Picked up the truck in November and did the first oil change through the dealer. Second oil change I did myself and discovered I had used 3/4 of a quart over 5500 miles with the factory gm oil. I refilled with Mobil 1 EP 0w-20 and a Mobil one EP filter. I’m pretty sure I’m over analyzing this but is this a good oil for towing? Oil consumption is about 1/4 quart at 3k miles so far. 90% of my miles are gonna be highway miles BUT I have a travel trailer I use for work that weighs 6500 ish loaded out and some jobs can be 900 miles or more from home. My concern is how this oil would handle towing like this. Are there better options? I might make 1-2 trips like this in a year and myself and the wife take trips with the camper as well. I’m new to the site and really just would like some opinions. I run valvoline advanced synthetic in my wife and daughters Camaros ( 2019 with v6 and 2020 with 2.0 turbo) and have no rock solid preferences for brand but have ran a good bit of valvoline and castroil in the past. I was told by my service guy that he didn’t recommend the factory oil for past 5k miles. He owns one and says it’s purely personal preference but he doesn’t take his past 5k miles. Honestly I don’t mind paying a little extra for a quality oil that will give good protection for my engine and I’d really like an oil I can sleep well with going by the oil life monitor. The oils I’m considering are the mobile 1 EP, valvoline advanced synthetic, castroil edge, or amsoil ss. I run all amsoil in my atv and love it but it seems like a waste considering I’ll only run it for 6-8k miles. I realize the EP is an extended interval oil as well but it’s half the price of the amsoil ss.
