its mineral oil.  It was originally called lenkite. Save your money. Use MMO to free up sticking valves, or better, ream the guides and clean them properly.

I'm not sure what Avblend is exactly but it's more than just mineral oil, you can smell the difference.

Aviation Consumer really liked the stuff before Camguard came out, after that it kind of got lost in the noise of everyone talking about Camguard.

The historical "data" (stories, possibly apocryphal) suggest that it helps prevent valve sticking.  It also prevents corrosion (rust) as well as Camguard in the Aviation Consumer tests.

Those are the reasons Ronnie probably recommended it.

Avblend smells like hard core alcohol. Definitely not just mineral oil.   Basically, I think the main thing is that it really helps keep containments suspended in the oil so sludge will not develop.  It also soaks into metal parts.   I've had several A&ps tell me they torn down 3000 hour plus engines that had been running avblend and they literally looked new inside.

I don't think there is any evidence that any additive "soaks into metal parts". A friend of mine tore down his 1900 SMOH factory engine and everything measured within new limits too.

according to this, it's >99% mineral oil.  http://www.zmax.com/documents/msds_105_avblend.pdf

There's also no evidence that any additive "prevents rust and corrosion".

To everyone but you, the aviation consumer articles make a pretty clear case Camguard slows corrosion.

It does not "prevent" it.

A top quality aviation oil such as Aeroshell will do better than any additive.

Frankly, PTK, you're full of it, and willfully ignorant. Aeroshell W100 can form rust on the cylinder walls in as little as 3 days.

No it can't, its the water that causes the rust to form, W100 cannot form rust.

Frankly, Byron, what you put in your engine is your decision. Just be careful you don't spill any of that kool-aid you're drinking in your engine! It will form rust. 

I refuse to contaminate my engine with additives. I choose instead to fly my airplane at least once a week, use the best oil money can buy, i.e. Aeroshell 15W50, and change it q ~35 hours as prescribed.

You see Byron? It's easy!

[jetdriven]

That's your choice. But an anti-corrosion additive extends the interval in which rust forms on steel parts inside the engine. Which has been shown to be extended by Camguard in numerous tests. Sorry, but your ignorance is no match for fact.

Such as found in a top aviation oil.

You're right. The oil company puts in lots of additives to extend life, resist corrosion and suspend particulate so it travels to the filter. Some people feel the need for more additives. How many additives are in your preferred toothpaste, Mr. Dentist, sir? Some to foam up nicely, some flavoring for fresh breath, some use additives so that it "feels" like it's cleaning, more additives for stain removal and polishing, the list goes on . . . Motor oil from the big companies, and the small, is no different.

Sure, it's just Triphenyl Phosphate, instead of a dozen or so chemicals, and only 1/25th as much. But if that satisfies you, go ahead.

Hoping to keep thread on point and not turn into an oil debate.  Saw this and thought it to be relevant to this thread.
