More Octane, More Boost, Lower ETs- a single-use fuel additive that increases the octane level of fuel in the tank.

NOS Octane Booster can provide the extra edge you need when the chips are down. Like pouring Nitro in your gas tank, it allows forced induction engines to run more boost safely, so you don't encounter the engine's detonation threshold. It's also especially beneficial in high-performance, turbocharged and high-compression engines running on a track day. This single-use fuel additive boosts octane up to 5 numbers, which aids in reducing knocking or pinging during combustion. Engine knock occurs when the fuel/air mixture ignites prematurely, leading to retarded timing and a drop off in engine performance and fuel efficiency. Over time, this can potentially damage pistons, valves and cylinder walls, NOS Octane Booster facilitates smoother, more stable combustion that expands the safety margin in engines that demand higher-octane fuel

Features:

  • Boost Octane rating up to 5 numbers
  • One bottle treats up to 20 gallons of fuel
  • Reduces NOX, Hydrocarbon and Carbon Monoxide emissions
  • Extends detonation threshold to eliminate engine knocking and pinging
  • O2 Sensor safe formula
  • Intended for off-road use only

A waste
Color: White/Silver-Tone/Digital
If I could I would give it zero stars. It was running when I received it so who knows how long the battery has left. No instructions were included. The setup is impossible unless you’re into computerized “smart” crap. I looked up how to do that and it’s way too involved for a watch to tell me what the time is. I don’t want a personal dictator, I just wanted a watch I could wear and know what time it is. Too much hassle to return. It’s going in the trash. Total waste of time energy and money. Zero stars.

Favorite Watch
Color: Black/Silver-Tone/Digital, Color: Black/Silver-Tone/Digital
I have been using this same kind of watch for 10+ years. I like the belt like strap and the small size. I also appreciate how it has a light on it, the date, and the stop watch. I haven’t had any issues with the battery. These watches have held up well for me although I try to avoid getting them wet. The buttons are hard to press when you first get them but get a little easier to press over time. I still have issues remembering how to change the time and typically have to look up how. The silver parts on the front do wear out over time and turn copper colored. I wore one of these watches for around 5 years before buying a new one when the band which holds the excess space from the band broke. Attached is a picture of the watch that I wore for at least 5 years and a brand new one that I bought.

hard to read display, no manual included.
Color: Black/Black/Digital
I haven't decided yet whether or not I will keep the watch. Problem is there is no instruction manual attached and you cannot find one online. However if you call Timex support they will email you the manual if you give them the model number which is included in Amazon's product description. However even with the manual watch is very hard to set. It lacks some functions normally Timex has like time can only be set up there is no down button. And most importantly display is minuscule. So it is really hard to read to set. Watch is a ladies watch. It is small and I like it a lot. But buttons are hard to operate and it is hard to read.
