Free Motor Oil

There are no O'Reillys in my area. :(

That beats the 6-cents/quart I ended up paying for Pennzoil Platinum synthetic at Pep Boys. The last time I bought some, it was $0.99/ quart.

Looking at the product data sheets, I see why.

You can be rest assured that price will go up significantly when and if hillary gets to be the big kahuna.

You will pay boy, pay big time and because you want to save earth, you will be loving it, every dollar paid, LOL.

Would you believe there are no Pep Boys in my area, and no Advance Auto either. Just O'Reilly, AutoZone, Napa, and of course WalMart ;-)

I'm surprised you say that. What don't you like in the data sheet?

Lately, both the QS oils and Pennzoil Platinum are showing better results in used oil analysis tests than Mobil 1.

What's an O'Reilly store?

Its a auto parts chain, formerly called Hi-Lo. Smaller then AutoZone & PepBoyz. I've only seen them in Texas.

For those of us who aren't good with data sheets, what did you see?

The Q Advanced only has ACEA A1/B1 approval, which is an obsolete standard, the A5 approval for the 5W30 appears to be inappropriate, the HTHS (high temperature high shear) viscosity of the 10w30 is only 3.2 CentiPoise which is inadequate protection.

The Q Torquepower doesn't even list any ACEA approvals nor do they list a HTHS viscosity. Might be okay for lubing roller skates...

Already answered in another post.

Which differs from whether or not a particular oil meets an OEMs requirements to begin with.

What the hell are you talking about? This isn't a political discussion, moron.

Does that mean it's worse than API SM-rated conventional oil and not worth using despite being free after rebate?

It -is- API SM rated oil. API ratings are pretty much worthless.

Whether you pay to trash your engine or you do it for free, either way, the engine is trashed.

Thanks.

Now I know where Built-Well is...

Larry, Quaker State's Q Advance and Q Torque are API SM-rated, the latest and best API rating. Much better than SL, for newbies here who might not know.

Their oil is not going to trash your engine, like aarcuda pretends. In fact, the latest independent, scientific tests show engines experience more engine wear with Mobil 1 oil than with Pennzoil Platinum and Quaker State Q Advance--about 67 percent more engine wear. Just so you don't think I'm favoring Pennzoil, let me say that Halvoline, Amsoil, Motorcraft, Castrol Syntec, and others also show much less wear than Mobil 1.

And yes, we've mentioned before that since about 2003, the Dutch company Shell has owned both Pennzoil and Quaker State. However, I'd rather give my money to Dutch Shell than to Exxon.

In my opinion, we're paying billions for ExxonMobil's war in Iraq; why should we increase their profits by also buying their oil?

I admit I have been using Mobil 1 this past year (and it's in my engine right now), but now that I know Pennzoil Platinum is better than Mobil 1, I'm dumping the Mobil 1 at my next oil change. I'll be saving money and I won't be supporting their war that's costing us billions of dollars and thousands of lost American lives.

I already bought a 5-quart jug of Platinum last night to support our troops :-)

O'Reilly Auto Parts is in about half the U.S. states, including Missouri, where I live. In fact, its headquarters is in Springfield, Missouri. If anyone's ever watched "American Hot Rod" on TV, the show about legendary California hot-rod maker Boyd Coddington, you will have seen O'Reilly banners hung in Boyd's garage :-) You also see Amsoil banners in his garage, too. And Reeses peanut butter cups also sponsor Boyd Coddington hot rods. Only the best for Boyd ;-)

Could you post a link from an independent source that substantiates this.

Ditto.

Well, as mentioned before, lots and lots of Used Oil Analyses (UOAs) show Pennzoil Platinum (PP) and Quaker State (QS) as being much better than Mobil 1 in protecting your engine from wear.

I won't rehash the details here, other than say that respected tribologist Terry Dyson of DysonAnalysis.com (with over 30 years of experience) has said the same.

And there have been independent studies showing Mobil 1 (M1) not doing as well as PP. I've lost some of these references (perhaps I should have posted them here when I first read about them), but one that I remember off-the-bat can be seen at Amsoil's web site at this page (look at the graph midway down the page):

The Amsoil product is not easy to find; it's not an off-the-shelf oil like Platinum and Mobil 1. But you'll see that the easily available Pennzoil Platinum, Halvoine, Quaker State, Motorcraft, and Castrol all performed much better than Mobil 1.

So why spend the extra money for an underperforming oil?

Notice that the wear in millimeters for Mobil 1 is greater than

Regarding the synthetic versus conventional debate, please keep in mind that careful, scientific studies have shown that 90 percent of engine wear occurs at cold startup and within the first 15 or 20 minutes.

A non-affiliated PhD writes the following about a paper by Schneider, et all, called "Effect of Break-In and Operating Conditions on Piston Ring and Cylinder Bore Wear in SI (Spark-Ignition) Engines":

"The rate of wear is much higher within 15-20 minutes of start-up than after reaching normal operating temperature. There was a lot of data but I conclude that the initial start-up time period (first

This is another reason to use synthetic oils, since they're much less thick at very cold temperatures, and can start lubricating your engine better and faster during wintery cold temperatures.

Notice that the wear in millimeters for Mobil 1 is greater than 1 mm ( >1 ) even though the graph ends at 1 mm.
