gasoline and LT1 option
 

Where I am we have 87,89, and 93 octane. What octane for daily use in the v-8 ?
Also, does anyone know if the cold air intake option is offered on the 2020 LT1 package ?
Thanks.

93 always. I can’t imagine GM wouldn’t option the CAI as it’s the same engine as the last 5 years of production.

I only run 93 octane in my car. Lowest you can go is 91 due to the high compression ratio in the LT1 motor.

Performance Air Intake will be available for LT1, 1SS and 2SS but it is late availability. Not available for order yet for 2020 models.

GM recommends 91+, but the car can run on regular.

I run 91/93 in mine, but you can bet that most of the Camaro SS's that you see in rental car fleets run on regular most of the time

Absolutely 93 only. I would drive to another gas station before I put anything less than 91 in my car.

91 minimum. It actually likes more than 91/93.

As a side note I also stick with top tier gasoline brands only. For me these are places like QT, Exxon, Shell, Costco etc. I avoid Racetrac, 7-11 Gas, Wal-Mart/Sam's (Murphy USA) etc.

Runs perf fine on 87, never saw a diff from 91.

It is factory tuned on 93 which is not available everywhere. 91 is good but 87 would be bad. Another reason why this is not my DD.

You’ll see a different in power

93 plus a splash of E85 :thumb:


If you had a tool that could read ECU parameters, you would see quite a bit of timing retard and knock if you used 87. It most CERTAINLY makes a difference, you may just not be able to notice it.

:der: This is crazy talk. :der:

Sorry but do you really think that you know where this gas is actually coming from. Don’t be silly!
