Chevron Techron High Mileage Fuel System Cleaner, 12 oz, Pack of 1

Have been using this product for years. Dissolves carbon and cleans fuel injectors. I know this because after about 100 miles of adding this to my tank a piece of carbon wedged itself between the gap in two of my spark plugs. Truck began to run very rough so i R&R'd all my plugs and found the carbon in 2 plugs. Also use it in a motorized bike and 2 outboard motors. I think its better than Seafoam for automobiles. Just my opinion.

This is the gold standard of fuel system cleaners. I am a mechanic. I swear by this stuff. It uses higher amounts of PEA than other fuel system cleaners. If you don’t believe me, just look up The Motor Oil Geek on YouTube and listen to his testimonial. This is an American product that outperforms the rest, including Red Line or Liqui Moly. Red Line is also a great product. But this is cheaper, and better. You only need to add this to your vehicle’s gas tank every 3,000 miles, so it isn’t expensive if you consider that. I personally do add it to the tank more often (when finances allow) because of the increased fuel economy I notice. I’d you want to keep your vehicle running in top shape in these tough economic times, look no further than Chevron.

My old car wouldn’t pass the CA smog test ; dealership said repairs would cost me $3000 / no guarantees . Short story ; i have been using this and it cleared the carbon buildup & passed smog 👍

Recommended by nearly every reviewer and I find my car running smoothly, less sluggish at stop and go. The additive may have solved a gasoline quality issue. I intend to use it every year.

There is no alternate universe where you can test your vehicle's performance over the years using this product, versus not using it. But as my car passes the 130,000 mile mark I feel the need to do as much as possible to keep it running smoothly. While there is no single standardized, independent "seal" from a third-party testing agency (like the EPA or an independent lab) widely published for public viewing, the formula relies heavily on Chevron's proprietary Polyether Amine (PEA) technology. Independent mechanical testing and user feedback provide robust evidence of its effectiveness. Automotive experts and mechanics have conducted before-and-after endoscopic testing on high-mileage engines. They verified that a single treatment of Techron High Mileage Fuel System Cleaner significantly removes carbon crud from combustion chambers, cylinder heads, and intake valves. Product reviewers consistently report reduced engine hesitation, improved idling, and restorative fuel economy (often 2-4 MPG gains). Experts on enthusiast forums frequently discuss the base chemistry. Users and mechanics universally advise applying one bottle to a near-empty tank, then filling completely, typically doing so every 3,000 to 5,000 miles.

Quick shipping and a very nice product!

Got a 10 to 20 year old, 75,000+ mile, 87 octane (cheap gas) commuter car? Keep it running clean by making your own Chevron/Texaco Super Supreme gasoline. One bottle plus one tank of any 91+ Premium octane gas (cheapest you can find); do this every 3rd tank.

Great stuff if you own a C5 Corvette. Helps with the fuel gage sticking issue.
