In my GXL - I had put...
summer: 10w50
winter: 20w50
This is all Gastrol GTX, btw.
I think. I don't know. It's been about a month since she hasn't ran. So, I could be a bit off. I do knwo that summer is a lighter, and winter is heavier.
As far as the filter goes, i'm not sure of the brand name, but we use the one that looks orange or white.

I thought gas made the car run. Anyway, I use Castrol 20W50 in mine, don't use any specific filter, has Fram on it right now.

Because my theory anymore is, the engine has good oil pressure, good 'nuff.

I had thought you shouldn't be using Synthetic in rotaries... or so what I've been told.

been using Castrol GTX until now ... but i'm switching to synthetic now ... exclusively! just can't decide between AMSOIL and Royal Purple 
it's funny i should find this thread because i actually logged in to start a thread to do a poll on the syntethetic users out there - i know we're few.

Well the low oil light came on yesterday so I had to break down and buy oil for the car. 
Now here's the kicker... the oil I did buy was cheapo 99 cent per quart stuff. Quaker State was cheaper than that! However, I would strongly recommend to everyone, no matter what kind of engine they are using, NOT to use "Pennsylvania" oil (Quaker State, Pennzoil) because it is known to sludge up like you would not believe. It is complete garbage. I have had engines that lived their whole lives on Quaker State and you pull the valve cover off and it looked like someone used the valve cover to make a sand castle out of sludge. Literally had to spoon the stuff out to even see the cylinder head, and the rockers were just barely visible. AWFUL.
The Pennzoil 2-cycle oil is great stuff, though. I'm only talking about motor oil.

Where do you guys get the royal purple racing oil from, I haven't seen it at any of the stores that I have checked. Any advice on where to get it.

I took the oil pan off my '74-ish REPU engine and the bottom had a very very thin sludge of blackishness. I think it was caused by Castrol 10w30 (ash content, anyone?).
Is there an oil out there that is cleaner? I think it was stated here and there that Valvoline is better than Castrol in 10w30 and 20w50 weights. I only remember Valvoline because of the word 'valve' in it lol.
