zMAX Small Engine Formula 6oz, Single Pack - Engine Treatment to Reduce Carbon Build-Up and Corrosion - Micro-Lubrication for Gas or Diesel Engines - Lubricates Metal Improving Efficiency

Use in my small engines, leaf blowers, chain saws, garden tractor etc. Use the approximate measuring style to add. Works great and and I believe makes starting easier and helps prevent engine lock ups.

I don't think anyone can say how well these things work, but I've been a fan of zmax products for a lot of years. I recently got two new generators and a new push mower, bought this stuff to run thru them in hopes they'll last a long time. Fingers crossed.

Everything shipped fine, no damages nothing missing… Perfect!

great product and excellent pricing

Zmax is the best there is nothing like it. Amazing results. Engine runs much smoother. Would never trust anything else.

It improved gas mileage!

I've used this product before and is a good product, but the bottle was shipped without a lid which as soon as you open it there is no way to close back up. I know not a big deal, but I don't use the entire bottle all at once. This one bottle covers several gas jug fill ups so it needs to be able to close up. Again, not a major deal, but it's becoming more common receiving mail order shipments with bad packing which causes issues with the contents.

Tried this in small engine and now it won't start have to bring it in to get it serviced not trust worthy stuff better off getting actual break-in oil that says (break in oil) I am almost certain ammsoil has it. Some put marvel mystery oil or Lucas stabilizer.
