All Oil Created Equal?

|DIY Oil Changes|
I realized that I needed some oil in my car on the way home from work one day and stopped at a little auto parts store. The only 5W-30 brand they had was "CarQuest." I was hesitant to buy it because I only use Valvoline brand. But the salesman told me that CarQuest is the exact same oil - that Valvoline makes it under this name and sells it for less. Could this be true? I have doubts that this would be the same quality. What do you think?

A lot of the oil manufactures sell their product under private labels for auto stores. For instance, I was informed that Pep Boys oil is actually manufactured by Castrol, Associated Auto / Auto Pride is made by Valvoline. So it could be true that Car Quest is made by them. Now, it could also be true that he just told you that it was your brand to make a sale. None the less, one quart when the car is low will not make any difference. The slight differences in the oil are far out weighed by the damage that could be done on an engine running low on oil.

Editor's note: The following was received about Castrol regarding Bob's answer.
I read your response to Jenny the other day on "The Car Care Clinic," and although we all enjoy reading your comments and answers, we noticed that your response to Jenny contained an incorrect statement: "... Pep Boys oil is actually manufactured by Castrol ..." Castrol does not manufacture motor oil for Pep Boys or any other auto retailer or mass merchandiser. Castrol has its own brands: Castrol GTX, Castrol SYNTEC BLEND and Castrol FULL SYNTHETIC, which it markets and distributes to major retailers and specialty stores. Those outlets carry our products under our label only. Now that you have this information, please feel free to share it with your readers in the future.
