I pretty much don't change my own oil anymore, I just collect those oil change special coupons that NTB sends out, and let them deal with it. But, (there's always a "but").
My beater Miata was abused by my son, who sludged it up, never changing the oil, despite my reminders. It's a real tribute to Miata that the engine still runs and uses no oil.
Anyway, now that I have it, I'm making up to the old girl by changing the oil myself, frequently with cheap name brand oil. It always comes out black as night, so I know there's a way to go yet.
Today, I made a change, and was about to pour the new oil in, when I noticed that the 5 qt of Quaker State looked really funny. I then realized that I did not have to break the cap seal. Some dingle-berry must have done a 4 qt change, filled it back up with water or anti-freeze and took it back to walmart.
To wally worlds credit they exchanged it for me without a receipt. I made sure to tell them not to put it back on the shelf. If I hadn't noticed, my little Miata would be toast now.
I called up my buddy, who mechanics for a living with my story, and he admitted that like me, he never thought to check the cap seal before.
So, pay attention if you buy your own oil changes. Look at the caps.
