Gonna be some spendy oil, they're still working on making lab test quantities of graphene with any type of consistency and quality control.

nha they found a way to make graphene ,it is like a jet engine thing but the end output is squeezed and it deposit it in film witch can then be used.

I can understand the principle of a graphene coating. I can't see how it could be used as an ingredient in a finished motor oil, without it being pulverized into amorphous graphite, which, as others have already indicated, we do not want in our motor oil.

That sounds like a great way to treat a surface but not practical for large scale production of bulk product. Still a lot more expensive than other products that are well suited for use as an additive.

ya graphene is expensive ,but its properties are so uber that I highly doubt it will be ignored!

Which of its properties do you think are relevant to motor oil?

sidenote:any have ever had rotary engine?(aka wankel in the mazda or other car brand,wouldnt a graphene film be perfect for those troublesome leak prone engine?

I cannot list all the properties of graphene,the list is too long but it is very different from graphite (wich had troublesome problem like corrosion

Actually yes I did, a very rusty 1984 model that burned a lot of oil. It was fun to drive though. They didn't "leak" oil as such, it was apex seal wear that was the problem. Oil consumption was a secondary problem, the primary issue was loss of compression.

If graphene is added to motor oil would it bond to surfaces?

From what I've read with google searches no it doesn't. It's like Teflon from what I understand and doesn't work like mos2 in relation to "plating" moving parts

Why not MoS2? It bonds to metal. It's available. I've never owned a Wankel engine, but problems with the apex seals are well known.

Well, actually I would if it had new apex and side seals, and I knew the compression was good.

Then again that particular car is now incorporated into a bunch of green bean cans, and even possibly my current cars smile
