Review: Worth Every Penny - I have two vehicles with over 200k miles (01 jeep xj & 2008 subaru outback) and this stuff keeps them running good. It’s so cheap.. if you go get an oil change, they’ll charge $85+ for this service. It takes less than 60seconds to do it yourself! I keep a few bottles around and recommend it all the time. it also cleared my engine code on both of my vehicles 🤷🏽‍♂️ Review: Works as described and needed - Ethanol sucks and this product doesn’t make a dent in the Midwest. But, when outside the Ethanol zone my Jeep Wrangler gets better mpg than what it’s suppose to. In California got 23 mpg plus highway, and similar on the east coast. With electric cars I’ve read that it’ll dwindle corn fuel to a lost industry. Let’s hope so. Not worried about my Jeep as gas cars will still be present. Just a mix of hybrid and electric. It’s just for fun. And is. I don’t drive much. Use the motorcycle. Buy the best gas. But sometimes the only choose is corn fuel. Mostly do highway travel with the Jeep. I’m not in it for high mpg. But at least 20 plus highway when I use Ecco and cruise. When I hit 23 plus couldn’t believe it. At the moment driving to the VA on the highway at at 17.8. WTF? I’ve got this product on sub and save so happy it’s in stock and arriving next week /\ update 2nd purchase. Does a great job on road trips boosting miles per gallon and keeping the engine running smooth. Will repurchase ⭐️⭐️⭐️⭐️⭐️💯 Update /\ First time in a year since COVID I’m driving more than twenty miles a month on average with the Wrangler. Headed to Nashville area to visit family. Didn’t wanna go to the auto store so popped online to order and have some delivered. I used half for the first tank of gas and the rest during the first fill on the 1200 round trip. It’s for up to 35 gallons is why I divided it. Went from about 16 mpg back to normal 19 to 20 highway. I have used products similar to this for decades to help the engine for all reasons described. Typically don’t spend quite as much on fuel treatment, but with gas prices at their current level and the fact the Jeep sat a lot for a couple of years except for local driving dipping through normal mpg of 20. Figured a an intense product would be more helpful then regular gas treatment. Plus, gonna start riding the motorcycle again. Took a break during COVID. Wanna keep the Jeep in top engine function shape. In case you’re wondering, 2016 Wrangler. Based on my experience with a variety of products am happy with the results of this product. The engine runs great and the mpg is returned to normal after about 300 miles. This is less then two tanks of gas from about 16 back to 20 mpg. And, remained at this level all the way back. At the current gas prices am very happy with the improved mpg so quickly. Another reason I use gas treatment on trips is in case bad gas is sold. I stick with recognizable companies over cheap gas from an unknown. The app Gas Buddy was super helpful, too.
