What are the differences between these two types of Techron ? All that jumps out is the high mileage bottle contains 2 oz. more liquid (12 vs 10) and some silly claim to stabilize fuel for up to 24 months (who cares about having a 2 year fuel stabilizer in Techron ?) … I want to hear that the high mileage version has more PEA or some other stronger add pack to better clean up high mileage engines than regular Techron.
