Easy to use

Did what it says it does...great product..easier motor starts and quieter and smoother running....

A short story long---LOL---My zero turn started acting quirky-it would not run at full power and would begin to stall when put under a full load - like trying to mow some taller or thicker grass- never did stall since I would immediately kill the mower but obviously it was not right. I checked and changed the fuel filters-this one has 2 . One in the pick up line in the tank and one is inline just before the fuel pump unit. No help! So, before I dropped the big bucks to have the local farm dealer come and pick it up (at $75 per pickup and return) plus h=whatever shop charges that would result I thought "What the heck, lets give this stuff a try" I gambled $6 . I put in 5 ounces for the 5 gallons tank, and filled it with the gas I had on hand- should have been relatively fresh gas -no more than 2 weeks since pumped . Well, whatever the cause of the issue within about 15 to 30 minutes of low speed running- mostly at idle - the engine seemed to be idling smoothly as opposed to before where it surged but never died, I gave it a try at mowing. YEA!!!! full power and no bogging down - I finished mowing the yard and a part of the pasture (not yet grown up much so it is not requiring the rotary cutter YET) My only guess is perhaps a batch of either old gas or some water in the gas can or mower tank but whatever the cause it fixed it --and all for $6.

Works well

I damaged one of the mower spindles early in the spring of '23 and then never got around to fixing it. The gas had Stabil in it but the engine ran rough (bad), especially when engaging the blades after repairing the spindle. After draining as much of the old fuel as I could this spring, I used two kinds of Seafoam, the spray straight into the carb and then a high concentration of the Multi-System Additive into the fuel. The engine spit and sputtered for a good two minutes and then smoothed out. When engaging the blades (more load) before the Seafoam, the engine would almost kill and then backfire and run even rougher. After the Seafoam, that didn't happen. I'll never use anything else.

I have used this and Seafoam regularly for many mowers that I have found discarded on the side of the road. I drain the old gas from the tank and bowl, refill with fresh gas and this product. Squirt the carb with starting fluid and get it running. It may be rough running at first but it eventually smoothes out. I also use it for my mowers every spring. I love this stuff and highly recommend it.

Just what i was looking for.

I use it as an additive for my small outdoor equipment engines , works great.
