Fuel mileage test results

Well I did these two things a few weeks ago.

I changed the rear diff fluid to royal purple 75W-140 and cleaned EBP sensor and tube
http://guzzle.rbmicro.com/ebps.html

Prior to doing these things I hand calculated my mileage was getting 12.8 MPG driving both city/hwy.

After doing these, I hand calculated again and am getting 14.8 now driving the same route to and from work.

Just wanted to pass it along!

Yes I do.. I'm on 35" tires too. 14.8 isn't that impressive I know, but its an improvement for sure..

Re: Fuel mileage test results

Improved MPG is always good but I suspect all of your improvement came from getting the EBPV to work properly (or more correctly quit working when not needed). I went the other way. Mine blew from September to May so I electrically disconnected it to avoid monkeying with a high-maintenance item in mid-winter. Of course I freeze my butt for 10-12 miles before the engine warms up. This is on my to-do list.

I donít think one brand of synthetic gear lube is better than the other. Oil salesmen probably hate me.

BTW, I always consider a valid MPG test to be at least four fill-ups where on the initial and last test you eyedropper the tank completely full. Averaging it out over four fill-ups minimizes inconsistency in how you fill the tank and averages out your duty cycle toa consistent profile of how you drive. I never trust single tank numbers.

My EBPV has actually been removed, the pedistal was replaced. I was refering to the sensor at the front of the HPOP resivour with the tube that goes to the pass side manifold, just so there is on confusion..

Thanks for the post Dave, always good info!!

I bet the Tires and Turbo don't help your MPG so considering that 15 mph isn't bad...

Yeah I know you're right on about my tires.. Don't think the turbo has anything to do with it.
