I have two motors that I need oil recommendations on: 1) Stock longblock K20A (2.0L, 86x86mm), ~230WHP, running it to 8.5K daily. Motor has 55K miles on it, and running an open element air filter. 2) Built K24 block (Supertech 12.5:1 4032 alloy pistons), ported K20A head, big valves, big cams. Also revving to 8.5K, more of a weekend motor. 315WHP. I'm currently using Pennzoil platinum (or Ultra if I can get my hands on it), 5W30. OEM Honda S2000 filter. Can I use this in both motors without worrying too much?
