Yeah my dealer did the same thing, I ignored their phone calls and their replies. They got their money. My 1st 200+ miles the car was running on regular. Last 2 fill ups were on Premium.

well the day of i filled it up with 91 and added a octane booster drove around for a while and the pinging noise went away and all seems normal lol
thanks all!

dude dealership puts 87 all day.

They can care less.

I didn't say one tank would destroy the engine but it certainly wouldn't be good for it and continued use would almost certainly dramatically reduce the life of the engine.
If you took the car in for an engine warranty claim and they found it filled with 87 octane, even if it was the first tank of 87 octane, do you think they would honour the warranty claim?

thanks for dropping by.

Here's the post.

Hey guys so my dad accidentally put 87 instead of the premium 91 he only put 20$ so about 16L but i noticed a pinging noise more then usual and i asked him and he realized he put the wrong gas in the tanks half empty now but WHAT DO I DO!!!! HELPPPPPPPP

The engine was already knocking with the 91 octane because he noticed 'a pinging noise more than usual', so clearly 91 isn't up to the job for this engine. That's why they say to use 93 or higher.

I run mine on 98RON[US93] and have never heard any pinging[knocking].

He's probably hearing the direct injection knock, it's crazy loud at low RPM under load. I highly doubt the engine can ping itself to the point of damage with the knock sensors, timing adjustment(cam and ignition) and multiple fuel maps.

Other than unlocking a shit storm of sarcasm, you'll be fine.

go away

[#87]

FWIW I know someone who runs a premium required vehicle on only regular 87 gas and they haven't had any problems over 5 years now.

What car was it?
I bet it wasn't producing 100bhp per litre.

It's strange that many people spend a lot of money on this car to increase the performance yet some are defending using cheap fuel as being of no consequence to the performance or longevity of the engine..

I agree half a tank of el cheapo isn't the end of the world as long as it's driven carefully until it's diluted out but long term this car needs 93+ If you can't get that it might not be the right car for you?

At the end of the day its like an extra $4 a fill up. Not a bad investment to keep things in order

I would freak out if I put 91 in my car. 93+ only if available.

But the other are right. I would just fuel it up with octane booster and 91+ you car should be fine

octane rating is relative

here in Ontario, Shell 91 (no ethanol) is arguably better than the only 94 alternative from Petro Can (10% ethanol), and is a reason why people are getting the engine chirp.

therefore 91 is the default gas for us

[firl21]

Octane rating is the resistance to combustion.
The 93 is more resistant to combustion than 89. (this is only relevant in the compression stroke.)
The reason this car is suposed to have 93 is because the engine will run a tad hotter than your average econobox.
Just make sure you dont run the engine hard and keep rpm;s low. The cooler you run the engine the less likely you will cause knock.
