I am using Mobil 1 5w-30 and I've been changing oil and oil filter every 3500K miles. Am I chaning oil too often?

Yes most likely your 3500 mile change is way too often with running M1 with a quality filter. Unless your motor has direct injection where the oil gets diluted with fuel or if turbo charged you don't need to change it that often. Personally I feel the Nissan VQ40 DE is easy on oil. Send in an oil sample and get it tested and like others have stated when they got there oil tested even at 7,500 miles the oil looks fine. Personally I have 5,200 right now on M1 5w30 and when I pull the stick it looks like other cars I have had with 2,000 miles on it real clean.alecsey wrote:I am using Mobil 1 5w-30 and I've been changing oil and oil filter every 3500K miles.
