I am not up on the current HDEOs. Have a 2005 Dodge 3500 dually 6 speed with 95k miles. Truck is driven about 4,000-5,000 miles a year, some towing, but nothing super heavy. Operated in Northern California, coldest temps is sees is about 32f, hottest 105f. I have been using Kirkland 15w-40 and changing once a year, but looks like my local Costco doesn't have it anymore. What is a good low cost oil, that meets that will work well, and preferably can be delivered by Amazon. Candidates appear to be Rotella T4, Chevron Delo (which one?), Valvoline Blue, Mobile Delvac 1300 Super.
Thanks
