This is a great value for owners of vehicles that use synthetic motor oil. Generally, most oil changers charge a fix price for oil change up to 5 quarts. Unfortunately, our car needs an extra quart.

Speedee charges $10 more for that one extra quart!

Anyway, most places charge extra for the synthetic oil so you can save some money by buying it from Costco when there’s the extra discount and taking it to the oil changer.

You can call around and ask but generally, I think you can save $10-$20 by doing this.

At the very least, if your car needs that extra quart, bring it and save $10!

Let us know if you’ve done this or if you’ve any tips to save some extra bucks!
