So I changed my oil for the first time yesterday. Put in Castrol Edge w/ Titanium 5w20 and Fram Ultra filter. Sounds like less piston slap when I turned it on this morning, could be in my head though. Anyway, from reading some reviews on here lots of you seem to like Pennzoil Platinum, and UOA show that so do the Honda engines. Between Platinum and Ultra which would you recommend for my next oil change down the road? Price doesn't matter. Which one would give me a quieter running engine also? Ive seen a couple UOA of the platinum, but not much on the ultra. Also should I stick with the Fram Ultra filter or would something be better? Is K&N any better than the fram ultra? what is the filtration % on those? thanks!
