Some EBs, not all of them. For example the ST siblings can run 87, but the Mustang EB needs 91. It's all about the tuning. The STs basically run a detuned map except for when you are at full-throttle, and then you only get the full HP for 15 seconds, which subsequently resets as soon as you lift and reapply throttle.thats unfortunate... Ford says you can run reg in Ecoboost, wonder why?
I assume you are looking at the escape stats. THat's because it runs ~15-16 psi with occasional spikes on a 2.0 engine.thats unfortunate... Ford says you can run reg in Ecoboost, wonder why?
This has to be a typo. All other 1.4 Turbo models (Abarth, 500L, Dart) in the US are "91 recommended" but 87 is okay.According to the User Guide now available for download on Jeep.com, the 1.4L Turbo engine will require 91 octane fuel. The 2.4L will only require 87 octane fuel.
You guys only pay $0.10/gallon more for 91 octane?
Geez you're lucky!!!
Here the 91 costs $0.14/L more... which equates to about $0.53/gallon, or about $6.00 per tank. That would work out to over $600/year for myself. Not a deal-breaker personally (current car is 91 already so I'm used to it) but still... I'm jealous.
You'll really only lose power and MPGs with in very hot weather though. Even if it's like 80 out you'll likely only cause a de-rate if driving it very hard with 87oct.You can run 87 in the 1.4T but you will lose power and MPG's. So the cost difference you save is lost in other ways so it is not worth it to down grade.This engine is on the cautious side when it comes to it's safety so no worries there. Now I have to run 91 because mine is a tad souped up though... :0
This engine is very sensitive to heat. Running with 91, once the outside temp starts hitting 85-90 you can feel the power drop off with normal driving. The harder you drive it, the more it drops off.You'll really only lose power and MPGs with in very hot weather though.

You rarely hit 21. With the 1.4 there is a lot of protection against detonation and damage from heat. In sport mode the most I see is between 12- 16 on the boost gauge. The only time I see 21 is if the outside temps are low enough and there has been a constant airflow through the engine compartment and if I'm in 5th maybe forth gear passing a car. other than that you wont see it.I believe it. 22psi is a lot to run on 91 even.
