vehicle ) you can use E-85. You will have to weigh the pros & cons. E-85 is cheaper but you lose 2 to 3 miles per gallon. E-85 is not as stable as reg. gas. If you don't drive much, I would stick with reg. gas.
