I'm trying to figure out whether or not any of the following are worth trying:
Slick50, Dura Lube, or Zmax. Apparently the FTC sued the makers of Zmax back in 2001, but recently I saw an endorsement of the product on SpeedTV. Are any of these worth the money, or should I just stick to 10w-30 high mileage oil? My 2003 Protege LX 2.0L has 124K miles.
