Maybe I am just not good at searching, but is there a single location on here that discusses the best MPG additions? I have done a few mods to save money but want to pull my 5th wheel this summer and with $4 prices coming in SoCal it may be a boring summer of polishing the shiny parts! I am considering a vegy burner, and propane. I have cleaned up the intake and exhaust with CFM horn, s&b filter, 6inch magna flow. I run Edge juice with attitude. I am still in the mid teens empty and around 10 towing. It is a mega 4x4 with a lift and 35's but still! Any other suggestions?

 

Propane as a power adder? Yes! As a fuel saver? No!
Costs to get it installed ( if done professional) and propane costs per BTU (Diesel 130.000BTU per gal versa Propane 91.000BTU per gal) are to high compared with Diesel.

I don't know about veggy oil in a 2006. I only would use it in a two tank solution with a coolant preheated line.

I see only chances by decreasing wind and rolling resistance.

 

Your not going to get a Hugh Truck thats lifted with 35's to get great fuel mileage. Take it back to stock height and stock tire size and you will see a big difference.

 

I was actually thinking about coming down a bit on my ride height. I bought it with 6" spacer upfront, and 3 1/2" blocks in the rear. It rides like crap! Been looking into Carlie suspension that would actually drop it down a bit. But the cost is kind of prohibitive.

 

Jest save your money and spend it on fuel.All of the add ons will cost you much more than a little fuel.If you Fugger the cost you would have to drive it many miles to come out on top. === Good luck

 

Another good point! But then I dont get to tinker!

 

swap to synthetic oil in the enging tranny and rear end, would probably help some

 

I just had a look into the automotive handbook from Bosch.
Due to their rules you can expect on average a:
- 6% less fuel consumption if you reduce the weight by 10%
which should be difficult to gain
- 3% less fuel consumption if you reduce wind resistance
that means no open windows or huge rear mirrows or a bed cover when the bed is not used.
- 2% less fuel consumption if you reduce rolling resistance
that means pure thin street tires with a good street thread- no aggressive offroad tires.
Avoid short trips with no engine warm up.

 

I am running AMSOIL with a twin filter set up. Never have to change oil again, just filters. Those other suggestions are good though. I am planning on doing my transmission next. Adding a deep pan for more cooling and going synthetic.
I can not think of how to do any of those Deezel stink3r!
Thanks for the responses, keep 'em coming!

 

Whoever told you that you never need to change your oil again has fed you the biggest line ever.

Oil still breaks down. It may not have the contaminants in it, but it will break down and not have the lubricity of new oil.
