A few years from now, we will wish we'd jumped on the 0w5 bandwagon in the "early" days.
Seems to me that oil are trending lighter and lighter. This just may be ahead of its time, like the Tucker Tornado.
I think all the new Chinese made cars that will soon be imported to the USA should come with this oil, & it should be a lifetime fill. No oil fill cap, & no drain plug.
The NHRA drag racing teams use 5W and even 2W for qualifying races in Pro Stock class. I know this 2 ways. I attend races frequently (going to Columbus Ohio this May) and look under Racing Oils on Redlines website.
0W5? You might as well take a *** in the valve cover. Same viscosity.
I like the name of the oil though. NEO.
Look for their new lubricating grease called "Agent Smith".
