Jay,

I truly appreciate you quoting me, maybe next time you could be more careful on the edit.

You referenced I called L&N and next was the response that was said from Driven and omitted the L&N response.


Here is the Driven response, cut & paste no edit.

“”Then called Driven Racing Oils @ 855-565-5650
Asked question # 1 and he suggested I speak with Scott in the technical development lab.
So, I asked Scott question 1 His answerer was the following.

“I am very familiar with the chemical structure of Mobile1. Being than DT & Mobile1 have the same base oil it is not a problem to change oil at an oil change. He said I can tell you how this comes about. If you change from an Esther based oil like Red-Line to Mobil1 or DT you would need to do a flush. If you do this without a flush you will get 40% decrease in Horse Power due the leakage on the Ring Seals and then folks think this oil stinks I’m going back to Red-Line.””

I have read about going from Mobil1to DT40 on several forums finding conflicting information. So I called L&N and DT40’s manufacture Driven to move beyond the conflicting info and Driven who should know if their oil needs a flush. According to Driven from Mobil1 to DT40 no flush required.

Thanks for a good laugh before going to bed.
