    I own a 2018 Elantra Sport 1.6T with FBO mods. I drive it casually during the week, but on weekends, I take it up into the mountains. I use Amsoil 5W-30 and change it every 5,000 miles.

    Great information. Naturally aspirated V8 engines for the win. I’ve used majority of these oils at various points in time. Now I’m exclusively using valvoline restore and protect.

    Great video and all true! I’ve been using AMSOIL for 28 years and some added info along with multiple tests that show AMSOIL performs the best is, AMSOIL is a family owned company and they have extremely high standards, they don’t compete on price like the others on most auto parts store shelves, they’ve been making synthetic oil longer than anyone in the USA and they are driven to make the best products and continually test them to make sure they stay that way.
