Autozone-branded full synthetic

Yes, it is almost certainly from one of these big manufacturers, which is OEMing it for Autozone.

Yes. The Castrol Syntec is this way.

It is almost certainly equivalent to one of those major-label brands, but only the Autozone buyer knows which one it is. And that may also change the next time they place an order, too.

I'll point out you can usually get the major brands for a similar price if you buy enough at a time. Sometimes that can be an awful lot, though.

IMHO, if the motor oil carries the required API certifications, then you are likely in good shape.

Having said that, I use nonsynthetics in my cars but there are some brands of nonsynthetic oil that I won't use anymore even though they carry API certifications.

I have observed, or believe I have observed, increased tendency to lacquer or dirty the engine by some brands. I believe this to be a consequence of the additives package used, not the refined base oil.

Does the saying 'there is a sucker born ever day' mean anything to you?

I refuse to pay the extreme high price for an 'imitation' 'synthetic' oil.

Sure the real stuff is likely half worth the extra money, but to go to court and play with words just so you can slap a label on a bottle and charge 4 times it's worth is total bullshit in my opinion.

That is like when they first came out with the 'imitation' crab meat and tried to pawn it off as 'crab' meat for the same price. I believe enough consumers balked at the BS so they had to lower the cost down to the price of fish, not the price of crab.

Have a look at or subscribe to Lubes ' Greases magazine,

If you are concerned about the truthfulness of the API claims made on the oil can why don't you contact Autozone and ask for the technical data supporting those claims.

But even the cheapest conventional oils carry those same API certifications. :)

Every store brand conventional oil I've seen was made by Valvoline/Quaker State, except for Wal-mart's, which came from Specialty Oil or Specialty Lubricants.

Do you mean it's only $0.27 a quart? Because I paid a whopping $0.38/qt for a 6-pack of Pennzoil synthetic. If there's a Pep Boys in your area, their Sunday ads have been listing a lot of good rebate offers recently.

The word combination "Imitation synthetic" has a paradoxical ring to it. On the other hand, so does "real synthetic" ;-)

I believe you can find the manufacturer of this oil by looking up the MSDS label on the stuff and it should tell you who manufactured/bottled the oil for Autozone. I'd bet money that it is manufactured by Quaker State, but I'm not going to take the time to look it up. However, that does not mean that it has the same identical composition as Quaker State synthetic oil. It could be slightly different.

If putting a synthetic or at least a synthetic labeled oil in your car makes you feel good, so be it.

And what would those oils be that you frown upon?

Partially-hydrogenated vegetable oil, for one. Not only does it cause heart problems and arteriosclerosis but it could really mess up your engine too.

Damn! I didnt know this was the cooking forum? I thought it was about motor oil...

In Scotland, there was some chip shop recently that was found to be using used motor oil for frying fish. It all goes around, you know.

In Scotland; what size autos are the most popular (cc/litre), and the biggest selling brand of motor oil?

I would assume Rolls-Royce, and Shell Rotella.
