Chevron Techron High Mileage Fuel System Cleaner, 12 oz

This is something you HAVE to do every 3K miles on any modern direct fuel injection (or any other) car to avoid expensive repairs. This keeps your engine running smooth, cleans the entire fuel system (gas pump, gas lines, injectors, etc.) so it doesn't clog or anything. If you haven't done a fuel clean up in a while you will notice the difference. Then keep on doing it.

I use this.I started using this because the brand I was using previous to this.I don't know, it just seemed like something had been taken out of it.It wasn't working as effectively. I read recommendations online because I always try and find out as much about something before. I buy it. This seems to work fairly well. I have an older car. It has high miles. I constantly try and keep my fluids up. That's what I was taught when I first started driving. No matter what vehicle you have, won't you know the condition of it? And you keep it up, you always keep your fluids up. So as cars get older, sometimes they need a little help in terms of keeping the pistons. Clean the just all of it, gas pistons, everything. So I use an additive, and it usually helps the car. Sometimes when it's a little bit slow and sluggish, it helps to clean Oh, and give the car a little bit more power. I should buy it more regularly though. But I don't always get a chance to get the online order or else myself up there. I would recommend this to try because it's right now to roll back price. Even at the regular price, it's still reasonable. It's not quite 16 oz. It's 12, which is still okay, but it does work if you're having severe in all sluggishness before you dry and find out about your transmission. I would try 2 bottles. Maybe not all at once and try and make sure your tank is close to empty as possible. Because you want to be able to With this particular brand try and get it into the system. Is, you know faster and if your tank is full, it's gonna get in there. But it's going to, you know, be a little bit more not diluted, but it's just better. It's faster, so yes, I'd recommend it. I buy it still. I just bought some just a couple days ago. I should have bought 2 bottles cause I hadn't been driving for a while. I'm a little bit sluggisher, but it's a very good brand it helps the car get along and as your cars age. You need help. At least the cars that were made before they started making these high bird and electric battery cars. If you have a normal gas car, then as the years gone, it's going to need a little help. So Give it a try.This brand may help you.I'm not guaranteeing it because different brands sometimes do different things for different cars, but I would recommend trying it

I like that it has helped clean the fuel system. I no longer have stalls. It did take 2 tanks full and 2 bottles of the Chevron cleaner for this to have a change. I plan on adding it to my tank 2x a year for maintenance. I have 85K on my car and it requires 91 octane so having an improvement even for the cost of the cleaner is well worth it.

I've used this Chevron product for years . it is one of the fuel system cleaners that you can actually tell the difference in your vehicles performance. This is great to get better gas mileage , especially now that gas prices are so high. Just open the container and pour in your tank Thats it ! Keep or regain that lost performance and mileage by cleaning your fuel system. Great product , which I highly recommend.

Chevron Techron High Mileage Fuel System Cleaner is one of those rare products that actually delivers on every promise. After trying countless fuel additives over the years—many of which felt like pouring money straight into the tank with no results—this is the only one that produced a real, noticeable difference. The engine runs smoother, acceleration feels cleaner, and even the idle becomes more stable after a single treatment. What sets Techron apart is its ability to break through carbon buildup and restore performance in high‑mileage vehicles without gimmicks or exaggerated claims. It simply works, and it works consistently. Compared to the long list of additives that do little more than lighten your wallet, Techron stands alone as the product that truly earns its reputation. If you want something that actually improves your car's performance instead of wasting your money, this is the one to trust.

I've spent the last 20 years trying all the many brands of fuel additives/cleaners (including the professional "kits" supplied only to auto repair shops), and the clear winners are Techron and Redline. Techron costs less, so now I use it regularly. Just one bottle of this stuff can fix problems you would never expect. I once had a car failing federal emissions testing with an OBD code for Transmission Range Sensor malfunction. One bottle of Techron in the tank, drive about 150 miles, and boom, passed the test. Rough idle? Could be caused by a lot of things, but always try a bottle of this before taking apart the engine.

My car is now 24 years old. And I keep up with all my cars needs. I filled up with gas which out here in Cali is a bank loan needed at times. The next day I had a doctor's appointment and glanced at my gauge and sitting in my garage over night I was down a 1/4 tank. I knew my dogs had not taken my car out for a pup cup so I took it to my mechanic 🧰. He told me to first try Techroline. So I just put it in after Church this morning. I'll see if my gauge returns to its normal carefree floating position after 2 uses of it. If it does it will save me over $300 for a new sending unit for the gas tank. Walmart only charges just over $10 which is still much less that $300. Even in this mathemathilly challenged days. So I will do this again when I need gas and let you know if it works. I guess out here with gas over $4.50 a gallon buying on a good day giggles. Chevron gas today was $5.59. I am sure it would not hurt but help. To keep everything clean and sweet smelling under the hood. Ok I will let you know and as they say ... Film @11. Blessings...

Used this as directed in my 2013 high-mileage Mitsubishi Lancer. This is seriously the only thing I will use from now on as a fuel additive. It is well worth the money, cleans as it says it does. It should, it is the OG and really does the job. I highly recommend this for anyone who has a high-mileage vehicle. Follow the directions. You do not need the whole bottle! It tells you how much to use, and you have a nearly empty gas tank.

I have been using Chevron Techron products for over 10 years now on my many European cars, and must say I have nothing bad or negative to say, only good and positive results for me and my cars.

After putting this in gas two times truck started to make a weird noise now it's less often after a couple of gas fill ups now makes noise when gas tank is full then after driving 50- 100 miles it goes away
