Not sure quite what you mean ? Those are the only Synthetic Oils i could get in GTA stores.
That is exactly what the Big Oil industry is counting on in order to get you to buy their, "synthetic oils", i.e. that you're not sure what a true synthetic oil is. Don't feel bad and I'm not picking on you, but most consumers don't know and again that is what the greedy Big Oil industry is counting on. Unfortunately, consumers lacking in information on this topic buy their, "synthetic oils", in droves. I'm an independent AMSOIL synthetic lubricants Dealer of many years experience, so I'll explain the situation for you. So you can understand this topic, unfortunately, the answer is not short so bear with me.
You can Google this and find a many articles about this topic. Years back, Castrol introduced their Syntec, (tm), "synthetic oil", and it had a considerably lower price than other synthetic oils on the market. The folks at Exxon/Mobil wondered what was going on, checked into this oil and discovered that it wasn't really a synthetic oil in the traditional sense of the term, which is a man-made, vastly superior performing motor oil formulated molecule by molecule in a laboratory. This greatly differs from petroleum crude oils pumped from the ground that have random sized molecules, (some small, some large), that comparatively don't protect very well in high and low temperatures your engine experiences. Traditional synthetic oils have molecules that are all the same size so they are very resistant to evaporation/burn off at high temperatures and very resistant to congealing/thickening at low temperatures, providing outstanding protection for engines. It's a beast of a motor oil that provides unmatched protection for your engine! Petroleum crude oils also have a host of naturally occurring contaminants in them such as waxes, sulfurs, asphalts, napthenes, benzynes, etc., that have no beneficial lubricating qualities for the motor oil. They are
contaminants. Most of it is removed during the refining process, but not all and an unopened bottle of petroleum oil still has contaminants present in the oil that negatively affect the performance of the motor oil.
So, the folks at Exxon/Mobil closely looked at this Syntec, (tm), motor oil and discovered that what Castrol was doing was formulating a motor oil using a petroleum crude oil base stock but subjecting it to a higher degree of refining, which yes does create a better oil than a bottle of traditional petroleum motor oil, but this process departs greatly from what a synthetic oil has traditionally been and all the advantages a synthetic motor traditionally provides. Castrol's stance was that since they were using so many man-made processes to manufacture this oil that it therefore means it's a, "synthetic oil"! Exxon/Mobil cried foul, (I agree!), and took Castrol to court. Apparently they didn't present their case very well, as the court sided with Castrol and that yes this oil formulated from petroleum crude oils pumped from the ground could be called a, "synthetic oil". This new form of, "synthetic oil" is known as a Group III synthetic oil. The superior performing, traditionally defined synthetic oils are known as Group IV and Group V synthetic oils. In Germany, I have read that it is illegal for an oil company to refer to a refined from petroleum crude oil Group III oil as a, "synthetic oil". Kudos to Germany! :thumbsup:
Group III, "synthetic oils", cost less to manufacture than Group IV or Group V synthetic oils, so if a Big Oil company can manufacture an oil for a lower price and still call it a, "synthetic oil", while still charging a higher retail price for this, "synthetic oil", what do you think they are likely to do? Right.
Personally, I find this deceptive and unethical at best, to refer to an oil refined from petroleum crude oil as, "synthetic oil". But apparently it's, "okay", to deceive the consumer. :thumbdown:
You can contact these Big Oil companies and ask them if their, "synthetic oils", are a Group III or a Group IV oil, however I sincerely doubt they are going to tell you and give the standard canned response, "That is proprietary information". I've tried and that's the answer I get every time.
So how is the consumer to know which synthetic oils are Group III, Group IV or Group V? Petroleum motor oils typically have much lower flash points and pour points not as low as Group IV and Group V synthetic motor oils and this provides the big clue in uncovering a Group III, "synthetic oil". You can find this information in the Product Data Sheet of any oil which is usually, (although not always), available at a given oil companies website and compare the data from different brands to AMSOIL Signature Series motor oils. You'll be surprised with what you learn. :thumbsup:

I have done this research and in my opinion the vast majority of, "synthetic oils", on the market today are now merely refined from petroleum crude oil Group III, "synthetic oils". Not a bargain in my opinion.
