4oz to a full take of 93 pump gas, they actually sell 4oz shot bottles but they are way overpriced but I bought them anyway and will refill them since they are super convenient.
Why do you prefer E85? I had huge problems with it. My car didn't like it at all. 5gal of E85 to a full tank of 93 and I started getting CEL for low octane so when back to only 93 and it went away and have been using Boostane now with no problems.
I've never had a CEL. Low Octane? Don't understand that.
Boostane will wear out your plugs faster. I would check them no more than every 10000miles. E85 is easier to get. E30 runs cooler. E30 is less expensive for octane improvement. Corn.
