What is your favorite engine oil?

[tnowak]

I have been using Exxon Elite 20W50 oil in my Cont. A65 since I got new cylinders a few years ago.
My engine man liked the oil due to the special additives.
I now find that Exxon Elite 20W50 is no longer available, so what is the next best engine oil to put into these engines?

We use PHILLIPS 66 X/C AVIATION OIL 20W50 and then add Camguard. This is simply based upon Gilbert's recommendation from other posts as he is far more knowledgeable about such than I.

Ditto... As an added bonus, the oil pump on my A65 quit having priming problems after I switched from Aeroshell.

I have been using Phillips 66 xc 20W50 with Camguard but recently switched to the Phillips 66 Victory 20W50 which has the Lycoming anti-chafe/wear additive in it. I probably will add Camguard as well with it's anti-corrosion properties. Here is some interesting information on oils and additives from the guy who created Camguard:

Thanks for all your info on oil.
I will see what is easily available here in UK.

Interesting comment. I've used Shell W100 with cam guard forever on all my aircraft, but the O-200 has an issue with 'losing prime' after about 2 weeks of sitting. I've just changed it over to the Shell multigrade but have yet to trial it.

Ditto too, I use Phillips XC 20-50, with cam guard.
