Jason Roary uses Lucas Heavy Duty Oil Stabilizer in 2001 Mercedes SLK 320

I've used your power steering treatment before, and it worked great. My Mercedes started having a nasty valve clatter at start-up (even in warm temperatures) that lasted a good three minutes before it went away. I figured that I had a good experience with your product before, so I'd try the Oil stabilizer- I drained 2 quarts of oil (car holds 8.5 quarts) and added 2 quarts of Lucas Oil Stabilizer. Within 2 weeks and 350 miles, the valve clatter is completely gone. Even at temperatures down to 18 degrees. I couldn't be happier with this product. From now on, I'll be using 20% Lucas with all my oil changes. THANKS!
