"Oil" threads are like beating a dead horse
The reason certain topics are like that is interestingly multifaceted.
In most cases, it's mainly a teaming up of MARKETING FUD and supremely illogical people.
However, also in most cases, it's in a product that really makes absolutely no difference.
So, when you add up these three things:
1. MARKETING FUD
2. Emotional people
3. Commodity
You get the "what oil", "what gasoline", "what coolant", "what brakes", "what tires", "what brake fluid", etc, threads (don't even get me started on the myriad miracles in a can).
