edit- Jim, the analysis guys say it's 'pretty good' but certainly not as good as Amsoil.

Amsoil is always best.

I've been using VR-1 because it's got some zinc and it's easy to come by.  I was relieved to find that they went back to a proper lid when I bought the last jug.  Those over-engineered two-part pour-spout lids were stoopid.

You think those are stupid, try the new style gas cans, talk about a ergonomic F-up.

This one has high “Bam!” and “Pow!”, as well as “Zink!” content…

I have a newly built high performance M10 engine and this is what the engine builder used / recommends, high zinc ,

Been driving 02s for many years using regular oil and camshafts have not been an issue, ever.

One of life's little mysteries--M30 engines--basically an M10 with two more cylinders--historically have experienced cam wear, which, as tech71 says, has never been a problem with M10s.  The cams on my two showed no wear after 227k and 204k miles with normal 4000 mile oil changes, all using conventional oil.

Well, the M30 has half again as many bearings- does it use the same pump as the M10?

You'd think it'd want more volume, especially at idle...

The ZDDP didn't go away until the mid- 2000's- so engines that were well broken- in 

before then didn't have many problems.

More so if your running the stock cam and springs.

It's still around on SAE 40 and thicker stuff.  Went away in lighter stuff because of new cars with catalytic converters.  Most newer cars use SAE 30 and lighter, except for people that are under the thicker is better impression.   The Amsoil Z-Rod stuff can be had in SAE30 High Zinc because it's for Roddin.

After a 10w-30 break in, I run M1 15w-50, my go-to for the older cars (TR6, old Rovers), however I may be converting the entire fleet to Redline 10w-50 for simplicity and volume pricing....three of the fleet take a combined ~31qts of oil😀  High, but not excessive P/Zn and Mo, high flash point, etc.
