Title: Save your money
Review: I got sold the hype to and bought enough RP for 4 oil changes in my 2006 Lincoln Town Car. There was absolutely no difference in gas mileage and what may be perceived as a boost in horsepower is the fact the RP is a racing oil that was never intended for daily use according to my mechanic who works on some of the most exotic cars ever built. So because I was foolish enough to switch from Mobil 1 to RP mu motor now has internal noises and a clatter that was never present before. That has now improved since switching back to Mobil 1 but don't by this garbage unless you're doing some competitive racing. There is may excel but I would never put this in any daily driver. And BTW..., I haven't spoken to a single mechanic who endorses this oil, STAY AWAY FROM IT!
