Default Regular Gas Use?
Only able to get 87 in my area for the near-term. I think I know the answer, but I'll still ask: How bad of an idea is it to use the 87 with an octane boost additive?

Don’t do it!

Why do you only have 87 gas? Are you sure there are no options? That’s strange…

He probably lives in Florida. 87 is ok simply don't drive aggressively.

Hurricane Milton. First world problems given what many are struggling with to be sure. For those not in Florida, they prioritize fuel delivery quantities post hurricanes to simplify and speed up deliveries meaning most if not all pumps in a given area will likely be 87 only until supply chains normalizes. I was out of country and couldnt fill up with 93 before the storm. I'll just keep the car up and wait for 93 to return.

Fill up with 87 and buy some octane boost from your local auto parts store. You can then effectively make it 91 or 93 depending on the mixture/ratio. Not the most ideal situation, but can be done.

Octane booster is a great idea and I hope you didn't have any damage with Milton!
Aren't most cars turbo'd these days, requiring at least 89?

Go on Sunoco's website and look to see what local stations carry their 98 & 100 octane. I know it'll be expensive but a lot cheaper than the problems detonation can cause. Also try VP's site.

Octane boost could be more harmful actually. Just put 87 and drive conservative. Let the ECU take care of the adjustment.

You're fine.

The engine will automatically adjust for the octane to prevent knocking.

ECU will adjust. When things settle down, take it in to service and they'll reset ECU and the anti-knock training -- you'll get your power back.

Run 87 and avoid high load situations. Most octane booster in the auto parts stores does essentially nothing...i.e. from 87 to 87.2

I'm in a Hurricane Milton affected area so I filled my 992 with premium pre-storm. My wife doesn't plan ahead so she got 87 octane post-storm for her MB.

Boostane works.

but if you cruise around and stay out of the boost, regular should be fine. Just don’t load the engine up heavy.

I also use Boostane at every fill up. Not sure the long term effects but 91 is the highest in Ak, I’ve read it can make your injectors (I think) turn orange.

What about 3 or 4 gallons per tank of E85?
