Used it in my Lincoln pickup before plug change. All came out easily with no trouble. Original plugs with 200,000 miles.Saved me over a thousand dollars.

I was experiencing some sluggish starts as well as sluggish acceleration. After running this through I haven't noticed any of the sluggishness and it has been a month now since I put it through my vehicle. Stuff works great.

I am trying in one vehicle - But I would encourage you to read up on articles and blogs.It is either the greatest thing since sliced bread or not worth the money.I had several questions about the product contacted the company - After 2 months no reply - Not a good sign.

3.0 out of 5 stars NOT DISSATISFIED!!!

3-Star rating does NOT indicate any unhappiness with the product. I used 44K (4-cans) in the 80-gal tank of a 2011 motorhome (gas, not diesel). The Ford V-10 engine only has 25,000 miles on it so my expectations for a huge improvement were minimal. So why did I spend the $$ and use 44K? Two reasons: 1) The motorhome is in storage 3-4 months per year. Even though I use Sta-Bil in the tank prior to storage I was concerned about gunk build-up in the fuel injectors because I am not always able to find Tier 1 fuel. 2) The motorhome has an air-cooled generator that fuels off the main tank. The generator has a carburator, not FI, and for many of the reasons above (storage, fuel quality) I felt a little chemical cleaning couldn't hurt. At the end of 70-gal fuel used at 60-65 mph and about 500-miles, I can't honestly say I noticed a big improvement in performance, nor any problems. I suspect 44K may be best tested in engines of higher mileage, perhaps those not "shown love" in their maintenance schedule? For me, it was good test but no exciting results.

Helped my Harley Sportster a little. Will need to treat it a couple more times. Thankfully the can treats up to 20 gallons, so it should do the job by the time the can is done. Thank you Bolo!
