BITOG Gurus: Here is the UOA for my 2007 Nissan Quest. The vehicle ran for 365 days with Amsoil Signature Series 5W-30 and the Amsoil EA15K filter for the vehicle. The van is my wife's vehicle. She was unemployed for the first 5 months of the year so it didn't get many miles. She got a job in June and commutes 9 miles each way - 18 total daily commuting miles - plus a little bit on the weekends. The silicon may be due to the K&N air filter. I have a paper unit I will be putting in tonight. What really gets me is the amount of lead. Any insight from you all? How do I correct? Should I be worried? What could happen? Also, they are suggesting a run of only 6,000 miles to see if there is any improvement with the lead. I put Amsoil SS 5W-30 back in when I changed the oil. The SS seems a little expensive for only 6K. PP might be a better choice?? I ran PP from 2007 to 2013 when I put in the Amsoil SS. I thought the SS would be a better choice for longer drain interval. Can PP go 12 months? With the amount the vehicle is driven daily it will likely be the better part of a year before it gets to 6K for me to change. Even at two oil changes yearly, is PP a better choice then the Amsoil SS? Shouldn't the TBN be higher then 1.9 after only approximately 8,300 miles? The oil is supposedly good for 25K or 1 year.....I went the 1 year route. Thanks in advance for your input, information and ideas. edit: The vehicle currently has 60,xxx on it.
