STP Ultra 5 In 1 Fuel System Cleaner and Stabilizer, Deep Cleans Fuel System and Fights Engine Friction, 12 FlOz

Have used this x2 on my daughter’s car and have seen a big improvement in gas consumption and mpg!

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/\ update2nd 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. Loves App Rocks⭐️⭐️⭐️⭐️⭐️💯

I have a 2006 Dodge Ram 1500 that I don’t drive much. At 17 years old, I only now hit 40K miles. It’s had some evap system issues in the past that was repaired. In December, I drove the truck for a few hours to run errands for Christmas. On the way home, I stopped at a gas station I’ve used before to get gas (they use detergent gas). When I pulled away from the pump, the truck died. It kept dying all the way home (3 miles away) which made for a very scary ride. No lights came on indicating there was an issue like in the past. I first thought it was the battery needing to be changed because this is what happened once before when that was the issue, but a ‘check engine’ light came on at that time. Battery was fine. For 6 months, the truck mostly sat. When we did try to drive it, it kept dying and again, no check engine light. My brother thought maybe there was moisture in the tank and advised I get something for that. I came to Amazon but had a hard time finding the product he recommended. Instead I found this STP 5 in 1 Fuel System Cleaner. I bought a bottle of it and put it in my full tank of gas. After letting the truck idle for a bit, we decided to test drive it. It didn’t die not even once. We have been driving it for over a month now, whether it be a short trip or a longer trip, and I’m not having any issues. I should have already needed to fill my gas tank back up but I still have half a tank. The truck is quickly approaching 41K miles. I’ve bought 2 more bottles of the STP 5 in 1 and 2 bottles of the STP Fuel Injector Cleaner just in case I need it the next time I fill up. I don’t know what exactly the STP did to my truck (I suspect it cleared ethanol build up but can’t confirm) but thankfully for the time being, it has saved me a trip to the mechanic.

Works great. Only problem is the bottles I received only treats 26 gallons instead of the advertised 35. Not a big deal though since I ordered 2 and my truck has a 36 gallon tank. There was another review that had the same problem as me as well. Overall, great product.

I have been using this fuel additive on 2009 Honda for more than a year. The car rides smoothly, thank God. As they say, “An ounce of prevention is worth a pound of cure.” It works great.

Me gusta ponerlo en el tanque de gasolina, cada vez que hago el cambio de aceite. Es súper bueno

Pouring a bottle of this solution into my gas tank turned my check engine light off! I've driven it for about 50 miles since, and the light is still off. This product is exceptional. If you are experiencing performance issues with your vehicle, you need to purchase this product. 10 stars!!!!

My 2002 Toyota Sequoia was badly sputtering every time I stopped at a light.It was unnerving... but before going to a mechanic, I decided to go the cheap way and I added this product to a full tank of gas.I swear this was short of miraculous. Not a single sputter again!I drove out of the gas station with a "new" car! It's been over two months now and today I felt a little "sput sput" again now and then. Nothing major, but I'm buying this product again before it gets as bad as before.Very glad I found this before paying a costly visit to the mechanic.
