I have a Dodge Grand Caravan 3.3 l engine with 180000 kilometers (20000 miles). I used (several years ago) the B12 (0120) with amazing results. I see that you now offer the Berryman® B-60 High Mileage Fuel System Rejuvenator. Which should I use? Will the B-60 (#7516) do what the B12 (#0120) can do?
