Slick additive that should help with friction.

I have a 5 quart vehicle and it was easy to calculate that 7.5 ounces were required. I put the fluid on my fingers and it feels very slick. Making oil operate more slippery is a great idea and I am excited about this product. It also came really quick and was well packaged. Walmart provided consistent updates on the delivery process.

Seems to work.

It seems expensive for an oil additive but if you follow the directions of 1.5 ounces per quart of oil you can get two oil changes from one bottle so that does make it a little more comparable. It does seem to help with engine friction and I bought it specifically for my 2006 F250 with the 5.4L Triton engine because this engine is famous for oil related problems. So far, so good

Impressive Performance Boost in a Small Bottle

I've tried a few fuel additives before, but the Molecure FM16 Fuel Additive (16oz) honestly stands out. After using it for a few fill-ups, I noticed my engine running smoother and quieter, especially during startup. Acceleration feels more responsive, and the overall drive just seems more refined. One thing I really appreciate is how easy it is to use — just pour it in and go. No complicated steps, and it mixes well with the fuel. I also like that it's designed to help reduce friction and wear inside the engine. It gives peace of mind knowing you're helping protect important engine components while you drive. I've seen a slight improvement in fuel efficiency too, which is a nice bonus with gas prices these days. Whether you have a daily commuter or a vehicle you want to maintain long-term, this additive feels like a smart addition to regular maintenance. Definitely something I'll keep using to help my engine stay in top shape. Highly recommend giving it a try!
