I've got an oil change coming up in Nov. on my 2004 vibe. I thought I'd try something different for a change from my uasual pp 5-30 and Pureone filter oil change to QSUD 5-30 and maybe a Fram Extended Guard for the filter. I do about 6000 miles/6 month oil changes. Next oci won't be due until May 2012. The wife drives 5 miles one way to work and I drive 14 miles one way to work on a hilly windy road. Duty is split with a second car. Depends which is last in the driveway. She leaves for work first and I get home last. Think I'd be okay or stay with Pureone? Thanks!
