HELP! WRONG GAS IN CAR
 

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

kill him

you could syphon it out? spell check me on that

Buy some octane booster or buy 91/93 and fill it up .
Or go to the nearest fire station and they will pump it out for you.

Your car just depreicated by 99%. Better sell it to me for $250. Do it fast, because it will start corroding and I won't want it anymore.

any possible damage to engine?

One time wont do it much harm if any really

Besides the chirp, should not do any damage.
Now if it was diesel, whole different story.

You'll be fine.

Just drive it under 3K RPM's with octane booster.

put shit tons of octane booster in it. then slap him and ban him from driving the car. next time he wants to give you gas $$$ say cash only

you should put a sign at your tank saying 91+ ONLY!

Diesel pump shouldn't fit into the receiver on the gas tank.

you would need so much octane booster to make a difference. Just drive it easy until empty.

Mine came with a sticker in the fuel door that says to use premium. I don't know the exact wording but there is a sign that says to use higher octane already.

In modern cars we have octane & knock sensors that can retard the timing in order to compensate for lower octane fuels. You'll lose a little performance but nothing to worry about. Just pump the correct octane next time you pump gas.

That pinging noise you hear is detonation, which is not good for your pistons.

If your tank is half empty, drive gently to the nearest gas station and fill it up with 93. Take it somewhat easy on that next tank until you can fill up with 93 again. Should be fine after that.

Already there

+1. To the OP--Assuming your father is apologetic about this, he owes you a tank of PREMIUM. The car will be fine, one tank of 87 won't make a difference in the long haul. Just drive the car like your grandparents for the remainder of this tank (no heavy acceleration, no revving of the engine, etc.). On the plus side, you may get slightly higher than average gas milage even with the regular gas.

Most likely you have induced irreparable damage to the engine. Consider scrapping the car.


OK, sorry, could not keep a straight face...

Your car is fine. How are you even hearing a knock when the computer has sensors that will detect the first hint and then pull timing out of the curve?

I doubt that even running 87 octane long term would harm the engine; most likely just lose a few of the high load horsepower.

Fill the tank with 91 octane and don't freak out next time. As mentioned the car has a knock sensor that will retard timing when needed.

93+ is the recommended octane rating in the US.
91 can be used when it's not available, without detriment but it's going to lose power and can't be good long term because it's designed to run on 93 octane or higher.

87 would void the warranty and almost certainly cause engine damage.

First part is right, your second statement is completely wrong. There have been numerous users on here who have had 87 in their initial tank from the dealer that have not shown any long-term effect. A single tank of 87 will not void your warranty, nor cause catastrophic engine damage.

Just drive it gently, no throttle blipping or hard acceleration and prevent driving it in hot after noons. It'll be fine.

Geez.... overreaction. Toyota knows that there are some times when you won't be able to get premium gas. Hence, the engine will react to detonation by retarding the spark.

Just think dilution. You have 89-90 in the tank now, since your father filled only half a tank. When it goes down to one quarter tankful, you can boost that to 91 by adding 93. Problem solved. Just go easy on the engine, particularly under load such as going up hills and you won't induce detonation. Relax.

Thanks, Cpt.Leaflet-Reader, but it's clear you haven't a clue how petrole engines work, particularly the electronics that control fuel and spark.

thanks for dropping by.

I bet you triple the US national debt that 99.9% of everyones vehicle here had its first tank of gas with 87 octane.

Dealers NEVER put the correct grade unless you happen to be standing right next to them when they fill it, and even then you might not be able to persuade them.

I was lucky, I had a sales lady that pays attention to the little sticker inside the fuel door. Either that, or she was just covering her ass. I was inclined to believe her. :lol:

Put in 93 and dilute out the lower octane gas. You'll be fine.

I told the sales manager about the fuel requirement and he replied that they put 87 in ALL their cars, regardless of make or model.

I turned around and pointed to the Porsche 911 Turbo and Lexus LFA sitting 30 feet behind me...he replied: "those are the owners cars". I then replied: "and I bet you my new car he put the correct gas in them...".

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.

wrong gas
 

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! :thanks:

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?

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

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.

Chill

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
