Punching it to speed
So I watch my mpg like most people do when they buy a new rig. I've read a lot about some terrible mpg in a 6.0.
I don't really drive city, just country driving. I have the EGR delete done, other than that, its stock with 120k on it.
So I get 17-20 for a full tank all around. I was getting 15ish to 18, but then I found if I get on it to about 3300 RPM's until I reach cruising speed, then just maintain it, it just does so much better. Letting it idle up to speed basically is garbage MPG, like 14 getting up to 70 and the way it goes through the gear is painfully slow and bad MPG.
I drive 70mph on 2 lane highways in mountains, lots of passes, up down, curvy. These things coast like no other, mine just seems to coast so easy compared to my old truck. So once up to speed, it just seems to maintain well vs a slow start..
IDK...just 1 mans opinion.
