For what it's worth, I am guessing that you put the correct oil in the engine, especially since you said it was a sealed cap container, and you broke the seal. There is a big difference in viscosity between say 10W-30 (if that is what you were used to), and 0W-20.Didn't say it was Red, seemed runny than what I'm use to and had a light pinkish color. But was out of a brand new bottle of 0w20 Pennzoil. Also Dealer is not blaming me for anything, so far they are on my side.
Also, if it was some sort of other fluid, say transmission fluid, I am sure the dealer's mechanic would have noticed that by just checking the dipstick, or draining a little oil.
Since the dealer is not blaming you for anything so far, I would guess that this is NOT your fault.
Please keep us posted. I am sure we are all interested in updates from you.
