Product Questions & Solutions
I have a 2006 Nissan Murano 3.5 engine with 213000.0 miles that had a rough idle so I tried two other products and notice little difference, I remembered this product from many years ago, purchased 2 cans and added both cans to a full tank gas, it has a 19 gallon tank. After driving the first 100 miles I notice car idling very good and it had a lot more power. I was so impressed the performance, I also added 2 cans to my 2009 Chevy Silverado 5.3 with a 25 gallon tank and 132000.0 miles on that engine and gotten the same results. I can say there is a increase on the car from 18 mpg to 20 mpg on the interstate and my truck also had 2 gallon gain also. I’m very impressed with this product, So I wanted to share this with my family and friends…PS..MLS is a believer…it works… 1-13-21
I was looking for a fuel injector cleaner to treat a rough idle on my 2010 GMC Sierra. There was 30 products to choose from at my auto parts store. I decided to get Berryman’s because it was the only one in a metal can. I figured if it needs a metal can to contain it, it must be strong. I bought 2 cans. The first can straightened out the problem. I recommend to everyone and everyone has called me back to say thank you. I had a neighbor who did not drain his gas in his lawnmower for the winter. In the spring, he started it up and it was surging and would not rev up. I put about 2 ounces in the tank and told him to just let it idle for a while. Within a half hour, it stopped surging and ran like a champ. I now treat my lawnmowers with it. At the end of the season I put 2 ounces in the tanks and let them run until they run out of fuel. In the spring they start with one pull. I just noticed that my truck was getting 18mpg on a route that I take twice a week. I just put a can in and ran the route and got 19.5. With an increase of a 1 and a half mpg, X 100 miles, the stuff pays for itself. I now use it to clean throttle plates with a toothbrush. I love this stuff.
Used it in my mothers 2005 Nissan Altima, without it car misses and has P0301 truble code, started using an miss went away and check engine light went off.
I have a 79 Suzuki GS850g. Started to lose power while running and stalling out. Was going to get a carb rebuild, but tried the Sea stuff to no avail. Decided to try this product. Used 15oz in about 3 gallons of gas. Bike was running smoothly within 1/2 an hour. Would 100% recommend and will continue to use.
My grandson added a couple of ounces of B-12 to his 1997 Sea Doo that was stalling and hesitating. Amazing results in only about 5 minutes of run time on the water. I’ve never seen anything work so well; so fast.
