Submitted this oil sample primarily to check for silicon levels. Bought new, K&N filter replaced OE @ ~7K miles. Vehicle now with 86K miles so 79K miles using an oiled filter. Cleaned and carefully reoiled twice. Vehicle burns zero oil between average 5K oil changes, always 0W-20 various brands. Lots of chatter and opprobrium here directed at K&N. For sure one sample proves nothing, maybe my Outlander is an Outlier or perhaps not.
