Prior to researching in the automotive field, I was a nail technician(the salon lol). I researched on what was the best products and really found only one brand did things right, out of hundreds. Which is kinda scary if you think about it.
So I was thinking if that was the same situation with car oil. I understand that there are testing that approves oils like ILSAC seal or the starburst seal on these oils. But is there one particular brand that really sets itself apart? My guess would be Mobil 1 since they have a good research facility.
What brand oil do you recommend and why?
