Explanation:

Platinum plugs are meant to be used for like 3% or 4% of your car's
life. They are good for cleaning the carbon out of cylinders.

If the engine is already clean of carbon, then the platinum will cause
pre-detonation.

Platinum is a catalyst. In effect, it accelerates the burning of
hydrocarbons. Carbon deposits on pistons and valves in the cylinder
will be burned off by the platinum on Platinum plugs.

When the engine is clean, the platinum becomes a demon.

I learned this the hard way. Extra platinum leads to piston holes.
