Lower Octane Fuel
Got a quick question, with Gas Prices on the rise and all, could I put in Regular Unleaded Fuel (87octane), I put the Medium Grade in a few days ago. But lucky for me a friend offered to fill my tank yesterday (did him a favor), so now it's full of Premium, but it's enevidable that i'll have to refill it again. What does everyone suggest??
thanks |

MB recommends 91 octane fuel. AS long as you are within 1 point of that then you should be OK.
Mixing 93 octane with 87 octane will make 90 octane. Some stations only have 2 grades & then mix those to get other octane grades. Ie; Sunoco, also they don't buy crude from the "middle east".

Chris, there's been a lot of discussion about this in the past. Search the archives using the word "octane".
