F150 guys: I think Bennys oil change is full of crap

2012 Ecoboost with 83k miles. Need a quick oil job. Normally always use synthetic and wait till light comes on truck saying to chnage oil. In this case, the mileage times up right with sticker. Last oil was motor craft synthetic.

Anyway, ask for Mobil 1 and they show me dipstic after and I glance at briefly. Thought it looked kind of dark but thought my eyes deceived me.

I roll off into vacuum area and check for myself. Sure enough looks brown.

I ask the guy to compare new oil and old and sure enough it doesn't look even close.

They offer to drain and fill again. Manager comes out and says basically that it's an issue with my engine type. Saying that the injection of ecoboosts come on "top vs the sides". Saying he went to ExxonMobil school as they taught him that. Says even if I crank it up for 2 seconds that it will be brown.

I say, ok well after you top it off let's look at it again before and after I crank. Both times no chnage. Dip stick doesn't look like brand new oil but much much better.

I think Benny's is full of shite. Not sure what they did the first time but it was almost like they didn't drain it all first time. But their sheet says they put in 7.9 quarts
