Advance Auto Parts offers the Chevron Techron Concentrate Plus Complete Fuel System Cleaner 12-oz. Bottle
, model no. 67740, for $4.99
. Choose in-store pickup
to avoid the $9.99 shipping fee. That's the lowest price we could find by $3, although we saw it for $3 less via rebate hassles in June. It treats up to 12 gallons of gasoline.
Of note, Walmart offers a 10-oz Bottle
, model no. 266361-338, for
$4.94 with in-store pickup. Although a smaller volume, it's purported to treat up to 15 gallons. (Note that the manufacturer currently recommends to use 1-oz. per gallon for this cleaner, so it's unclear if the Walmart unit may be a different formula.)
