you can safely run 20 or for more protection to the parts, 30 in the TL, regardless of gen2 year
CAFE fuel standards in use for a time caused acura to use the 20 for testing purposes, but for engine protection 30 is better
your owner book list ALL the approved weights for what ambient temp conditions

thats my current fill, castrol edge 5w-30 and bosch distance plus fliter. i plan on running it to 10k+ miles hopefully, with the extended capacity filter. we will see how castrol holds up, i was hesitant to put it in my car (i dont buy their marketing bs 8x better wear protection garbage), but so far very good results. they just released a new formula that has titanium in it, dont have it yet. castrol edge 5w-30 is a really thin 5w-30, almost a 5w-20 and shears down well into a 5w-20 after a few thousand miles, but that wont hurt our engines at all. Iv seen very good results with mobil1 EP products, especially cleaning abilities, so i am waiting to see how well castrol edge holds up.
