What type oil should I use???????????????

Pennzoil Platinum has great oil analysis reviews on BITOG. Also, these claims of 5w-20 not providing sufficient lubrication or protection are bunk. Go over to Bob's the oil guy and read the FAQ. Very informative and dispels many myths.

Slip_Angle, I agree w/u WRT PP; excellent product. But we part ways WRT your comment about "claims of 5W-20 not providing sufficient lubrication or protection are bunk." 5W-20 may provide adequate lubrication in 99.9% of HMC's engines these days, but the vast majority of those engines seldom, if ever, experience high rpm use, and for those that do HMC still recommends 5W-30 (or 5W-40) weight oil. Why do you think that is?

Can you get away with 5W-20 in an EP3 engine? Obviously. You apparently run the stuff, so that's one example. But those of us who opt for 5W-30 weight oil know the additional HT/HS film strength (cSt @ 100c) will never harm a K20A3 engine and it just might be a crucial factor in preventing camshaft galling.
