You guys and gals don't give any real reasons why NOT to use this quality oil.
Comparing synthetic oil to used underwear or condoms makes for funny and entertaining reading; but has no basis in reality of the subject matter.
I forgot to say that the oil analysis reports we send out on each vehicle recommend much, much longer cycles of oil service. The only reason the city wants the oil changed at these intervals; is the fact they want every vehicle saftey inspected at 3000 intervals. While in the shop; do a service, whether the car needs it or not. Plain and simple.
At $5.00 a quart (U.S.) I like the idea of "free".
