May I know what you all use for your UX at gas station? thank you.

 

I use regular, and believe that is recommended. I've had friends who thought they were giving their cars a treat to use premium when not required, but conventional wisdom says this is not true. I'm sure there are people who would argue both sides.

 

87 unless the owner's manual requires or recommends something higher.

So in your case, 87. There are no "sides," there's only facts to this. Anything higher than 87 would not benefit, but actually the opposite.

 

Regular here. Putting anything beyond 87 for something that is NA is a waste of $$$ unless it's directed by the manufacturer.

 

This is why gas is marketed as "supreme" and "regular." It's to trick the small percentage of people into paying more for something they don't need based merely on marketing nomenclature. People figure "Ahh, Supreme!" must be better for my engine.

They don't realize they're actually potentially hurting their engines. Usually not, but in some conditions it could. And certainly it would hurt your wallet. More $/gallon AND lower fuel economy. lose/lose.

I had a friend the other week call me and ask me should she be putting supreme in her Chevy Volt... i'm like uh no. She's like oh well it sounds good. And too late I'm already filling up with it. I wanted to reach out the phone..

 

I just bought a 2024 UX250 Premium. I haven't put gas in it yet, and am trying to find out if it's a good idea or not to use premium gas vs. regular. One dealership told me this car takes regular gas, but another sales guy where I ended up buying it said that it's always recommended to use premium. The owner's manual says not to use anything less than 87 Octane, which is regular. I know that in some cars you really are not supposed to use premium gas.

My previous car was a 2010 Lexus IS250 that did require premium, and that's what I always used. She had 152,000 miles on her before she was totaled when a guy rear-ended me at a red light. She was an amazing car for 14 years, and I'm hoping this new UX will be as well. So I'm trying to get to the bottom of this question: Is Premium gas truly a better option in terms of keeping the car in great condition?

 

Regular.

Anything more than that is laughable for this car.

 

Regular always.

 

I would say go with what the manual states.

That said, i don't know what your petrol is like over there, but here in the UK I tend to use premium. Partly because I get around 3-5mpg more, but also because premium has additional cleaning additives, so it saves on using things like Techron etc.

 

Definitely NOT the cases here in the States.

 

Regular fuel.

Depending on which brand of gas you are filling, will have different additives in the higher octane gas. A lot of them are designed for cleaning the internal components, or for less carbon build up. For example, Shell with their V-Power.

So every once in awhile, it doesn’t hurt to put in a supreme gas fill. Probably old thinking. A lot of these types of additives, though, can be picked up from your local automotive shop.

 

As I have seen in car lists many, many times over the years when this topic comes up, if your manufacturer using recommended regular grade gasoline the only thing it hurts to use premium is your wallet :-)

 

87 Octane . Anything more for a NA engine is snake oil. HOWEVER, brand of gas makes all the difference. Make sure you use a top tier fuel brand. Scientifically proven to clean the engine better with the additives used. Also this is a Port and direct inject engine, so this will make carbon build up a non issue. For me in NY its Sunoco, Mobil , Citgo and Costco. I try to hit Costco whenever possible for the cheapest option

In UK Factory say 95 Octane recommended, means minimum 95 but not limited to. Use 99 will never hurt your engine in model cars, worse case it wont make any positive difference. I've my UX for a while now, I've tested tank to tank E5 vs E10 and I can tell you in UX you wont get any power gain but slightly mpg gain, say around 3 mpg. for example tesco E5 cost 6-7p more than E10, I dont mind pay a few p more for 2-3 mpg gain. But at the end, its your car, if you think you dont need it then you wont need it.

 

Assuming you mean 95 RON which is equal to 91 Octane in the states
