Most of master in my country didn't allow to use regular (our standard is 92 octane) due to will damage turbo .just wanna clarify is regular ok to use further or use premium for any mechanical damage
Hi ahmedovfirudin. Oooops...I missed the memo that we were playing "Fun with Flags" this morning. And since you did not mention you were not in the US/Canada, I did not notice (and take the time to look up) the Azerbaijani flag in your profile...🤣
To answer your question: Without using too much technical jargon...The US uses a different octane rating system than Europe and elsewhere. The Ford required minimum octane is 87 according to the US octane rating system. And using the Azerbaijani equivalent to 87 octane regular (US octane rating) will not damage the turbos. And that would equate to approximately your 92 octane.
Yes, you can use higher octane (89-91-93 US rating) and get a very slight bump in power (i.e. 10-20hp), but it is not necessary unless you driving your vehicle especially hard and need the power etc.
Short story is: Your 92 octane is the rough equivalent of our 87 octane. So you can take our word for it that your 92 octane is the rough equivalent of our 87 octane, and you do not need to add octane boosters.
Or, if you wish, you can do more research on your own here: https://en.wikipedia.org/wiki/Octane_rating
So it would be a good idea to stop using the octane booster, and se if the CEL (Check Engine Light) goes out after a fuel tank refill or two. However, if it starts to blink, stop driving as soon as safely possible and have your vehicle checked by a good shop/Tech. A blinking CEL is a bad thing.
Let us know how you make out and good luck.
