First, a thank you to all who contributed to making my Ford Contour last to 156K before I traded it in.
Now I've got a 2004 Ford Taurus, purchased in February at 20K miles (Certified pre-owned, 6 years/75K warranty). I'm ready for my first oil change. Having a debate with the dealer mechanic. I was going to have them put in Slick 50, which my dad insists is a great preventative: an engine lubricated with Slick 50 every 50,000 miles from the very beginning won't experience engine part break-down, he says.
The dealer argues. Oil today (I'll be using 5-20) is so good, you don't need Slick 50 and will NOT suffer any engine part damage until... well, don't start using it until 80K, after your warranty expires, he says. My paranoid internal reaction: "You want me to neglect the slick 50 for the first 80K so that the second the warranty expires, I'll start having unceasing engine problems."
Thoughts? I used Slick 50 in the contour from the get-go (bought it 3 years old with 30K on it).
