Stay away from $19.99 oil change specials , they are not a bargin. If it cost me more than $20 to do my own oil change with good synthetic oil and a factory filter. Ask youself how is a honest oil change business going to do that for $19.99 provide good oil and filter, pay a Mechanic and keep the lights on. They are not ! They are going to try and upsell you and sell you flushes with the wrong fluids that will screw up your car . Go to the dealership and spend the extra $20-$30 and have it done correctly , dealerships sell oil changes as a lost leader to get you in so they can do a multi point and sell you other overpriced services, or hand you over to sales to get you into a new car, just say NO not right now.
