Does anyone know much about this oil?
http://images.peakauto.com/PEAK_5W40_CJ4_spec_sheet_no%20back_lores.pdf

Who actually makes this oil? Valvoline, maybe?

Thanks!

Who is qualified to determine the future performance of an oil based on a Blackstone type VOA?

I'm just asking "in general terms" is this oil a decent oil to use. Is it comparable to Valvoline, Rotella or DELO.

Yes it is. Unless you have testing facilities and methods that surpass the API equipment and testing methods it is as simple as that.
A CJ4 oil is just as good as any other CJ4 oil unless documented tests results prove otherwise comparing two oils under the same exact testing methods. Any claim otherwise means nothng more the old snake oil.

You asked abut Peak oil, a certified CJ4 oil, there is no proving another CJ4 oil twice at its cost is any better, other then fancy marketing.

Yes, it is comparable. Warren oil bottles for many companies/brands.

Look, I'm just poking fun. If it were that simple we wouldn't have BITOG. grin

My truck's book says the oil must be fully synthetic, 5W40, meet FCA MS-10902 and CJ-4 or ACEA E9/E7 or ACEA A3/B4.

So, not just ANY CJ-4 oil will suffice.

Generally speaking, in a vanilla application, yes. But, what builder approvals or ACEA specifications does it meet? An E7, E9 CJ-4 lube tends to have a starting TBN higher by 30 or 40%.
