P0171 & P0174 Runnig rich, both banks

Any idea what would set this DTC. Had oil changed yesterday. Could it be posible that it might be burning off some excess oil? I see on invoice - 8 liters of 5w-30w. About 1/2 ltr more than needed.

Check those codes; the numbers you gave are for lean - not rich.

If you are convinced of the connection between the oil change and the codes, there are some items to check under the hood when both banks are reported lean; vacuum leaks, vacuum hose knocked loose from a connection, PCV valve, oil filler cap, dipstick.

Did the oil change dudes have the engine air filter box open?

Yup. It was loose. Tightened her up and codes gone. A few WOT's around the block and still gone. Gotta love this site. Thanks Jim. I owe you a beer.
