Important oil information for anyone.

[TurboWS6]

Just putting this out there.

Backround a few years back the gov. made the oil manufactures cut down on the concentration of zinc in the oils today.

End result, over the past few years several things have started coming more frequent

There have been a rash of turbo failures across the board.
If you run a old school motor that's flat tappet you are now on borrowed time.

In the LS community:

LS7's are dropping exhaust valves due to valve guide failures.
Cam bearing failures have increased.
Lifter failures failures have increased.
Cam failures are up due to the above.
ect.

Please read below, it was written for the 4G63 crowd but most of the information is relevant to everyone on the site. It also lists comparisons of several different oils.

What kind of failures do you guys know of that can be linked to oil among the other brands? What oil do you run and how has it worked for you.
