Looking for a recommendation for which synthetic to use for my new truck, a 2010 GMC Sierra with the 5.3L Aluminum Block Flex-Fuel engine (and 4WD). I'm good with store-bought or online-bought oil. Despite being a flex fuel engine, I don't plan on running the E85 due to cost and limited availability. I haven't actually taken delivery on it yet, but once I do I plan on changing the oil over to the synthetic after the engine's broken in at 500-1000 miles. The manual says to use a SAE 5W-30 oil that meets the GM6094M standard. I live in North Texas, so winters aren't terribly cold and summers are very hot.
My driving style is what I'd call moderate (not slow and lazy, but also not fast and hectic). My normal commute is right at 10 miles one way, and my driving mix is about 80-90% on typical surface streets in moderate traffic, the rest being highway driving. Only occasionally do I drive off-road or on unpaved dirt or gravel roads (maybe once a month at most). I'll only put about 1000 miles a month on the truck, so I don't necessarily need an extended oil change interval, but am also fine with one if that's recommended. I only occasionally tow (maybe 1-2 times a year, don't come anywhere close to the max tow ratings) and haul heavy loads (maybe 8-10 times a year, at most 1000 lbs, well within the payload rating) so this is primarily just my all-around vehicle, not a true work truck.
Thanks for the help!
