Here's the latest UOA for my 2007 Nissan Murano. This run was on Pennzoil Platinum w/ Pure Plus Technology. The prior UOA's were PP 5w30. Since the prior oil change (5/17/14) I traveled up and down the East Coast on I-95 visiting family in NJ, VA, and Miami FL.The first trip was in June to NJ and return to SC. Next was up to VA and back to SC. The last trip was in August to Miami, FL and return to SC. The trip to VA and back was done in 1 day. When I leave my residence I'm on an interstate within 10 minutes. On July 4th I traveled to Emporia VA on all interstates. My earlier trip to NJ was to pickup my grandson for a 2 week visit to SC. At the end of his visit I made arrangements with my son to meet in Emporia, VA to pickup his son. We met, had lunch, refueled and I was back on I-95 southbound to home. I drove non-stop with at speeds from 70- 75MPH till I arrived home. So my Murano was very busy this summer. As far as the increase in silicon I can attribute it to the new Pure One air filter I installed at this oil change. This is the first time I used a Pure Oil air filter. I replaced the Pure One air filter with an Amsoil air filter on this oil change. I used a Mobil1 Extended Performance oil filter on this run. Thanks for looking.
