[QUOTE="Creedence85, post: 177755, member: 4346"] Mobil 1 is full synthetic. Here are all the grades and versions sold in the US. [URL unfurl="true"]https://mobiloil.com/en/motor-oils/synthetic[/URL] Full synthetic just means all the base stock has to either derive from group III (conventional oil aka dino oil that's been hydrotreated) or group IV (synthetically derived). Semi synthetic or synthetic blend just means that there has to be some group III or group IV synthetic base stock in the mix, but it can be any percentage of synthetic blended with any percentage of conventional. I use Mobil 1 because it's a group IV synthetic. Group IV synthetics are superior to group III because synthetic base stock is molecularly uniform. The hydrotreated conventional base stock in group III is more molecularly uniform than group II (dino oil that's been chemically refined), but not as uniform as group IV. The problem I have with group III synthetics is I'm not sure what the difference is between a group III conventional oil and a group III synthetic oil beyond the additive package, since they're both hydrotreated. If I'm going to pay more for an oil, I like the idea of the oil itself actually being better, as well as the additives. [/QUOTE]
