Has anyone used this oil for this long before changing oil. I was looking at this oil on their website. They say not to change your oil for 25k miles or 1 year wichever comes first. It sells for 5.85 a quart. I think this is a good idea for me bc i hate changing oil and dispossing it. Also I thnk this would be cheaper in all and its full synthetic.Please let me know how you like it.

 

first of I used to use this oil and we regularly sent in oil samples for testing. After about 7000mi it showed we needed to change oil i wounldn't recomend going over 6000 but it is good oil. "depending on climate" i change oil every 2500-3000mi
