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

I was told to use these one every oil change on my new Kia 2022 K5 and my engine literally every time I put this bottle in runs like new again and it maintains it throughout the 3,000 miles if not longer knock on wood so far the stuff is really amazing. Huge advantage of the line especially with engines with GDI that have direct injection of fuel. Especially good on turbos and superchargers this stuff really works amazed I've been using it for years I just had time now to do a little small review but it is really good stuff

I have 3 vehicles model years 2006, 2013 and 2021. I used the Chevron fuel injector cleaner as routine preventative maintenance. I believe adding this and keeping up with the auto maintenance keeps my vehicles in good working shape.

I use this things in all my cars. Even the ones running e85 in order to keep everything working as it should. Some of my friends started using it too and they are happy

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.

Ive got 4 cars in my family so this helped take care of them all with an affordable price. Very quick and easy to use and protects my engine.

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.

USED IN THE PAST AND CONTINUE TO USE TO CLEAN INJECTORS AND REMOVE POTENTIAL BUILD UP OF CARBON ON VALVES...EVERY 5000 MILES

I'm a long time user of Techron fuel treatment. I put them in my 2014 Volvo XC60 once every 60 days and I definitely see an improvement when using it.
