Where is Fenner on this one?
Rural King Ocala was stocked up with Areo Shell 100
My question is I have heard in the distant past that Aircraft engines not used daily or very frequently should be sure the oil has some Lycoming cam additive spec?
Let’s hear from the experts
From the Amalie Oil thread that I linked to.
I have broken in at least 100 engines with ashless dispersant oil, no issues, the Amalie oil is fine, has same properties as aeroshell.
There are multiple types of Aeroshell, straight and multi weight. In SAE 50 straight 50 weight there are 3:
Aeroshell 100 - Straight Mineral oil, no ashless dispersants. For Engine break in
Aeroshell W100 - Straight Mineral oil with ashless dispersants. Standard Use
Aeroshell W100 Plus - Straight Mineral oil with ashless dispersants plus the Lycoming Cam additive. Standard Use
I have no idea why Shell uses the "100" in the name when it is a 50 weight oil.
Amalie is equivalent to the W100.
Phillips Victory is equivalent to the W100 Plus
I do not know how similar Camguard is to the Lycoming cam additive. The Lycoming additive is specified to stick to the cam and tappet bodies to prevent corrosion during storage. Camguard also claims corrosion protection.
I find the Philips Victory to be the best value since it includes the Lycoming cam additive. The Lycoming Cam additive sells for $68 for 6 ounces on Aircraft Spruce and you need 2 for a 12 qt case ($136 plus tax & shipping). So even if they gave a case of Amalie away with every 2 bottles of the additive, an $87 case of Philips Victory is way cheaper.

Nothing against Amalie, but note my other thread, looks like I best be running some cam additives! If Amalie included a cam additive (of any kind) and the price was right, I'd have no issue running it.
