Less ping better performance
Well its not cheep. But it really does what I need it to do. I have a 67 built triymp spitfire that can run on 101 but can only get pump gas. It keeps the pre igniton to a min . I use one can for 10 gall. The funnel is worth keeping for other additives

I discarded the entire order

Clogged the Catalytic Converter on my 2020 BMW within 9 months
It might be okay to use once or twice but using this consistently as a way to increase fuel octane will clog your cat. It has MMT. I had to have my catalytic converter replaced because of it. Read your car manual, see what it says about fuel. Will not buy again, I might just buy actual high octane race fuel now and mix it with normal gas.

Works as descu
Product put in 1966 corvette engine which requires higher octane than available now, improved performance and engine runs smoothly, like it did new in 1966
