I consider Castrol four stroke oil to be upper end.  I've never run
anything else in anything with tires and a motor.  When their TCW-3
came out, I bought a gallon.  I'm still finishing off the last of the
Quicksilver before switching over.

 OK without getting into a full blown TCW3 debate, is your personal opinion
 that Castrol would be considered an "upper end" oil or a "lower end".  I
 don't want to debate whether the "upper end" is actually better than the
 "lower end", because I know that is debatable.  I just want to know if
 Castrol TCW3 has a good reputation for marketing a quality product.
 This is the Castrol Super Outboard oil, NMMA TC-W3 certified.
 I've burned a gallon or so.  The only distinctive thing about it is that the
 smell of the oil itself is distinctly different than the OEM bulk John/Ev
 and Quicksilver I've been using this season.  I've never noticed this
 distinctive a smell for TCW3.  Haven't noticed any difference in smoke or
 performance.
 By the way, I am not of the school to save $5 on a gallon of oil just to
 save the money.  Given my use of approximately 200 gallons of pre-mix a
 year, the savings just doesn't amount to much, so I just don't worry about
 it..  I'd save a LOT more money by price shopping for the gasoline!  (which
 I don't really do - I go to the station that's most convenient and provides
 easy access for the car and trailer.)
 The reason I'm trying the Castrol is that it is quite a bit more convenient
 to me to buy it at the local hardware store than drive across town to the
 Merc or Johnson   dealer to buy the OEM oil in bulk.  Price for the Castrol
 ($11 /gal)  is about half way between the cheapest ($5-7/gal for off name,
 el-cheapo) to the most expensive ($15 - $20 for OEM or Penn. full synth).
 Like I said, price is NOT the factor, but convenience is.  Store is right on
 my route home and saves a good 30-40 min round trip to the boat store.
