Yeah, that is a method, Cfletcher. Welcome to the forum!

Scolesy8, what's your gear ratio?

Re: 6.0 mileage increases.....

16.5 to 17 mpg average hand calculated hwy/city and I don't think it's that bad! It improved quit a bit when I hit the 200,000 km (125K mile) mark.

Re: 6.0 mileage increases.....

Re: 6.0 mileage increases.....

Well...

My gas engined tow rig was getting 6.5 to 8MPG with its best being right around 8.5MPG. I went to a diesel rig, in a heavier chassis, and my MPG was 10.5 to 12MPG with some in the 15's.

For me, that was a way to reduce cost, even with the extra cost of diesel fuel and the additional oil required for oil changes... If I can spend less and do the same work, I'm looking for that efficiency to maintain as much money in my pocket or in the pocket of my business so that I can capitalize on other opportunities.

I don't know on the EGR delete. Some say it does, others seem to not be concerned, and others seem to say no difference. I think that some tuners can be set to reduce the EGR once it has warmed up the coolant, which could be a good use of all the heat in the exhaust after start up when the engine is cold.

My current van has an average MPG of just under 19MPG. I've got the stock sized tires, and the rear gear ratio is 3:55...automatic transmission. I don't do a lot of hauling, and I don't use the van like I used my other vans. I bought this one well used...a survivor...with 398k. EGR did need to be replaced. Seems to run strong. I had two 7.3's before, and the 6.0 scared me, but I'm doing better now...at least I keep telling myself that.

At speeds just below 60MPH, I think the engine turns just under 1700RPM's. And at just below 70MPH, the engine R's are under 2000 yet, if I remember correctly from my drive home.

I've put on taller, wider tires on my one van, the bus, and, while it allowed me to reduce the engine RPM's at the same speed, I saw a reduction in my MPG. I figured that was the result of all, some, or one (or none) of the following: van became too tall and increased wind resistance, van was too tall and too much air was going under van that increased drag, larger tires had extra weight that took more power to move, larger tires had extra width that increased wind resistance.

If I'm going to make a change this time around, one might be in going to a narrower tire with the same diameter. The stock tire is a 245/75R16, and I'd consider a 215/85R16. Weight would be reduced, and width would be reduced while maintaining the current "as designed" gear ratio and overall height.

Considering ideas on building an air dam.

I enjoy the stuff made by DP Tuner. I think their programs has a little better shift strategy than stock strategies...seems like the OEM ones don't lock up the torque converter soon enough and they hold the RPM's out pretty high before shifting...my thoughts at least. A manual transmission would be ideal, but converting a van would be an expense that I don't want to tackle.
