Re: OOOPS! Used the wrong oil
I'll agree with the other posters regarding leaving the oil in there until
the next change. Before your next oil change, I will recommend looking in
the owners manual for the oil viscosity recommendation chart... you can
decide which viscosity range is best for your local conditions.
Modern engine technology has viscosity selection as being more important
than it has been in the past. I've seen improper viscosity pump lifters up
and holding valves open... rare, but still happening.
That you have selected a synthetic based on PAO stocks is good.... and may
even be a choice for continued use. For this oil, one big bragging point is
reduced viscosity change in temperature extremes.....

Should I drain out the Mobil 1 (priced like a real
