The links stated, "The "synthetic" oil business is regarded by many in the oil industry as a "religion" whose followers are holding a belief that "synthetic" is somehow superior, but lack the actual proof."
There is actual proof that synthetic lubricants are superior in many ways. 100% mineral oils cannot get extended change intervals as many European versions of fully synthetics do. The high boil points mineral oils cannot reach. The cleanliness inside engines cannot be achieved by mineral oils. API do not mention synthetic, or anything else, just the protection an oil should give. How it is made is not their concern. I know of no 100% mineral oil that meets API SN.
I thought it may not be the best link to provide.........you are correct, the slap was against Amsoil, that had the marketing program. I did not mean to suggest that synthetic is not the best. Years ago I had twin 6V53 Detroit diesels in a boat. I tried to use a farm store brand and had increase useage. Switched back to Shell Rotella and solved the problem. Living here in a cold winter climate I like synthetic because the pour point is better for cold starts.
I do get it. You spent a week telling us how special your Toyota station wagon was because it's top speed was over 100 MPH.
You never got it. The Toyota had a small engine that was fast and very economical. You were defending uneconomical cars with overlarge engines. You never got it.
What about Group V oils like Redline? Are they not fully synthetic in the old school sense of the term?
That said, I'm not sure it makes any difference what feedstock you start with, what counts is the capability of the finished oil. One brand advertises they make the oil from natural gas rather than petroleum - I'm not inclined to think this is anything other than advertising hype.
I think the idea of using a Pennsylvania sourced crude is stuck in the '50's or earlier. Modern refining techniques can make a good lube oil out of most any crude.
Why even think about saving a couple bucks buying store brands when you can get nationally reputable brands for a few bucks more? Everyone heard of Pennzoil, Quakerstate, Valvoline, Mobil but I doubt most people know Supertech.
If you are hurting for money and $2-$5 is an issue then you shouldn't own a vehicle.
Yep, wouldn't use Penzoil if I had to.. I use to work on Panteras and one of the Mechanics there use to work for one of the Indy car crews.. Their major sponsor was Penzoil.. According to the rules you had to use the sponsor product in your vehicle... They used the least amount they could get away with.... Becuae it caused a hard varnish inside the engine...
His dad also worked on one of the crews that STP sponsored and they used as little as they could.....
So just cause it is a brand name doesn't make it any better than as off brand at times

Pennzoil is a quality oil that is trusted by a lot of people and recommended by mechanics all over. You're right the brand name doesn't make it better then the off brands...independent lab tests prove it's better. If you read the data on Pennzoil vs Supertech conventional oil you will see what is better. The Petroleum Quality Institute of America
I also just read Dr. Robert Sutherland of Pennzoil is one of the worlds leading engine oil chemists and helped develop the latest GF-5 standard for motor oils.
That's another reason for me to trust Pennzoil as a quality product.

Interesting site. There are a few mineral oils that do meet API SN. That does not mean they are equal to a fully synthetic oil.

Where's the data? I've yet to see any proof that Pennzoil is better than Supertech (not really an "off brand" as it's made by Warren Distribution).
The only thing that I feel is somewhat certain is that SN GF5 oils regardless of brand will perform 99.99% the same. Supertech and conventional Penzoil are both SN GF5 oils. Any other claims are probably just marketing or in this case, someone blindly shouting that what they like is #1!!!!.
Change your oil every 5-10k and no automobile motor oil sold by Walmart will cause you problems. Your car will probably fall apart before you have an engine problem that can be linked to the motor oil used.
Some 100% mineral oils meet API SN. A big but, they only appear to test the oil when new. MIneral oils can serious degrade after 1,000-1,5000 miles. Testing is needed after 2,000, 5,000 miles, 9,000 miles, etc, in normal mixed driving, putting the fresh oil in, in mid-winter. Then you may find that the mineral API SN oils in a short time would not keep up with fully synthetics and some of the none branded synthetic oils would not keep up with the top branded makes after 9,000 miles.
