Premix your 8, get better gas milage

[fikren]

Well I started premixing my 8 and noticed an improvement on gas milage. I am taking my numbers based on the 1/4 tank marks of the fuel level gauge.

Between all the tests I have not changed my driving style, have not been taking different driving routes, and have not experianced any traffic or long time idling periods that would make the numbers change.

Prior to premixing I was seeing on average about 50-53 miles per 1/4 and this was consistant through all the 1/4 tank marks and also mainly based on the 1/4-1/2 tank, 1/2-3/4 tank, and 3/4-full tank. I never ran the car empty enough to justify using the empty-1/4 tank for my numbers.

So essentially at each 1/4 mark I had traveled somewhere between 50-53 miles.

After premixing I am seeing 55-60 miles traveled per 1/4 tank of gas. This is equating to 15-20 more miles per tank of gas while premixing then then when not premixing.

So not only can premixing offer you increased apex seal lubrication but can also help on the gas milage. Others have also said that premixing will make your car idle a little smoother. Since my engine is pretty much new (~1400 miles) I really haven't noticed any difference in the idle.

Just thought I would share.
