Who still recommends 10W30 5w30 is much newer chemistry, 0w30 and 0w20 are even newer and the direction that things are moving in.
I would prefer to have a longer filter for the sole reason of when the weather is cold (-20F) and the oil is thick I would rather have more filter area for the cold thicker oil to pass, rather then have it force open the bypass valve.
