bbf2530 Posted January 23, 2012 Share Posted January 23, 2012 (edited) hi guys i used octane 87in my 2010 fusion 2.5L over a year somebody told me i should use 91 octane i think that waste my many is there a different between 87 and 91 octane Hi fusion2010. :D This is an often asked question. The short answer? If you check your Owners Manual, you will find that the recommended fuel for your car is 87 octane and that Ford specifically advises against using higher octanes/premium fuels (assuming there are no special requirements for Dubai). The ECM/PCM/engine management system of our cars is not programmed from the factory to take advantage of higher octane fuels, therefore using them can cause engine issues. Bottom line is it comes down to who you want to trust: the people who designed engineered and manufactured it (Ford), or someone else who thinks they know more than Ford. Seems like an obvious choice. Whatever you decide to do, good luck. :beerchug: Edited January 23, 2012 by bbf2530 0 Quote Link to comment Share on other sites More sharing options...
Goneracin Posted January 23, 2012 Share Posted January 23, 2012 well yes there is a difference in the actual fuel, however if your engine does not have high enough compression to require the higher octane, then i dont see the point. there is an old belief to put in 93 octane once in a while to clean out the engine. higher octane might burn a little hotter (i really dont know, so someone please correct me if im wrong) but i dont think its enough to make a difference. you are better off staying with the factory recomended octane, and just using quality fuels, try to stay away from discont brands. its not worth the $0.15 savings. thats just my 2 cents. hope it helps. 0 Quote Link to comment Share on other sites More sharing options...

The reason people believe that Premium cleans out the engine is that in the past they only put detergents in Premium. So while that used to be true decades ago it's not true today. 0 Quote Link to comment Share on other sites More sharing options...
FusionDiffusion Posted January 23, 2012 Share Posted January 23, 2012 Unless your 91 octane is ethanol-free, there's no good reason to use it over 87 octane. Use 87 octane if you are budget-minded. The reason people believe that Premium cleans out the engine is that in the past they only put detergents in Premium. So while that used to be true decades ago it's not true today. I believe this still the case in some instances. Shell's V-Power premium has more PEA additive than the other grades I believe. But all gas sold today should have more then the federal required amount of detergents, so you should be fine with 87. You can just use a bottle of Techron every 5000 miles and get the same benefits for less. 0 Quote Link to comment Share on other sites More sharing options...
Goneracin Posted January 23, 2012 Share Posted January 23, 2012 thanks for the info akirby, that makes sense. i know that when my mustang was 11.7 to 1 compression, the car ran a heck of a lot better on 100 octane than it did on 93. but then again, our fusions arent anywhere near that compression level. if money was no object i would run that 100 octane turbo blue all day every day. just something about the smell on a non catalyst car 0 Quote Link to comment Share on other sites More sharing options...
fusion2010 se Posted January 23, 2012 Author Share Posted January 23, 2012 thank for you all I'll keep use 87 0 Quote Link to comment Share on other sites More sharing options...
mtburg43 Posted February 13, 2012 Share Posted February 13, 2012 Go to fleet-farm and run mid grade-ethanol-free/ Worth the extra money and works great! I have 2011 SE I4 with BP 10% ethanol i AVG 27 MPG with Fleet farms mid grade and no ethanol i AVG 29 MPG. The only thing ethanol is good for is saving the oil company money and to bring you back faster to fill up your car. Ethanol is like dumping water into your gas tank. I hate ethanol its EVIL! 1 Quote Link to comment Share on other sites More sharing options...
drolds1 Posted February 13, 2012 Share Posted February 13, 2012 Go to fleet-farm and run mid grade-ethanol-free/ Worth the extra money and works great!

The only thing ethanol is good for is saving the oil company money and to bring you back faster to fill up your car. Ethanol is like dumping water into your gas tank. I hate ethanol its EVIL! Your thinking's a little off here. Not everyone has the choice to buy 100% gasoline. There are 46 other states in the U.S. that don't have Fleet Farm gas stations. Some states mandate E10 fuel. So how is it a conspiracy on the part of oil companies? It was the U.S congress that passed the Clean Air Act, part of which requires that certain areas use reformulated gasoline. EPA website: The Clean Air Act requires certain metropolitan areas with the worst ground-level ozone pollution to use gasoline that has been reformulated to reduce air pollution. Other areas, including the District of Columbia and 17 states, with ground-level ozone levels exceeding the public health standards, have voluntarily chosen to use reformulated gasoline. Reformulated gasoline reduces emissions of toxic air pollutants, such as benzene, as well as pollutants that contribute to smog. If [use of] ethanol is like dumping water into your gas tank, try diluting your gasoline with 10% water and see how your car runs. 0 Quote Link to comment Share on other sites More sharing options...
Waldo Posted February 13, 2012 Share Posted February 13, 2012 I'm pretty sure the OP isn't going to find any ethanol in the fuel in Dubai. Then tend to have a lot of oil over there and not a lot of corn. 0 Quote Link to comment Share on other sites More sharing options...
mtburg43 Posted February 13, 2012 Share Posted February 13, 2012 (edited) Here’s the top 3 disadvantages for ethanol fuels: Ethanol fuel absorbs water – it actually combines with water. Ethanol is a drying agent and can dissolve rubber, plastic parts, etc. Ethanol has a shelf life of 60 to 90 days under ideal storage conditions. When gasoline absorbs water it is contaminated and must be discarded. So what damage can it cause in to your engine? Ethanol can dissolve resins that create a black sludge that coats the inside of the engine, clogs fuel filters, carburetors and fuel injectors. Ethanol can dissolve and destroy non alcohol resistant parts Ethanol makes a great cleanser. You may say that’s good for cleaning the inside of your engine but all the contaminants circulate throughout the engine and clog and damage engine components. Ethanol ignites at a higher temperature. This can cause damage to pistons. Ethanol over 10% will damage most conventional engines. THIS IS WHY GOV WONT ALLOW THEM TO USE 15%..! My thinking is right on! I do know every state does not have fleet farm. But just saying! Edited February 13, 2012 by mtburg43 0 Quote Link to comment Share on other sites More sharing options...
Blue 11 Fusion Posted February 18, 2012 Share Posted February 18, 2012 Except all cars built after 96 I believe have to be able to use E10 fuel. Which means the entire fuel system needs to be able to tolerate at least that much Ethanol in the fuel. 0 Quote Link to comment Share on other sites More sharing options...
