Guys , i have a 2007 silverado with the 5.3 and its coming up for an oci. i was wondering what oil you guys like with this engine if anyone has experience with them. It will be used for towing a boat occasionally with short trips of less than 10 miles and plenty of stop and go. I am thinking on pp with the AC Delco oil filter.It has 16,000 miles on it...THANKS BTW...I wont be going by the OLM as I am too OCD to be messing with all that...Ill prob be going about 5k oci and am set on synthetics for now
