I have a Honda Pilot 2007. Does it matter if I use regular (87) or super (93) gasoline?

 

The Pilot is tuned to use 87 octane, so there's no need for anything higher.

 

after a few tank fulls the car can adjust to it but it's not really worth the cost with gas prices like they are.

 

My Odyssey manual says the Van will run on both but will have more HP with the 93 octane. You may have the same setup...so will you get back the extra cost in MPG??? You would have to do a comparison test with a minimum 4 tanks each of the two octanes that you are looking at to make sure that you are not mixing the two getting different readings...I would consider the first two tanks after a switch between tanks a wash since there maybe residual fuel from the previous fill-ups...my father used to mix the two all the time with a fillup of 87 then a half tank of 93 then back and forth...don't think he checked his mileage though but that was his thing...

93 octane has no more power value than 87 octane.
