Chevron Techron Concentrate Plus Fuel System Cleaner, 12 oz, Pack of 1

I’ve been using the Chevron Techron Concentrate Plus Fuel System Cleaner for a while now, and I’m honestly impressed! My car was starting to have rough idling and sluggish acceleration, but after using this cleaner, it runs like new. The fuel system cleaner helps clean the injectors, combustion chambers, and intake valves, which noticeably improved my engine’s performance. It’s easy to use, just pour it into the gas tank, and you’re good to go. I’ve noticed smoother driving and even a slight improvement in fuel efficiency. Highly recommend this for anyone looking to boost their engine’s health!

Excellent fuel system cleaner! After using Chevron Techron Concentrate Plus, my car runs smoother with improved acceleration and fuel efficiency. It effectively reduces engine knocking and cleans injectors. Easy to use—just pour into the tank before refueling. Highly recommend for regular maintenance. Works better than other brands I’ve tried. Five stars!

Great Product. Very Noticeable increase in acceleration and smooth- running engine. Highly recommend this product be used at each oil change. No Tools required. Just pour it in Gas Tank that is less than half full.

This stuff actually works, showing an immediate increase in fuel economy in both of the cars we put it in.That said, ALL 6 containers came with loose lids and foil seals that weren't attached. Half the shipping box was thoroughly saturated. I can understand one, but all 6 bottles? I'd give it 3.5 stars purely because of the leakage.

Was told by an engineer chevron and shell were the best gas to get for older vehicles. Although I am not hot rodding, I notice a small difference in speed and which I believe it is cleaning more of the pieces inside the engine. Overall I think it is holding up well as I used to only buy the cheapest gas. The color is clear and smell are what you would expect from gasoline and overall I think it is working well. In this day and age we want the best value for our money, so why not try it, it could save you some money down the line!

works well at keeping the injectors clean

I bought a 72,000 mile used Camry, 2.4L classic engine, with good service as shown on Carfax. I live in California so our cheapest gas has twice the Federal required level of detergent in it. Top Tier brands (Google search for Top Tier Gasoline) has 4 times the Federal required level of detergent and is available country wide.So there are 3 levels of detergency: Federal; California minimum; Top Tier branded gasoline (ARCO, Shell, Chevron, 76, most big brands).It’s impossible to know what kind of gas went into my recent used purchase. I’m assuming the cheapest, which - except for Costco - means California minimum, twice Federal minimum though.My new used car ran fine. Maybe a little rougher at idle than it does now, 1200 miles later. Since I got it, I’ve been running a 12 ounce bottle of Techron at each fill up. Tank holds 14 gallons but my fills have all been between 9-10 gallons.I have a certain consistent route about 40 miles outbound and inbound, free flowing freeway traffic. Very consistent route to freeway. Very consistent morning temperatures during warmup.I have seen my route change from 28.5 mpg, as indicated on the dash computer, to 30.3 mpg.I am finished with my “cleaning cycle” and will henceforth only purchase Top Tier fuel, which. should be sufficient (the car makers validate their clean air systems on Top Tier fuel) and add a bottle of Techron at each 1000 mile odometer point (on my cars purchased new I don’t add Top Tier ever). I am hoping to gradually and gentle clean up any valve and piston top deposits.You’d think by now, the main ingredient in Techron would be available in a $5 knockoff. Sadly the competition uses old snake oil ingredients from the ‘50’s and ‘60’s. Techron is the real deal.

Excellent fuel system cleaner! After just one treatment, my car runs smoother with improved acceleration and fuel efficiency. It effectively reduces engine knocking and cleans injectors. Easy to use—just pour into the tank before filling up. Highly recommend for maintaining peak engine performance. A trusted product from Chevron—worth every penny!
