Super impressed! The product arrived within two days, and Techron continues to be my go-to for keeping my car running smoothly. I’ve noticed real performance benefits, and being able to buy it in bulk makes it even better. Great value and great product!

Good for car with gas engine.

Restores power and increases mileage!

12 oz — I thought it was a good deal. Each bottle only treats up to 12 gallons of gasoline. The 10 oz bottle at Walmart treats up to 15 gallons of gasoline. In both scenarios, you end up spending about 55 cents for each gallon treated. These bottles are very likely less concentrated.

The product is great, but every single shipment I’ve received leaked during shipping. The box is covered with the product and it has strong odors.
