Roller rocker camshaft, funky contact strip

Hi SonyAD, what is the particle size in use for the MoS2 and BN??
Thanks Rob S

Do you have a Used Oil Analysis you can post?

Some aftermarket oil additives can promote wear due to presence of chlorine https://www.amsoil.com/techser...ments.pdf?zo=1181889 .

The newer API oils have lower zinc and phosphorus levels causing excessive wear in flat tappet camshaft engines https://www.amsoil.com/techser...appet.pdf?zo=1181889 .

Hi.

Don't know for the MoS2 but particle size for the boron nitride additive (same manufacturer) is, per their data sheet, less than 0.2 μm or 0.5 μm (not sure which is outdated).

Here are a couple more recent pictures of the thrust side of the cam:



Something clearly went on.

Nope. I'm just an end user of the product.

Don't know of any outfit like Blackstone around here.

And I'm not sure they'd be able to tell much else besides the spike in Boron anyway.

Hey I haven't change the oil, so at what time period it require to change monthly or yearly.

I'm not sure I get your question.

They say to use the additive at least 5000 Km before an oil change.

But I heard that the additive can be used at least 6000km before an oil change.

Yes agreed with you!! It dosent require to change monthly or yearly.It depends on how much you drive it!! Even I heard it can be used at least 6000km.

ya i too agree with your point definitely required to change

there is no need of replacing before 5000km. It work well upto 5000km. it depends on the way we drive.
