So after decades of blissfully thinking I was doing the right thing for my

aircraft engines by feeding them Aeroshell 15W50, it now is being called

evil stuff by knowledgeable folks like Mike Busch.  Is there general

consensus that Phillips 15W50 is better as a multiviscosity oil for our

IO-540's?  



And if using that does it have to be supplemented by Camguard to add back

the Lycoming 'snake oil' additive to protect the parts that are only splash

lubricated?



Not trying to set off oilfield flame wars but have the feeling that somehow

I missed something...

15w-50 is for radial, get the XC 20w-50. I used it for well over 100 hours- 

straight, than I used it adding camguard, now I use Aeroshell with camguard.



Ask yourself, where are you located (if 100 miles from ocean and in warmer 

climates, like myself in So California, I could use the Aerosheel w100 year 

round, I'll switch to phillips for the winter anyway, in case I go up to the 

mountains 20 minutes away.

If you fly often, and/or not near ocean or corrosion prone areas, skip the 

camguard. basically everything Mike comments on on his webinar.

The problem with AS 15-50 is that it is 50% synthetic oil which does not keep solids suspended.



It does contain the Lycoming addidtive.



You do NOT need the Lycoming additive. It is for the "76" series engines like the O-320-H2AD that had very different cam and lifters than what your IO-540 has. The Lycoming additive is a version of tricresyl Phospate, or TCP, and is an extreme pressure lubricant. Later replaced by close cousin TPP.

 

Phillips does not have that additive, and I don't think Camguard does either. Camguard is primarily an anti-corrosive, which is helpful in preventing pitting on the cam.



The Phillips/Camguard combo gives best anti-corrosion protection. The Phillips is all mineral based, no synthetics.

Ditto on this. I use Phillips with Camguard except during the first 50-100 hours on a new engine, where I leave out the Camguard.
