I have been in a constant debate with a few of my friends as to what is the best gasoline for performance without having to tune the ecu/motor.

I have a TL-S, and my question is could I use jet fuel 103 octane gasoline in my vehicle without having an issue? I do not plan on doing this to my current vehicle, so I would like to see some advice you guys had on the subject.

I am asking since I have a friend, and a few others that tell me this could not be, that actually uses jet fuel in his 2009 toyota camry which is made for 87-91 oct. I have personally seen him pump it into his vehicle and actually have a decent driving difference, was he damaging his vehicle?

The thing which everyone seems to be leaning on is that the tune is American for American gas stations oct ratings, and beyond that it[type S] is designed for 91 only.

You will not run into issues.

I know a lot of people that run 100 octane on their TL without problems.

Is it neccessary? Absolutely not.
You will feel a slight performance gain, but nothing drastic...

Thanks for the input, it only makes sense since you have to use high octane, indeed you are right nothing drastic but they are quite reasonably fast already

I've used airplane fuel before in race cars. There are some caveats about using airplane fuel. I would avoid using JP grade fuels (meant for jet and turbine engines). They are extremely corrosive and will eat through fuel pump impeller blades, fuel lines not rated for JP, as well as the pintle on the injectors. You will eventually start springing leaks with true honest jet fuel (and I have no idea what it will do to emissions system, if you care about that at all).

Cessna grade airplane fuels (designated first with C-rating) can be run without too much worry of degradation of fuel system components. Again, caveats. These fuels are typically leaded which will kill catalytic converters very quickly (if that matters at all to you) and also kills O2 sensors as well. Also if you plan on getting the fuel from your local municipal airport, many of them will not let you pump directly into the fuel tank of your automobile anymore (thanks to people like me ). Also you will probably need to take a sample first to check for water content in the fuel (just like small fixed wing air craft pilots have to).

Some gas stations do have 100 octane race fuel at the pump (not here in CA anymore; big FU to CARB) and you can pump that directly into your system without issue (if you can swing the average $10-$14/gal price).

Hmmm what your saying is quite reasonable, yes I have heard about that not using turbine gas; so I will take your advice.

So what is your opinion on tuning the vehicle to run C-16 race fuel; which I believe is like a 117 octane, plus a lot cheaper from my source than jet fuel. Those are specifically made for vehicle motors, and is that almost the same thing cesna use? I just want to see the difference and my best bet, I am trying to avoid tuning my vehicle and having to add another tank to house the new fuel.

I've used C16 race fuel in the past (thank you VP Racing Fuels!). The only thing is that it is a leaded fuel so it will kill your O2 sensors prematurely. I do wonder what the effects of the lead will do to catalytic converters, but I would suspect an early demise to that as well.

 

[TrustinHFDJ]

Hmmmm ok, any gas/race fuel, with tune that is overall safe for all internals?

And back to not adding mods, any suggestions beyond the cesna fuel?

 

[C25A1guy]

Anything above 100 oct. would probably end up being a waste on factory tune and internals IMO.

Great advice; sealed the deal
