Did the formula change? does this no longer contain pea?

Per ITW Global Brands response 7-17-23, "Multi-System Tune Up fuel additives contain CarbonClear which is the most advanced P.E.A. All our Gumout fuel additives contain equal parts PEA."

Is the shipping time of one to two months accurate?

I don't know. It would depend on the seller. Seems like a long time. Walmart delivery is like two days.

How often do I have to add this product to my vehicle’s gas tank?

Add it in every 2 to 3 fill-ups. It will probably take six months or more before you start noticing a difference. But, your gas mileage will improve, and your engine will run smoother. Just give it time. I went from 12 to 13 miles a gallon all the way to 18 to 22 miles a gallon today. It works!

How often can you use this product?

I've been using is for many years. First time, put an entire can in your fuel tank when you fill up. After that, I put about 1/3 to 1/2 with every fill up. I use it in my tractors, mowers, gas leaf blowers and edgers and boat. Since the boat sits up all winter without running, I usually put 3 cans in the tank the last time I run it. In addition to cleaning the entire fuel system, it also stabilizes the fuel so it doesn't break down and turn into lacquer. Also, if you buy fuel with ethanol in it (most gas has 10-15% ethanol in it), Gumout helps keep it from turning into a gel like substance in your fuel line. Ethanol comes from corn and soybeans, so if you leave it in fuels line without a product like Gumout, it can set up fuel related issues. Hope that helps! Eddy
