Phat8186,
I have Mobil 1 in my CRX. My Civic beater also has Mobil 1 in it at the moment because it's all I had on the shelf when it's last oil change was due.
Now, my wife's 1996 Civic started to develop that piston slap noise around 80k or so. I initially had good luck with the Valvoline MaxLife using their original formulation. That quieted the noise down for a bit. Then, Valvoline changed their formula to decrease the amount of molybdenum disulfide in the mix...imagine, then noise came back. On the recommendation of a friend who does extensive oil research, I've tried PennZoil High Mileage formula in her car. That did the trick for the first 2500 miles on this change. Now, she's due again pretty soon, but it seems that the adative package is all used up...prolly because I was running MaxLife for so long. In any case, she'll get more of that soon and I should be able to get more than 3 grand out of an oil change again.
As far as tranny fluid, I use RedLine MTL. My Civic is due for a change and I'm prolly going to try the Honda MTF, just because I haven't used it and it's about $3 cheaper a quart. I don't trust the new SL grade oils in a tranny...prolly too slippery for the synchros.
Don't run any slick50 in your oil and especially not your tranny. For the tranny, try MTF or MTL. For motor oil, if you do have piston slap, get something with a good percentage of moly, RedLine, Mobil1, Shaeffers, PennZoil High Mileage...If not, and cost is no object, go with RedLine. If cost is an object, Castrol GTX. Don't waste your money on Syntec.
