Friction Modifiers?? What are they?

[Ramblin Fever]

and can you give me a list of oils which have them?

I'm not exactly up to par on the definitions of the different oils, and this description comes up a lot as being a good thing for OHC engines??

 

[Ramblin Fever]

Bump. This forum moves FAST!

Did you look at the Cliff Notes here:

[Ramblin Fever]

So, basically ALL oils contain friction modifiers?

I didn't get much off that page in regards to which brand has what, or if they all have those additives.

I think you squelched your own thread by asking for a list of oils with friction modifiers!

 

[MolaKule]

See the threads in Question of the Day:

Any oil that says energy conserving has some type of friction modifier.

Pablo - Gotcha, it makes sense now.

MolaKule - THANK YOU! "Any oil that says energy conserving" tells me what I need - THANK YOU.

Graphite is also a friction modifier.

It's not that simple. Even if it doesn't say "Energy Conserving", it probably still contains friction modifiers. Most modern oils contain friction modifiers.

Shoot, for that matter, oil is a friction modifier . . .

 

[y_p_w]

I think the point about the "Energy Conserving" label virtually guaranteeing that the oil has friction modifiers is as follows.

It's a reasonably high standard. In order to meet it, the oil is going have to be rather thin AND will need very low friction to outdo the synthetic 5W-30 reference oil. A thicker oil could still contain friction modifiers, but wouldn't meet EC because of higher internal drag.
