My manual 1LT V6 with a borla x pipe connected to the stock system just ran a 13.5 1/4 mile on the factory 18 inch M&S rated tire and no other mods. I was able to pull a 2.0 60ft time also indicating a good launch. This car runs on nothing but 93 octane.

Other thread on this:
https://www.camaro6.com/forums/showthread.php?t=440726 In it, someone claims that on the last generation V6, LFX, somebody checked and the engine was in fact pulling timing on 87 octane. When they changed to 91 (or 93)? that went away. It didn't result in any significant dyno gains but subjectively people felt that the power delivery was smoother. Whether that translates into any real world benefit, I don't know. But it kind of sucks to put 87 in your V6 knowing that it is pulling timing. I'm not sure if thats proven with the LGX but its a good bet that's the case. |

The v6 is direct injection it is rated at 87. See below for how it does it.
Direct Injection (DI) As the name suggests, DI involves injecting fuel directly into the cylinder. While this system does provide greater control of the combustion cycle, that is not the greatest benefit of DI. Because it is sprayed directly into the cylinder, and not warmed first in the manifold on the other side of the intake valve, gasoline entering the cylinder actually cools the combustion chamber. This cooling effect reduces the chances of fuel “pre-ignition,” which has two significant benefits. First, DI improves engine efficiency by allowing the use of higher compression ratios. Simply, the mixture of air and fuel can be squeezed more tightly by the piston before it is ignited—this allows for a more complete fuel burn and thus better energy utilization. Second, the need for more-expensive, higher-octane fuel is reduced. A fuel’s octane level determines its resistance to pre-ignition. As DI reduces the occurrence of pre-ignition, it enables an engine that might otherwise need premium fuel to run on mid-grade or regular-grade gas. |

Running on 87 octane
Chevrolet claims of 0 to 60 at 5.1 is pretty much on target. I have tried numerous times on 87 octane in my 2019 camaro rs v6 but my problem is the lack of rear traction and the car pulls very hard. My best time to date is 5.2 but this camaro fills like it can hit or break the 5 second mark. Unfortunately I didn't record the 5.2 but I did with the last run which was 5.3.

So - I just ordered a V6 and while its going to be a while until I get it, was curious if there is any benefit to running ethanol-free fuel which around here is 90 octane? Or is the 93 with octane the way to go?

By running premium all the time (especially during the warm months) the V6 tune will always be in the max timing tables for max power and efficiency. Run 87 octane during the cold months when your not looking for max power.

Just to clarify the LGX in the Camaro is actually 11.5:1. Although I've never seen a difference in 0-60 times (87 vs 93) I'd be curious if there's a difference in say really hot summer temps and/or several back to back runs where an engine could see some definite heat soak

I think if I own a V6, I would just be using regular unless I am hitting the track, then I will bump up to premium for some safety margin.
The easiest thing to do is just to get a Bluetooth OBD2 capable of reading live data and then read the knock retard. That will answer all your questions. Maybe your local gas is crappy enough to warrant mid-grade, maybe not. And 11.5:1 isn't that high of a compression nowadays. Mazda Skyactiv engines have 13.0:1 compression ratio and run on regular gas just fine. Granted, they have a few tricks to make it work and their engines are more geared towards economy nowadays, but IMO the octane maps will play a bigger role than compression will on an NA engine. The other thing is, I have two accounts locally that tell me that their V6 burns about the same amount of gas as my V8 in stop-and-go traffic, so their only saving grace is that they need regular. If their gas mileage is that bad in the city and you are feeding it premium... Why did you buy a V6 again?
