The price (west coast) the local WalMart is as you said ($22. per 5qt container 0w30 Mobil One). I bought a container to keep on hand for 0w30 applications back fill.

Same outfit that supplied me with the Quaker State "Q" synthetic. Just yesterday, I got my $10 rebate check. The five quart jug is still sitting on the shelf in the garage, waiting for me to "pick a vehicle".

So what was the ultimate cost per qt for QS 100% PAO groupo IV basestock oil? The Mobil One was/is 4.40 per qt.

I need a review: is the 5 quart jug of Quaker State synthetic oil that I bought at Walmart any good or not? Should I just forget it and stick with my Exxon SuperFlow normal oil for my 03 LeSabre or can I put it in for an oil change interval during the hottest part of the summer here in W. Ohio?

What exactly do you want to accomplish?
 
If I had decided to stay with conventional oil 5w20, 10,000 miles OCI for the Honda Civic, my pick would be the Exxon Mobil Super Flo (5w20). It is a very high quality product. The price per quart (special store sale AND after rebate, if I remember correctly was .66 cents per quart). This made it hard to decide to switch to Mobil One 5w20,0w20. $22. per 5qt container.
 
What is the price for QS? I am guessing it is a hydrocracked group III product.

So given that most folks will keep their cars 9.3 years and most likely LESS, most folks do 3,000 to 5,000 MAX OCI's. WHY BOTHER... would be my take!?? Honda OEM OCI recommendation is 10,000 miles on conventional oil and 20,000 mile oil FILTER changes.
 
back in '80 my friend bought a '68 Firebird from a co-worker. The co-worker had bought a new Firebird for himself and a new GTO for his wife back in '68. He didn't believe in air filters or oil changes for either one. All the S. Fl. sugar sand ingestion by the 400 in the Firebird worked in unison with the no oil changes well. He had to add lots of oil and that kept it changed. My friend bought it with under 50k miles on it, all original, rebuilt the engine slightly over and with the granny tires, a 4 on the floor, and posi, he could break it loose for about a second at 50 mph with a 4th to 3rd downshift with 4 of us in it.

After the rebate, my 5 quarts of "Q" synthetic came down to $1.60 per quart, as I recall. That does not include an allowance for postage, paperwork, etc. To top it off, I do not know if the product is PAO group IV or not. Would you dare run it say, 10K miles in either a 4.6 liter V8 Mercury Mountaineer or a 3.0 liter Ford Escape V6? I would not be doing an analysis.

Without any in depth research, I would not hesistate to recommend the full oem OCI for the "QS synthetic". More than likely, the QS S meets the oil specifications for your two engines.
 
Now I am not saying that QS is not good. I do however have close to 1 M miles on Mobil One and with a min of 15,000 to 25,000 miles OCI's.
 
In the context of things, I would call this a past (personal) bias about QS, Pennzoil and Castrol. I have scraped more than a few engines of the sludge that had steady diets of the above products and with 3,000 miles or less OCI's !!!

That bad experience was with conventional (dino) oil, wasn't it?
 
Here we are taking about a Group III synthetic that, although not quite equivalent to M1 is still a synthetic oil.

"Here we are taking about a Group III synthetic that, although not quite equivalent to M1 is still a synthetic oil."
 
Still a synthetic oil? In name only, in fact, in name only here in the States; Group III oils are not allowed to be called "Synthetic" in Europe.
 
Best regards,
