Switching to Synthetic from Conventional
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 int...
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 ...

Did Switching from Synthetic to Conventional Oil Contribute to Engine Stalling and Hard Starts?
Does switching from synthetic oil back to conventional oil cause any engine problems? I switched my last used car to a high-mileage synthetic when I got it and it ran fine. But one of the next times I...
It is unlikely that your problem as described was oil related. Certainly hard starting/cranking in cold weather could be impacted by using switching oils especially if they were different viscosities....
