[speedminded]

i used royal purple in my 97 altima... burned. used mobil 1.. perfect.

mobil 1 fully synthetic ftw

There is no Mobil 1 in the United States that is fully synthetic. Actually, I don't think they make it any where in the world now. They may still offer a true synthetic in Europe but I doubt it.

You're paying for a 100% PAO based Group IV oil yet Mobil 1 does not have a 100% synthetic oil. It is all a Group III conventional oil mix despite saying "fully synthetic". When they quit producing synthetic oil in the US nearly a decade ago they failed to mention it to their customers or adjust their prices accordingly. Their price has continued to go up even though all Mobil 1 is refined crude base oil, not synthetic.

I WAS their number 1 fan until Mobil 1 jumped on the band wagon of scamming the public.

*Update*

In the late 1990s, Castrol started selling an oil made from Group III base oil and called it SynTec Full Synthetic. Mobil sued Castrol, asserting that this oil was not synthetic, but simply a highly refined petroleum oil, and therefore it was false advertising to call it synthetic. In 1999, Mobil lost their lawsuit. It was decided that the word "synthetic" was a marketing term and referred to properties, not to production methods or ingredients. Castrol continues to make SynTec out of Group III base oils, that is highly purified mineral oil with most all of the cockroach bits removed.

Shortly after Mobil lost their lawsuit, most oil companies started reformulating their synthetic oils to use Group III base stocks instead of PAOs or diester stocks as their primary component. Most of the "synthetic oil" you can buy today is actually mostly made of this highly-distilled and purified dino-juice called Group III oil. Group III base oils cost about half as much as the synthetics. By using a blend of mostly Group III oils and a smaller amount of "true" synthetics, the oil companies can produce a product that has nearly the same properties as the "true" synthetics, and nearly the same cost as the Group III oil. The much more expensive traditional synthetics are now available in their pure forms only in more expensive and harder to obtain oils.
