Happy Carburetors
Would RecommendThis product has saved me from rebuilding carburetors at least 3 times. It corrects rough idle and acceleration issues. It also preserves gas for storage. This product is a MUST ever since they took lead out of gasoline. EXCELLENT!!

Blue smoke gone
Would RecommendHad carbon build up on my rings which caused engine to blow blue smoke. Ran down to half tank of fuel added 2 cans to gas tank, 6 oz. to engine oil. Ran vehicle in 3rd gear revving to 4000 and let off continued this cycle for about 10 miles. Noticed no smoke and oil catch can I installed had smaller and smaller amounts of oil in it. Change oil to full synthetic and after a few weeks still no smoke and catch can only has minimal amount. Worked great for me!

Seafoam High Mileage is an AWESOME product!
Would RecommendI have a 2012 Nissan Xterra with 78,000 + miles that I use for my beach fishing here in NJ. It has been running a bit rough and the acceleration was sluggish.
