When “High Mileage” oils came out several years ago there were a lot of people that thought it was nothing but a marketing ploy to get more money for the oil we always would have run. Other folks believed that the additives that were included would do bad things to certain engines. This video from Project Farm looks at two different brands of full synthetic oil, in both regular and high mileage versions, to see if they can be determined to be good or bad or not.
Does high mileage oil stop oil leaks? Is it safe to use in your engine? Does it offer better or worse wear protection? Let’s find out by comparing Mobil 1’s full synthetic vs Mobil 1’s “high mileage” full synthetic and SuperTech’s full synthetic vs SuperTech’s “high mileage” full synthetic motor oil. I always purchase all of the products tested, and thank you for supporting the channel!
