Camguard

[GraemeSmith]

Anyone running Camguard in the Valvoline VR1 20/50 oil?

As winter makes it harder to fly consistently and maintain oil films - I'd like to improve my chances while sitting. I KNOW it works well in Mineral Oil base stock in Aviation oils. But not sure if the chemistry in the Camguard will conflict with the chemistry in the Valvoline.....

Interesting.. I wasn't aware of this product. I do wonder if it could possibly help with my turbo getting sticky after a few weeks on the ground.

They make Camguard for auto engines and small engines. You might try the Camguard for auto engines.

Hey thanks!

CamGuard Automotive is particularly useful in older engine designs utilizing flat tappet valve trains especially when using modern, mandated lower zinc (phosphorus), oils.

VR1 is already high zinc
'Valvoline VR1 Racing Oil's high zinc formula provides race-level protection for high performance engines on the race track or the highway. Its exclusive chemistry is designed to reduce friction and enhance power.'

Gentlemen,
So as I now understand from reading this thread that Cam Guard is to be used in older flat lifter engines that use a lower zinc formulation. Does this prohibit its use in our AeroVee engines that are using Valvoline VR-1 high zinc oil?
I have, in the past, thought about using Cam Guard because of its high friction surface protection but now I’m rethinking it.
Am I missing anything? Is Cam Guard a high zinc additive that hangs on surfaces long after the engine is shut down?

It's not just about the zinc.

The other principle benefit of CamGuard is helping maintain oil film over an extended period of non-use. That's what I'm really after.

I thought they updated the oil recommendations to not include the VR-1 oil and only list the brad penn

Current manual states:

I believe this was only for the Aerovee Turbo.
