Does anyone have a good oil recommendation for a vehicle that has some slow leaks?
I have been running Supertech (Warren) high mileage synthetic 5w-20.
Recently I switched to Mobil 1 0w-40 because I felt like it. My truck has a few slow oil seeps that I do not want to repair right now ($$$). Should I keep running the M1 or switch to a 5w-30 HM syn? Recommendations? Thanks!
