It's hard to say 100% not knowing how dirty your oil was before you took it in, how dirty it normally is and history of your outfit.
I'd say they forgot. Sadly, with a Honda, it's a real pain to get under and look and see if the filter is new.
I'd prob try to get a look at the filter and then go from there.
You oil should not be that discolored that quick unless;
1. They did not change it.
2.
They did not drain all of it out . (I've seen iffy-lubes pull the drain plug and then change filter, once filter is on, put plug back into pan with FLOW still going on..)
Running Dino all of it's life the engine is not going to be dirty unless you were changing not often enough. (Like every 4-6 months and 4-5k miles)
Syn is not a cleaner so your oil will not get dirty quicker with it.
When you got your oil changed with dino, how long did it take before it was your photos color?
Take care, Bill
