I thought the last time I checked prices at WallyWorld Syntec, Plat, and M1 were priced the same.

I agree.Mobil-1 is over priced.All synthetic are great if you change both oil and filter when needed.I'm choosing Castrol Syntec 5W20 and staying with it for the life of my 2006 Jeep.I don't see how one would perform better than the other in the long run.Joe
what about amsoil XL series line. it is a hydrocracked group III oil and they call it a full synthetic oil. I dont hear people bash on this like they do on castrol syntec. this oil is priced a lil higher than syntec. so I guess price isnt the motivating factor to bash on castrol.

Castrol simply made a big mess saying hydrocracked/dewaxed is synthetic when previously synthetic was Group IV/Group V. Castrol Syntec is NOT Castrol Syntec...ie. GC vs Syntec 10w-30. Maybe the labels should be more open/truthful. "Castrol Group III with additional additives" or "Mobil 1 Group IV with regular additives."
If you remember correctly, Castrol won that court battle. Castrol won on the grounds that the base molecular structure was changed from it's original form to be more efficient. That sentence defines synthetic oil. Any oil changed at it's base by man. Had it not been for Castrol, the synthetic oil world would be filled with court battles defining what % of PAO defines synthetic(a la Euro). 10%PAO with 90% group III? 20/80?? Castrol's court battle helped to keep a lot of mumbo-jumbo out of our legal system, not to mention allow some fine group III synthetic oils to step up.
Group III is synthetic by it's very nature that no matter how much you refine oil out of the ground, it will never ever be even close to what group III is. Oil needs to be changed at it's base molecular structure to achieve group III statistics.
My apologies for repeating myself but, it was necessary to get the point across to those who may not have understood.

First sentence is not true. Without petroleum base stock they would not have the needed components to create the molecules that form the basis of group III oil.
Nothing wrong with group III base oil so long as the finished produce it well formulated. The real question is knowing what you are buying. For that, just assume all oils labeled synthetic are group III unless the company is willing to state they use group IV or group V as the majority base oil. I think most that do would be willing to say so. It's to their advantage.

Reply:
1) It wasn't a court case.
2) If Group III is truly "synthetic" why wasn't GC (Syntec 0w-30 MADE IN GERMANY) Group III? In Europe, Group III is NOT Synthetic!
3) As I stated earlier Group II+ and Group IIIs can all give great performance depending on adds. Group III is cheaper to produce that Group IV/V, yet Castrol sells Group III at a premium price.

uconn1150---That's the issue. We cannot say that syntec is overpriced because we have no idea of the additive package.
No i have not. Are they impressive?
If you can find group III oil coming out the ground naturally I will give you the title to my car. Group III is natural crude oil that is severely changed. It is synthetic, altered by man. That is what makes it synthetic. The only reason why Europe does not allow it to be called synthetic is because the base ingredient before the oil is changed is indeed dyno oil. Their reasoning makes about as much sense as why they are paying $6.50 a gallon for fuel. None.
In my original post Castrol stated in their reply to me that the their Syntec synthetic motor oil starts out with a synthetic base stock and not a petroleum base stock.If this is true than would that oil be considered a 100% synthetic motor oil?
I'm not trying to start a war but I'm trying to understand if it's worth buying.Thanks Joe

what if its EOP?
The base stock Castrol starts out with is indeed synthetic. It is basically dino oil that has been genetically altered to be anything but dino oil but, certainly not quite group IV either. Syntec is fantastic stuff. I am a big fan of the 5w-50 in my '86 Porsche 911. I mostly run Shell's Rotella T synthetic 5w-40 which is also a group III oil. Shell's base stock just so happens to be the same base stock Ferrari's F1 team uses as well.
Group III is great stuff. Do not let anyone tell you it is dino oil. It is certainly not dino oil, and it certainly is not group IV but, it performs just as well as any group IV. Buy it, use it, enjoy it.
