After going to the Great Canadian Oil Change on Pembina Hwy and dealing with a rude worker their, I had noticed that my car was leaking oil not long after. They did not put the oil plug back into my car properly. If i had not noticed it and gotten someone else to look at it, the plug would have eventually fallen out and could have wrecked my engine. I am writing this because this isnt the first time I have heard of this happening. My friend also had a similar experience although his car broke down after they screwed him over as well.
