OK I am trying to figure out if I need to address my MPG situation. The dealer told me I could get up to 20 MPG . But I dont trust dealers any farther than my ten tear old son can throw them. but I just had to have this 2000 EX. I figured it would get 18 since it was a diesel. I am only getting 15.5 MPG in general and 17 on the highway trips. Do I have a problem or is this what I should expect. The 15.5 is 90% highway. The 17 MPG is with the product called DIESEL KLEAN. PLEASE REPLY with your average and highway MPG. THANK YOU.

 

Have you changed the fuel filter since you bought it? Air filter? Those two things will make a big difference. In addition, if you keep the RPM low and don't gun it on starts you will see a huge difference.

 

Rackpatrol, how fast do you normally go around town and on the freeway?

 

about 16 on average on my 2000.

 

How many miles do you have on it?

 

My stats....

01 X PSD w/ 49K miles
If you believe the trip meter (hold your laughs, cuz I know it is way low)...
15 or so in the city
18 highway

I did the math on a long trip from Texas to Florida and I got close the 20....

 

Rackpatrol?

 

I get like 11.5 says my gauge and I think it is close to correct. I put a high performance air intake on it a few months ago and really no change. What can I try??? I have the 7.3 PSD engine!!!

HELP!

How fast do you go around town and on the freeway? Have you run any Diesel Kleen through your PSD? How long has it been (miles) since you've changed your fuel filter? All of these could be factors that lead up to why you're getting such bad mileage. If you don't have a heavy foot, you should be getting around 15.5 to about 16 around town, and about 17.5-20(if you're lucky) on the freeway.

 

Thanks for your reply. I don't drive crazy since I can almost see the gas guage move. I purchased the vehicle at 28k and it has 33k now so I will replace the filter today. I will also put some Kleen through it and report back! Thanks for your help. I live in a hilly area and use bigger tires in winter and 20" low profile tires in summer.

If you ask me, I think its the bigger tires as well as the 20" rims that are killing your mileage. If you can find the silver bottle of Diesel Kleen, use that. Otherwise you'll have to go with the winter blend "white" bottle. I hope the Diesel Kleen as well as the fuel filter change makes a difference.

 

I have an 00 X 7.3 PSD and get 22.5 MPG at 55-65 mph of freeway driving. It drops to 19.5 at 75-85 MPH. When pulling my 30' toy hauler I usually get around 10.5-12.5 depending how hard I'm accelerating. Oh...did I tell you about my Diablo chip???? That made a huge difference in mileage and HP. Best $500 I've spent.

 

Is this according to the overhead computer or you doing the math by hand?

 

It works out about the same with my computer animated MPG guessmeter as it does with the actual mileage achieved.

 

I installed a Superchip MicroTuner today and put it on the tow mode and was getting 29.9 MPG on the interstate at 70mph. Around town it went down to about 22 mpg. This made a huge difference.....highly recommend.
