I do ridesharing. I do about 3,000/ month of mixed driving with average speeds of 21-28 mph depending on the trips I get. I believe that puts this in the category of severe service. My owners manual states that in severe conditions oil should be changed at 3,000 miles using regular API, etc 5w-20 conventional oil.
Lurking on this forum and reading the articles on Blackstone's site my understanding is that as long as the oil is changed at the correct interval based on service type, protection benefits between oils are minimal at best.
I just don't want to change my oil that much especially in the winter. I created a spreadsheet to comparison shop the $/mile for several products, both conventional and synthetic. My research shows me that it appears to be actually somewhat cheaper to use synthetics over the course of the mileage they state. Even Amsoil, with it's tremendous cost difference comes in about equal with just doing SuperTech Conventional with a basic filter.
Therefore, it seems like it is a no-brainer to just buy the synthetic oil and not have to do the changes so that I can drive and make money instead for the same or less cost. But it seems to good to be true. Am I missing something here? Why are there so many people that do not go that route? Are there factors that I am not considering?
