SuperTech, or Kirkland, or Prime, or Mobil 1300, etc... Any of these in 15W-40 served me well in every engine I put it in.
I'm a strong believer that more frequent oil changes (3k-5k miles depending on engine in question) with cheapest HDEO is still better for the engine than extended OCIs with boutique oils, or standard OCIs with top shelf synthetics.
It’s that exact “belief” that is why there is such a big market for VRP right now. There are a lot of engines out there with carboned up rings and oil consumption by people who religiously stuck with 3k oil changes with cheap oil.
In many cases they do it because they have a friend who has 400,000 miles on his old truck using cheap oil. But they neglect to mention that these 400k trucks have engines that burn a quart every 1000 miles, smoke up the place when started up, are making 10% less horsepower than they made when new, and are getting way less MPG due to loss of compression.
And the practice of running diesel oil in gas engines is something that needs to stop. It’s not the right oil for the application.
