Sorry, but I have to disagree concerning "oil is oil"
Look at it this way-oil has to pass a test to be qualified at TCW3. If we assign a number to
passing the test, lets say 65, then if an oil scores a 66 is is certified as meeting TCW3 requirements.
So a cheap house brand might score a 66, and they are good to go. However, a name brand, like
Merc Quicksilver or Yama lube might score a 95, and they are also certified TCW3.
Which would you rather have in your very expensive motor-the cheap oil that just makes it, or the
more expensive oil that far exceeds the requirements?
I for one have never scrimped on any type of oil for any of my engines.
Reminds me of when I owned a tire shop, and people would come in and ask for the cheapest tire I had.
I would remind them that as they are traveling down the road in 3,000 pounds of vehicle with their family
doing 60 mph, the only thing between them and mother earth is a half inch of rubber and some compressed
air, and then ask them if they still wanted the cheapest I had. Everybody then upgraded to the better quality
tires.
