Software update?

Ey today I took the Jeep for an Oil Change, and they mention they had a software update... Anyone knows what this this consist?

What ever it was, after the oil change, nitro fill tires, and update, i have gotten the best solid MPG ever 26.6 highway at 65mph ( i also have AEM intake and Gibson catback)

Before this the best i got was 23.3mpg

Re: Software update?

Did they charge you for filling the tires with nitrogen, an advantage only appreciated on racing tires?

There is a TSB for the transmission. But I doubt it effects Highway MPG.

Fresh oil can boost your MPG. Many oils get thicker as they age.

Also what was your tire pressure before and after service?

You have that backwards. Engine oil shears down and loses viscosity over time.

Check your service record. It should list the number of the update. Post that number here and someone will point you to the reference document that says what it is about.

Re: Software update?

I like to get the TSB # on the service record. Maybe Eric can give you the numbers.
