I used to get 16 mpg or so back in Mexico at high altitude with 92 octane Premium from Pemex, but the real reason is all the modifications I did, that I am sure of has a great deal to do with it. I want to see what local pricing is around here in Bradenton, to see if I will uncork part of my exhaust perhaps as soon as Monday, and that should give me some more mpg.

I should mention that on Friday I went down to a local tire place here and got the nitrogen pushed up to 38 psi all around. The heat seems to have a greater tire pressure here than at high altitude back in Mexico, so I left it at 38 instead of 40. Even nitrogen can have its effects, but not nearly as much as air. So we will see how much my MPG changes now, as I used to have it at 35 for my trip over here.

 

This is the sound on the road, http://www.youtube.com/watch?v=S8z3KOqQgnw

and this is in the driveway of my friend Michael's house, http://www.youtube.com/watch?v=Zf7_RkgqdW4

Michael is incidentally carrying some of our favorite oil (shown below), though all 8 quarts we bought are going in his Z06 Vette (that's how much it takes). Found it at 2 local AutoZones running a bit over $6 USD a quart.

But that wasn't the only fluid that I got as I struck gold early this morning.

 

Could it be?

 

Indeed it is, Amsoil ATF, got it at Carquest here in Bradenton for just a bit over $9 USD a quart, and bought 13 bottles. Well worth every penny. Hope to do the first drain and fill sometime later today or perhaps tomorrow morning.

Still haven't got to my exhaust issue. I plan to remove the Kire muffler I have below (I like it though), but at sea level I just have had too many issues with the pressure in midrange and need something more direct. I think that the BMW muffler I have on the back is doing a decent job. Though indirect it is large enough to take in the exhaust and shovel it out the back, and given that it is the muffler and not the resonator, this helps all the more.
