The synthetic oil alone is like $75 so you're telling the world you put cheap oil in your whip?
For a complete system flush with high grade Synthetic oil, it will cost at least $200 to $250 but more if you get the other fluids done too.
No oil change should cost $250, synthetic oil is synthetic oil. The symbol on your car doesn't change that or dictate the price. I swear dealerships be getting over on people.
