How Far Can Oil Drains be Extended with Mobil 1?
I have a 2006 Chevy Trailblazer that I use for work. I put over 40,000 miles on it per year with all types of driving. I currently change the oil every 3,000 miles using quality mineral oils. I am interested in switching to Mobil 1 full synthetic oil to extend the drain intervals out so I'm not changing the oil every 3 weeks. This vehicle needs to last me for 200,000 miles. I currently have 82,000 on it. If I switch to Mobil 1 full synthetic, how far can I extend the drain interval out to recoup the much higher cost of Mobil 1 and get 200,000 miles out of this thing?

With Mobil 1 oil you can easily go between 7,500 and 10,000 miles depending on your driving conditions. We recommend that you start increasing the ODI gradually. You are the reason we created Mobil 1 Extended Performance oils which we recommend for up to 15,000 miles between drain intervals.
