Can’t say for 100% but feels it worked!
Neil Morgan –
Excellent product, gas mileage improved with the first tratment.
Springer Pup –
Works well in small equipment, pressure washers, lawn mowers, etc. to keep that fuel system clean and working. A small cost to avoid bigger problems, especially with the quality in today’s gas.

I’m a long-time user of fuel treatments. The good ones really do work to maintain good fuel mileage and a good idle. I’m aware of what are reputed to be and seem to be the two (maybe three) BEST brands. Chevron Techron is one of those brands. This is my first purchase of the High Milage version, but one assumes it is just a more concentrated offering of the usual product.
All About The Journey –
The fuel gauge on our 2006 Toyota 4Runner was not working properly. After refueling, the gauge would sometimes read full, sometimes half full. It was very erratic. After using the Chevron fuel system cleaner on two fill ups, the gauge started working correctly again. It’s been over a month and the fuel gauge is still working correctly. I’ve ordered a couple more bottles for future use, if necessary.

Chevron Techron came on my radar decades ago when BMW said, in their research, it helped prevent deposits on valves. I add a bottle to my tank only occasionally, and usually shortly before i’m planning to do an oil change to help clear any deposits.

The only one used in this household. Does the job as stated in all our high mileage vehicles. Chevron comes through again.
