Chevron Techron Fuel Injection Cleaner - 12 oz, (Pack of 6)

If your vehicle has fuel injection - particularly Direct Fuel Injection, this Techron fuel additive will help keep your engine running well. It’s easy to use and costs little and I advise using it every month or so so keep the deposits down in your cylinders and injectors.

One bottle cap was loose leaked in package

It would really be wonderful if a set of instructions were in English

Not as good as the concentrate plus but less expensive. I like to let this and similar product get sucked thru the brake line directly in the combustion chamber to hit carbon deposits, cylinder chamber, plugs and injectors rather than mixed with fuel and pulled thru the system. I wouldn't do this repeatedly too much but once every 3-5k miles is a great idea, especially if you have direct inject (GDI).

Arrived in what appears to be Chevron Lubricants official box of 6. However that box and all six bottles are labeled completely in Spanish and for export to Mexico. I read Spanish but I wonder if these are out of date items. From photo you'll see tracking numbers on bottles rubbed off (likely naturally as the bottles touch in that spot) and on the box you'll see a date of 27 July 2021 - it's almost 2026 now (Nov. 2025.) Just beware
