Lower than 91 Octane ok for 03 SE????



I have heard rumors that above 5000ft. MSL it is ok to fill up with Unleaded Plus (middle grade), instead of having to fill up with 91 octane (super unleaded). Is this true? It would be a little bit of help on the dent my wallet experiences when filling up.

Thanks in Advance,



91 Octane

Think of the 91 Octane as a little insurance for you engine. Even though it might cost a little more upfront the higher octane and the cleaning agents Super Unleaded have far surpass its cost. I used to use Regular on my Disco and now I only use 91 because of engine pinging, valve noise and stuff like that. I would suggest if you really have too use lower octane gas but I woundn't make it a habit!!!!!
