The Mobil 1, 15w-50 is one of the better oil choices out there. While it is
somewhat more expensive the extended life and wear protection is more than
worth the difference, especially if you use good filters (oil and air) to
keep it clean. If you go to a non-synthetic you should use a 20w-50 for most
weather conditions. The Mobil 1 15w-50 is a high ZDDP oil for older flat
tappet engines (if you believe in that need). For normal use oil testing has
shown that it is good for 7,500 mile drain intervals.

My 85 Westy came with Mobil 1 in it.  Should I stay with Mobil 1?  is this
overkill?  Are there better alternatives?
