Camguard at 10 hours?

[A64Pilot]

It’s possible the carbon is coming off of the bottom of the pistons, it’s not uncommon for a bunch of it to flake off every once in a while and or I’ve seen it when people put MMO in the oil too, presumably the MMO breaks it loose.

‘I know of nothing bad that carbon is a part of or any bad operating technique that generates excess carbon, of course excess rich and or too cool etc can and excess oil consumption, but that carbon doesn’t often find its way into the oil as much as it goes out the exhaust. Yes of course some makes it past the rings, but not usually in bits.

Well - basically, I'm running XC, and I'm just trying to figure out whether I can/should dump a few ounces of CamGuard in there for corrosion protection.  I know that I could drain the oil and pickle it, but we're only talking about a few weeks.  If the juice isn't worth the squeeze, that's a completely fine answer - I really just wanted to know whether CamGuard was going to have a harmful effect on a cylinder with about 15 hours on it.

The linked oil is exactly for what you want, it’s even an excellent break-in oil. Simply drain and refill before it goes to the shop, don’t even bother with the filter, not much could be easier. Then on picking up the airplane just fly with that oil until break in is complete. Then change to AD oil and Camguard if that’s what you want to.

Not to disparage your Avionics shop but things taking longer than quoted isn’t uncommon. Putting the linked oil in isn’t pickling an engine, not even close. Pickling is probably the most conservative thing but isn’t likely necessary here. I’d hope for a couple of weeks, but don’t be surprised if it turns into a couple of months

Understood. Thanks A64, this is a good suggestion. I had just changed the oil with XC a couple of hours before the plane went into the shop, and ultimately I went ahead and added some CamGuard right before I dropped it off. I’ll keep this in mind for next time.

Good. So CamGuard by itself is purely an anti-corrosive with no anti-scuff properties?

Correct. Camguard reduces corrosion and also helps prevent formation of deposits to keep the engine clean inside.

Yet the Camguard website uses the term anti wear and anti scuff:

“CamGuard Aviation contains powerful multi-metal corrosion inhibitors that prevent rust and corrosion in infrequently used engines.

CamGuard Aviation contains advanced anti-wear additives to dramatically reduce the wear of cams, lifters, cylinders, rings, gears and valve guides.

CamGuard Aviation provides excellent anti wear (anti-scuff) protection, during “dry” starts after periods of prolonged inactivity, by maintaining a residual active film on critical parts.

CamGuard Aviation utilizes unique ashless deposit control additives that prevent the formation of deposits throughout the engine. In older engines the lack of new deposit formation allows component motions to free up deposit laden sticky parts.

CamGuard Aviation contains seal conditioners that nullify the effects of heat and time to keep seals supple, flexible, and performing like new.

CamGuard Aviation is compatible with all aviation oils including mineral based, and semi-synthetic types.”

That’s pretty frustrating tbh. Seems there’s generally a lot of misunderstanding about what this product does. 

I started using CamGuard largely because of broadly positive reviews here on MS (as well as industry sources like Aviation Consumer and Mike Busch), and primarily because I was concerned about corrosion on an engine that flies about once a week. 

I’ve been pleasantly surprised at improved compression numbers and lower oil consumption.

Exactly.  Again I’m no expert but without a MIL Spec of some sort and a test program to back it up, I don’t know how anyone knows what’s in it.  It may be a fine product but how can you know how different it is relative to other products like Phillips Victory that at least have a spec associated with them.  The CG web site says it had 11 additives.  I don’t see anything to base a decision on other than marketing, slick and glossy brochures and tribal knowledge and experience.  I often wonder if a single weight oil is the best you can do.  Isn’t it sticky as heck when it’s cold.  BTW I may put camguard in my boat now just for the heck of it.  I’ll feel better.
