Default Fuel consumption up after oil change =(

because i'm revving it sooo much!!! man the engine feels different after getting the factory fill out of it... I changed after 5000miles to RP and man there is a difference... Now i'm not saying RP made the difference i'm sure i'd get this effect with any other high quality oil but man... my fuel consumption is up 10% and loving it... Before it wasn't so happy reving past 5k... now it flies up to 6.5k rpm... it still doesn't like the 6.5k+ though... wonder if redline or some other oil will help...

Anyone else feel this effect or is it all in my head?
