Chevron Techron Concentrate Plus Fuel System Cleaner, 12 oz, Pack of 1 12 Ounce (Pack of 1) 12 oz.
Overview
Chevron Techron Concentrate Plus is a concentrated 12 fl oz (355 mL) fuel-system cleaner engineered to remove deposits that build up on injectors, intake valves, carburetors, ports and in combustion chambers. It’s intended for gasoline engines and is formulated to work in a single tankful for most passenger vehicles, helping restore lost power, smooth idling, and better throttle response. Use it as a preventative every ~3,000 miles or as a corrective treatment for mild to moderate deposit-related issues like engine knock, ping, or rough cold starts. Ideal for drivers who want a proven, no-frills maintenance product to keep fuel systems clean and preserve fuel economy without a shop visit.

Cons
