I was going to put this up as a poll, but I figured there may be more options than I would put in the poll. Lets hear it. While we are at it, whats your oil of choice?

Autolite and Pennsoil with STP oil additive. I plan to go Mobil 1 at next oil change. I use Castro Syntec on the goat.

Anyone else tried the E3 brand of spark plugs. They really do make a difference. No more bumpy idle at rest and they really do add HP just like they advertise. I get over 18 MPG with my 351C 2V on the highway and once I finish lowering the front end I expect to get even better gas mileage. BTW avoid the mazdaspeed3 if it lines up with you at a red light. That little SOB is damn fast. 280+ HP and all sorts of aftermarket stuff to make it faster and it weighs nothing.
