Mobil 1 is great stuff. Switched at 89K and no problems since then (144K now). No drips, no leaks, no burning. My car was well cared for though, with no pre-existing leaks, so YMMV. I love the fact that Mobil 1 can handle much higher temps without breaking down. I'm also very impressed by it's cold temp viscosity, since these New England winters can wreak havoc on engines and make regular oil as thick as molasses.



Try this at home: buy a qt. of Mobil 1 and a qt. of regular oil. Put them both in your freezer for a few hours. Take them out, open them up and pour a little amount of each one into a small container (so it isn't wasted). The difference in the way each oil flows is amazing. That's why Mobil 1 is in my cars!
