In my local paper is an O'Reilly ad offering a maximum of
6 quarts of Quaker State oil (Q Torque and Q Advance) for /free/ after rebate. Each quart is regularly $5.69.
Q Torque and Q Advance are the good stuff, the synthetic Quaker State.
A $35 value totally free after mail-in rebate. I get the feeling that O'Reilly stores across the country might be running this promo. Get it while you can! =
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...
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 ;-)
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):

True, Amsoil is far from being independent, but if you read the small print in the Graph's Title, you'll see an "independent lab" is mentioned. The Federal Trade Commission (F.T.C.) and Amsoil's competitors (Mobil 1, Redline, etc.) would force Amsoil to remove that graph if it weren't valid and from an independent lab.
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
1 mm ( >1 ) even though the graph ends at 1 mm.
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
20 minutes) result is 100 nanometers of wear whereas the steady state wear rate was only 4 nanometers per hour thereafter. (Hence we should be concerned about start-up oil thickness more than running thickness." [END QUOTE]
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.
