So I accidentally put 93 supreme on my 2017 Lexus Nx I always put premium and today I made that mistake will it mess up ?!!

 

Hoping you guys can help ! So I own a Lexus Nx200t and I always put premium gas now today I made the mistake and put 93 supreme I’m panicking, will it do any harm?

 

No harm done.

 

93 is totally fine. Anything less than the recommended 91 octane would be worse. Though even if you had done 89 or 87, modern engines are smart enough to adjust for knocking and pinging. I wouldn't get into a habit of it though as the 200t has turbo and direct injection.

 

You are posting in the wrong section, but the answer is no. Check the manual, if it uses 87, than stick to 87, and if Premium is recommended, than you would use either 91 or 93. If it doesn't take premium, all you are doing is wasting money, but no harm

 

Thank you!!!

 

trust me I know I am but hey I needed to know asap no one was responding on another section I posted but thank you much appreciated!

 

You are good to go!

 

91 and 93 (are) premium fuels.

 

It'll be fine. No worries. Read in your owners manual or on the inside of the gas door and they'll explain things.

 

I am assuming premium is 91 octane. Here in the Northeast, we do not have 91 octane, only have 93 octane so that is all I use.

 

I'm in the northeast here in NJ and we have 91 octane. Usually many Sunoco stations offer it, as well as 93 octane.
My 2020 NX calls for (at least) 91 octane, but I typically use 93 because the 91 is not as readily available.

As long as you use an octane level that's AT LEAST what your vehicle calls for, you'll be okay. In fact, even in an emergency you can use a lower octane, but you'd best fill up with the proper octane ASAP.

 

Welcome aboard.

Both threads have been merged....looks like your question has been answered

 

We have Sunoco 91 here in Boston as well but I only use Shell gas. Years ago, a couple of my Audi had carbon build up in the intake and the mechanic told me to use Shell V-Power gas after the carbon cleaning and I have never had another issue with carbon build up.
