Jun 20, 2014 · In the Key Product Specifications (page 57) it says fuel requirements 87(min)/91+(rec). If my focus for purchasing the mustang is styling and fuel economy with the Ecoboost engine and not so much performance, I wonder what would be most effective. Ford, please don't give me choices - just tell...

Jul 15, 2024 · The take is they are wasting money buying the higher octane fuel. The engine cannot take advantage of the extra octane ceiling. A gallon of 87 octane fuel has the same energy density as a gallon of 91 octane. The higher octane allows the timing and/or compression to be altered to eek out a bit more power before preignition (detonation/knock ...

Feb 1, 2019 · Since the amount of ethanol is relatively low I would think the air/fuel system and stock tune should be able to handle it and take advantage of the higher octane. So what do you guys think? Anyone see any flaws, issues, concerns with running E30 fuel? Anyone run a similar type of blend fuel using ethanol on the stock tune?

May 29, 2020 · 91 octane is the best I can get around here but pure gas is available at a premium price. Which is better for a boosted application?

Jun 20, 2014 · But 91 is the minimum required octane requirement for the GTI. The new Ecoboost is 87, with 91 or more being "recommended." The Ecoboost will run much better than our GTis on 87 octane, but it'll pull stronger and get better fuel economy with premium. The only fuel I'd run in the Ecoboost would be Shell V-Power (93 octane with lots of detergent).

Jul 15, 2024 · Diesel fuel must be of a higher-octane rating than gasoline since it requires more compression to self-ignite. But when it does ignite the fact it was compressed much more gets more efficiency out of the fuel.

Jan 21, 2024 · E85 requires 30% more fuel than your regular pump gas which means a return style fuel system. For 91 Octane fuel, 580whp is about average. Those Ev6's are just about tapped out.

Jul 15, 2024 · Hello; Again in the Engine Masters episode they stated the engine was optimized for 91 octane. Their concern was the portion of running 87 octane which was why the dyno operator pulled 5 degrees of timing before starting the 87 runs. He then added timing gradually. He also adjusted the air fuel mix in a similar way. This optimization of the timing & air fuel was also done for the other higher ...

Jun 12, 2017 · After the Mustang Memories meet in August, I'm going to return to Wisconsin up through Canada via the Lake Superior Great Circle route. How available will high octane fuel be?

May 6, 2015 · hi have a manual eco boost 2015 mustang. live in west texas near the border and only see 91 octane premium fuel. was wondering have much power and torque I lose will running 91
