Hi everyone, Thanks for your input. Yes, it's 190 miles per weekday, or 45k/year or so. It's nearly all highway miles, and the transmission is a CVT, so the RPMs are quite low at higher speeds. That's one of the reasons the car can get close to 40 mpg and still have a decent amount of pep. I'm...

Hello everyone, I have a 2013 Altima with the 4 cyl QR25DE. This car is driven a lot -- on average, 190 miles per weekday. The OCI called for in the manual is 7.5k miles for "normal". This equates to an oil change every 2 months. The dealer is cheap, but instead of using OW20 (presumably called...

Hi everyone, Curious as to your thoughts as to whether a 10k OCI is reasonable for our commuter vehicle -- info below. We've been doing a 10k OCI the past 3 oil changes with Valvoline Maxlife synthetic or Synpower synthetic (whichever is on sale), and it seems to be running well with no issues...
