I put wrong fuel in 86 gts
 

Hey guys, I own an 86 gts, 2 yrs old now.

I live in Sydney Australia. Today I accidentally filled the car with roughly 5 litres of 94 ethanol e10. I quickly realised and stopped, and filled up the car with 98 octane. My question is... do I need to get the petrol drained from the car?

The car was empty when I first started filling up.

I am concerned with the injectors :(

you should be okay since it was a small amount, just keep trying to dilute the gas with higher octane

Thanks for letting me know. I have 90km trip tomorrow, and once done I will fill up the car again with 98 to dilute it. I tried checking online but it only says up to 2017 model is compatible.

100% ok. If you check your manual you will see that 98 is recommended but 94 is required. You can even use 91 now and then with no ill effects other than a drop in performance.

Probably should try to avoid driving it hard until you use up all the fuel or have mixed in enough premium in to actually have a 98 in the tank just to be safe. I'm sure the computer is compensating for the lower octane, but it doesn't hurt to play it safe.

Read my post above. It is the same as us using 91 octane and will not harm the car in any way.

Doesn't it say that using lower grade fuels can cause knocking?

The manual says minimum 91. His 94 is our 91. It is a total non issue. Even the drop in performance is almost non existent for street driving.
We can run 89 for brief periods without harm as well but I wouldn’t use it all the time and the drop in performance is noticeable.
There are many people that can’t even get anything more than 91.

Welcome to our forum, there, Jp8802 - :clap:

Your car will be OK, not to worry.

:slap: Just pay attention next time - ;)

:slap: Kaotic Lazagna, you have been around long enough to know about that. Damn, iffen your short term memory is that bad - refresh it - look it up.

Oh, wait - maybe you are just trolling ol @Tcoat - :iono:

I assumed their 94 was our 87. I'm sure that what ever he got is better than the 91 we get in California :sigh:

Wait, what am I missing. I wasn't trolling this time.

I would be worried if you poured diesel into the tank.. Petrol grades can be variable so no great shakes if you go up or down on octane levels..

As has been already said, you'll be fine- ECUs are wildly intelligent.
You wouldn't believe the variances in the fuel you're getting, but you don't need to worry about it; the ECU has your back. As long as it's not diesel or water..
