Auto- 2004 Honda CR-V
Miles- Engine= 40,000 mi, Oil= 20,000 mi
Oil- M1 0W-20. Added roughly 2/3 qt per filter change.
Oil filter- "oversized" PL14459 changed 3X (7k,6k,7k) BP media was used for full 20k m
Air filter- replaced OEM filter at 20,000 mi on engine with Napa Gold Prem.
Blackstone's comments:
"All wear looks good in the latest sample from your Honda, especially after 20,000 miles on the oil. Potassium and sodium were the only unusual findings. Potassium is the biggest concern since it often shows anti-freeze contamination. Silicon may show dirt getting past the air filter, or it could be from sealers if this engine has recently been opened for service. This could also be the source of the potassium as well. The TBN was mildly low at 1.7, so the oil doesn't have a lot of active additive left. Suggest resampling in 10,000 miles to monitor potassium."
Car was driven moderately, mostly highway by the wife. Was only driven spirited on the weekends by me. I'm not sure what to make of the high Silicon and Potassium as all appears normal upon a "general" inspection. After taking my sample, Oil (color appeared normal) and FF filter was changed, air filter and BP element was not changed. I will do a UOA as recommend in 10,000 miles.
