Psihawk Posted April 21, 2016 Share Posted April 21, 2016 Does anyone know what octane of gas I should put into my new 2016 Ford Fusion Hybrid? In the past I have always put 89 into my cars (Honda and Mazda). Not sure if that was ever required but just something I did. Wanted to get feedback from everyone here on what their suggestions might be? ThanksSteve 0 Quote Link to comment Share on other sites More sharing options...
dogo88 Posted April 21, 2016 Share Posted April 21, 2016 Should be in the owner's manual. My 2010 takes 89 and i would be surprised if any hybrid took higher rating. Dan 0 Quote Link to comment Share on other sites More sharing options...
Waldo Posted April 21, 2016 Share Posted April 21, 2016 The Atkinson cycle won't really take advantage of anything over 87, so just put in the cheap stuff and enjoy how long it lasts! 0 Quote Link to comment Share on other sites More sharing options...

It is specified in the owners guide. You should read all the manuals twice cover to cover and you will reap great rewards. While parked operate all the controls and display menus. Enjoy. 1 Quote Link to comment Share on other sites More sharing options...
Psihawk Posted April 22, 2016 Author Share Posted April 22, 2016 (edited) As I realize if probably is in the manual as specified above, I was wondering more or less if the higher octane might help. As stated I always have put 89 into my other cars and have good success with them engine wise, longevity, etc. But it seems like everyone here says 87 and no reason to go 89. Just wanted opinions, suggestions and experience, not facts from the manual. Edited April 22, 2016 by Psihawk 0 Quote Link to comment Share on other sites More sharing options...
Waldo Posted April 22, 2016 Share Posted April 22, 2016 If you want opinions, then mine is that you've waster hundreds maybe thousands of dollars in you past cars with the 89. Any modern car will run just fine on 87 unless it specifically says Premium required, in which case you need to go to 91 or higher. 89 is really only useful in older cars that have problems that would cause knocking. 1 Quote Link to comment Share on other sites More sharing options...
FernMTL Posted April 22, 2016 Share Posted April 22, 2016 One of the reasons I would never use 89 gas is that most people use 87 and the turbo engine's owners use 91+, which means you pump old 89 gas in your tank as it is not a popular gas grade. While at it, never gas your car when the delivery truck is fueling the tanks as sediments are moved around the tanks. 0 Quote Link to comment Share on other sites More sharing options...

Most gas stations only have 2 tanks, 89 just takes half from the 87 tank and the other half from the 91 tank. 1 Quote Link to comment Share on other sites More sharing options...
HiGONRG Posted July 20, 2017 Share Posted July 20, 2017 I believe my manual says that a higher grade gas MAY improve MPG. I use 89 and have noticed it provides perhaps 2-4 MPG more than the 87. 0 Quote Link to comment Share on other sites More sharing options...
akirby Posted July 20, 2017 Share Posted July 20, 2017 I believe my manual says that a higher grade gas MAY improve MPG. I use 89 and have noticed it provides perhaps 2-4 MPG more than the 87. No way. The system isn't capable of that kind of improvement just due to octane. Unless there is something wrong with your engine and it's not running properly on 87 to begin with. 0 Quote Link to comment Share on other sites More sharing options...

Not true. It can't happen. Don't waste your money. 0 Quote Link to comment Share on other sites More sharing options...
drolds1 Posted July 21, 2017 Share Posted July 21, 2017 (edited) The manual does not say anything about improved MPG on premium fuel. Besides, 89 octane is not premium fuel It's mid-grade. Premium is 91 octane or higher. This what it says: Premium fuel will provide improved performance and is recommended for severe duty usage such as trailer tow.
