Mobil 1 comes in 15w/50 ................ run it.
I put Mobil 1 in at 8000 miles, now have about 14000 miles. Its due for a
change.
If you're going from regular multi vis oil, run a quart of Marvel Mystery
oil for about 300 miles before you change to Mobil 1.
If you don't clean the varnish and sludge out the Mobil 1 will. Its
better to have the sludge in your oil recycling barrel than in your
engine.
