I called Shell Motor Oil today about their Rotala engine oil. As of now. That oil still contains 1200 PPM of ZDDP. I was told that some new Federal government standards are expected in 2016. I got the same story from Northland Oil. I have also found out that some oils now that are classified as SL. Don't contain 1200 PPM of ZDDP anymore. So we're good till 2016 in regards to ZDDP.Bob Dunahugh
