Urgent warning tells drivers to avoid little

AN auto mechanic has revealed why you don't want to fill up a particular type of car at any random gas station.

The technician, William, explained in a TikTok that higher horsepower cars, like Kia's Stinger, are more likely to suffer significant engine damage when using specific fuel grades.

The TikTok user's (@concept3performance) video clip starts with him emphasizing how quality over quantity matters when judging gasoline for vehicles.

William noted that the Kia Stinger he's working on in his garage has a dead third cylinder - an engine part that generates power from combusted fuel.

The mechanic said: "The reasoning [for the dead cylinder]: most likely his maintenance wasn't great but also octane.

"Everybody knows gas in California [where William's shop is] sucks, but, in California, your 91 isn't 91, or 89 is not really an 89.

"87 is not even 87. You get it tested, 87 comes out to 85, 89 is about 87, and then 91 is about 89/90 octane."

The numeric octane levels William's referring to represent a gas type's sustainability.

Another name for high-octane gas is premium fuel.

William explained: "But if you actually get it from the 76, that's one of the purest gas stations you can find within the United States."

The mechanic said if you go to Chevron, Shell, or Mobil across the country, the stations often advertise their gas as having Techtron and nitrogen.

William advised viewers with high horsepower cars to avoid using gas with Techron and nitrogen since the ingredients are additives that dilute the fuel and lower its octane level.

The video's technician stated: "On high horsepower cars or turbo vehicles, you need that octane."

Concept 3 Performance clarified in the clip's comments: "If you have a [Toyota] Corolla, [or something similar], fuel that has cleaning additives are good."
