Camguard

[N29945]

Has anyone had a bad experience with Camguard, I have used it for years in Lycoming engines, I was talking to an acquaintance today, he claims he has a 180HP Comanche, flys it about 10 hours a year, was using Camguard in it and the Camguard apparently gummed up the oil rings and caused it to use oil.
I think I know the answer, just checking with the experts.

Only flying 10 hours/year, what else could it be?

So I hear folks conflating CamGuard with Lycoming anti-wear additive. Like “100Plus Aeroshell already has CamGuard”

What say the experts?

I'm not an expert, but I've read a few things that some have written, like these:

@ 10 hours a year what would one expect to happen. Wonder if the oil was changed only once a year, how was it stored, etc... So many questions, but Camguard being the problem is not one of them and not very likely as many consider it to be a good addition for low use engines to prevent cam/lift corrosion.

My 2 cents, not an A&P, but the statement just doesn't sound right to me.

WOW!! Blame it on something!!!!! MUST be that nasty Camguard stuff. NOT
Maybe if the engine was flown more and oil changed it wouldn't have these problems.
I would think the Camguard would help not hurt an engine. But, I don't use it or any other witches brew except clean, new, aircraft oil. Oh ya and flying.
How about the fact that it is an engine and needs to be ran to keep the corrosion away.
I bought a Chevy 454 out of a wrecking yard to put in my 89 GMC dually one time cause mine literally blew up.
With in 100 miles the cam got ate up because it wasn't run for who knows how long and was more than likely rusted up.
My three cents worth Art

They are quite different. The Lycoming LW-16702 additive has an anti-scuffing agent that serves to reduce wear.

Per Ed Kollin, the developer of Camguard: "Camguard uses 11 high performance additives most of which are multi-functional. They are all commercially available and expensive. It uses multiple ferrous and non ferrous corrosion inhibitors, multiple anti-wear chemistries, a very potent antioxidant/deposit control package."

According to Kollin, "the additives in Camguard SWAMP those in Aeroshell 15W-50 and Exxon Elite so why pay for them." Kollin recommends Phillips 20W-50 with Camguard year round.
