6.2L fuel

[_CROW]

Is anyone running e85? If so, what kind of MPG are you seeing?

 

What about MPG difference between 93 and 87 octane?

E85 is not an approved fuel for the 6.2.

I run it when I can.  I see a 4mpg drop in economy.

The 6.2 is not offered from the factory to consume E85 but there are aftermarket companies you can go seek out for a conversion kit.

 

Here is one such offering:

You can't program 2019+ computers with the 5.3/6.2 and the DFM, 8/10 speeds, so that kit is useless.
