Anyone know where to get higher than 91 octane?

[86main]

I'm just trying to get some high octane fuel to make a video. Tryna see if I can backfire some flames. Lol. Sounds stupid but the video I'm making really needs it..

[86main]

And I actually heard our car doesn't do any good after 93 octane without tune. So I'm hoping this gives me a bit more rich and backfire that out. I have a custom straight pipe done with test pipes and my exhaust always pops like a gunshot at around 3-4k rpm but no flames. Hopefully the higher octane does...

The 92 octane from Shell, Chevron, Costco, and other major (reputable) brands here in WA are just fine in the car, N/A or turbo/hairdryer-charged. The gas at the 7/11 or other quickie marts that offer gas as well tends to be pretty dodgy.

Cenex in some areas offers 92 non-ethanol, the cars are the happiest on that.

91 is junk, usually. That's because in most cases, it's 89 with ethanol added, and from all my testing across 4-5 states, the engine responds like it's 89, ethanol be damned.

Will the car run on 91? Yes, and if it's from a reputable brand, it's generally ok. But it is also likely its going to pull a bit of power on the top end because of the 91, turbocharged or totally stock. Simply moving up to 92 almost always brings it back up to 100%.

The only way you will get flames out of your exhaust would be to dump unburned fuel/air mixture into your exhaust and it ignites on the way out. This is monumentally BAD for your cats and will send them to an early grave. What's worse, is the resulting explosion of the mixture in your cats can damage the honeycomb and cause blockages in your cats resulting in higher backpressure and severe loss of power.


The look that you're going after is caused most often by forced induction blowing extremely hot exhaust through a header, no cats, and a mostly straight pipe. In most movies this is done through post-production trickery.

Sweet, I'll probably go for the 101. Don't know what the difference between leaded and unleaded except the leaded one has lead of course. And I'm pretty sure I'll die from lead poisoning. LOL

Putting race gas in a stock car pretty much just gives you more expensive exhaust fumes.

Well Im making a video for my video class, and few people recommended me I use 100+ octane to see if I can shoot some flames. But other than that, no other reason. haha.

I haven't done too much for my car, I'm waiting for cams to come out to build my internals with cams in. But so far, cold ait intake, semi straight pipe (still got headers)

I'm not gonna drop couple hundred bucks on all these little stuff, saving it for the big bois

Won't happen, even with the exotic fuels. Flames out the rear happen under load, at high rpm, when everything is nice and hot, with no cat's in the system. In other words, while you'll see it at the race track, especially with cars that have been sitting at 5000-7000rpm for the last 30 minutes, you are very unlikely to do it just revving in a driveway.

There used to be a fad of shooting flames out the rear on cars, but they usually resorted to some exotic setups, up to purposely dumping gas into the exhaust and even using a sparkplug at the end of the muffler to provide a spark.

I just filled 92 Octane at the Chevron Extra Mile on 132th Ave in South Everett. I try to only fill there. It was about $3.89 per gallon.

Loan me your straight pipe and I will help you get flames using my car.

Unleaded gets the lead out, as in your car will haul ass. Don't EVER let some clown at the gas station put leaded gas in your tank.

Im 19. haha I also heard, lead isn't actually too bad for your car... it apparently coats your engine with lead and according to O'Rieley, that's a good thing... true? Or bullcrap?
