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... -Dan Masys N104LD 620 hrs TTSN ________________________________ Message 2 _____________________________________ Time: 11:05:46 AM PST US From: "Pascal" Subject: Re: RV10-List: Oil choice 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.

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.
