The ventilated design with a front vent mesh insert is particularly important for bikers and skateboarders who are out there doing their practice on warm weather days. Comfort padding protects your brain during inadvertent accidents on varying trail conditions.

3rd Update! See review... Good stuff and works as advertised...
Update - 3rd oil change/flush. Engine oil draining from engine is waaaay cleaner than my first flush. Probably won't need to do a 4th time for several changes. I added Ceratec at this change and am amazed how much better the engine performs since my initial flush. Less clatter and very smooth idle. (Jeep 4.0 I6) Update- 2nd change and used the flush again. About 7000 miles from first use. The oil was cleaner and less "gunky" as first time but oil was definitely dirtier than normal. Right away noticed off idle throttle response improved. Then on a drive I take regularly with a mountain pass and long downhill I noticed that even tho the jeep downshifted out of OD it took much less throttle to hold 65 up a long grade. On the downhill normally I would see 50-60 mpg max on the digital readout. This time. It went to 99 which to me indicates more vaccum below the throttle plate. My guess is the rings freed up a bit more than the first flush and highway mileage is up to 23+ where I would get 21 before. Nice! Used in 2001 Jeep Grand Cherokee. 140k miles and a ticking lifter (common in the 4.0 - 6 cylinder...). Definitely cleaned sludge (oil filter very heavy!) and oil was dark when draining. Idles smoother, oil stays cleaner longer, slight oil pressure increase and runs cooler. The lifter still ticks but probably a cam lobe issue. Will use it after 7500 miles or 1 year. Will report back after next change.

Tips and tricks
I watched several videos by professionals who used this. Follow instructions. Make sure the engine is warm before you put it in. Make sure you have everything you need. The biggest tip I got that was repeatedly emphasized by the pros was to buy a “cheap” oil in addition to the new oil. After you run the flush drain the oil and flush. Put the cheap oil in and “rinse” the inside of the engine with the cheap oil. Then drain again. Replace the oil and filter with your good stuff. I followed these instructions or suggestions and…. I sat in the truck while the flush was running. It’s a 13 year old truck with 150,000 miles. It was running strong but burning oil and kind of loud. Sounded like it was growling. There were some ticking type noises that made me nervous. As I sat in the truck and let the flush cycle through the engine at idle I could literally hear the flush working. Very slowly it was like someone gave the engine a Xanax and you could hear it getting quieter and calming down. I drained, rinsed with cheap oil only letting the cheap oil run through at idle for another 15 minutes then drained again. The oil flush was clearly important. It didn’t come out as black as the first drain but it looked like old nasty oil. The truck is no longer burning oil. My gas mileage has increased significantly and it is running so quiet and smooth it’s unbelievable. I used a little less of the liquid Molly flush than it called for regarding the flush to oil ratio. I didn’t want to do something too intense to the inside of the engine. But the results were remarkable. Just as advertised after following the instructions. I also added the liquid Molly oil additive to the final oil change to ‘lube’ the inside of the engine. I plan to do another flush in about 10,000 miles. All that to say, yes, you won’t be disappointed as long as you follow instructions and a few tips and tricks. My truck is almost running like a brand new truck and again it’s an old and tired truck. I will use this as part of a high mileage maintenance and perform the flush every 50,000 miles or so. I feel confident it will extend the life of my engine based on the results

Seems to have helped
Bought a used 2020 Jeep Sahara 2 liter turbo charged with 80k miles from a dealership. Dealership had just changed oil the day of purchase. Drove it home 30 miles down interstate and another 20 back roads, it ticked and tapped allot at idle and the dip stick was varnished. I added the flush, let it idle for 10 minutes and drained it. The new oil from the dealership drained out jet black, no light could pass thru it. I changed the oil with Walmart oil and a cheap oil filter and let it idle for 5 minutes to clean out all the engine flush, it drained out clean and clear. I refilled it with Pennzoil Platinum High Mileage oil and a Fram Ultra Synthetic oil filter. It's been a week and the engine is noticeably quieter and smoother since using this product. If nothing else it cleaned allot of carbon from inside of my engine.

HOLY CRAP!!!!
So my 2005 Durango has a 5.7 and I put on 253,000 miles on it before it blew a head gasket. Since it was summer, iI decided I'd tackle it myself. The upper end was so full of gunk, I can't believe I hadn't had serious issues. Anyway, I apparently dropped some pieces of crud down the oil channels, 'cuz after putting it all back together, I got alarms for low oil pressure. Figuring I'd try anything else before replacing the oil pump, i gave this stuff a try. WOW!!!! Not only did the oil pressure return, the engine runs SO much smoother! I had forgotten how smooth it ran when it was new. The caveat is that apparently the gunk was the only thing keeping some areas from leaking - as it lost oil at a startling rate. 1 bottle of the Liqui Oil Saver though, and within a week the oil leaks completely stopped.

Awesome!!
Had a check engine light come on for cam shaft position. Did some research online about the specific code and found that I could be due to sludge in the engine. Added this and ran for about 30 minutes and then had the oil changed. The light never came back on and the engine is running smooth and quiet. Will definitely use again.
