Where did my oil go?

[Hellbent]

also running this in my renix the last two oil changes, didn't make any difference at all in mpg versus the mobil 1 5-40 that i used previously. rotella's been on sale recently, so....

I'm running Rotella 15-40w but.. I bet its not great for mpg.. No leaks and very little burn off though.. even at 270k miles..
