Oil brands is sort of a can of worms, there is a lot of opinions about them. Could still be fun to hear if someone has had bad experience or very good experience with that oil. Or if someone else is using Kendall oils.
When I was truck pulling and working for the team, we tried everything one could think of to squeeze power. Including oils.
The best advice, forget the advertising, send off your oil to a company that does oil sample testing. They can tell you the microscopic parts of metal that are in your oil and how well it’s protecting and lasting.
The filter brand is highly important as well, if you’re running a fram or Walmart type special, forget the oil supplements, upgrade the filters, then the oils.
Oil sampling is cheap and you might be surprised at the results.
