How many points will it raise the octane

Depends on: How big your gas tank is, whether you add it with a full tank, and how many quarts you add.

I have a 2017 corvette supercharged with headers, Will this work with green high flow cats?

Yeah it works with high flow cats. I ran it with a supercharged 17 5.0 mustang making 800whp on stock cats for over two years without issue

Is it oxygen sensor safe

No. This is the leaded formula. Hard on o2 sensors and cats. Get the unleaded version.

What is the smallest engine can u use this on? I got a 1998 3.8l v6 mustang

I don't think engine size is an issue. Does the engine need higher octane? I can't remember if it's compatible with catalytic converters.this product would probably be ok for this motor if it can benefit from higher octane. When we ordered this tho, they sent cetanium instead of octanium (twice). So when you receive it make sure it's octanium and not cetanium , which is for Diesel engines.
