Is it Summertime, summertime, summertime Fuel Yet?

Have you noticed the boost in POWER now that summer fuel is at the stations? Dunno about anyone else on this board but with the temps reaching above freezing these past couple weeks and the change over to summer fuel my car has the feeling of 25 extra ponies under the hood and 50lb extra torque.

Is it because the fuel reaching the injectors are finally warm and the operating temps have reached optimal these past weeks as well?

Is it because my butt has thawed from a freezing cold winter and the seat of the pant is back into sensation?

Is it because I went to Diesel Kleen from Power Service and the certane has now profited to the point where a difference in combustion has off-set prior performance?

Is it just Summer Time?

No real increase in power, but mileage has increased last couple weeks seems like.

Ditto on the MPGs. I've jumped back up to my 47+ I was getting last summer/fall. All winter it was about 44 average.

I'm thinking it's the summer fuel back in my tank.
