Advance Auto Parts offers the Chevron Techron 20-oz. Fuel System Cleaner
, model no. 65740, for $6.99
. Choose in-store pickup
to dodge the $9.99 shipping fee. (Amazon
charges the same with free shipping for its Prime members.) That's tied with our mention from three weeks ago and the lowest price we could find by $5. It's designed for carbureted or fuel-injected spark ignition engines.
