    Synthetic technology oil

    Right I used to wonder what exactly "Synthetic Technology" on a bottle of engine oil meant. I have used Total Quartz 5W-30 Future for the Puma in the past. Label wise it meets all of the specifications and it has Synthetic Technology emblazoned on the bottle. A little research has thrown up this from the ELF lubricants site. And as a picture is worth a 1000 words etc etc
    Benefits of Synthetic Oil? - Advice / ELF
    Have a look at the illustration. Synthetic Technology is a step up from semi synthetic but it is still refined mineral oil with some fancy molecules thrown into the mix.
    There is no precise definition of semi synthetic oil or indeed synthetic technology oil. Each manufacturer has it's own definition and so long as the base mineral has been tweeked it can qualify. In Europe synthetic oil has to be 100% synthetic so you are safe enough there. However due to a judge in America being bamboozled with technical info he didn't under stand (by Castrol it seems) some of the other categories can qualify as "synthetic" in the USA because they have been tweeked and synthetic additives added to them.
    So if you want the full benefit of synthetic oil, especially on start ups, make sure it says FULLY SYNTHETIC or 100% Synthetic on the label. .
    I am not saying that the other categories are no good. They may meet all of the LR/JLR specifications but they will not deliver the pros of "Fully Synthetic" oil.

    For all intents and purposes Group III oils (synthetic technology, although most blenders will call them synthetic) are comparable in performance to PAO's (Group IV) except at very low temps.

    Don't sweat the base oils, it's the specs the oil meets and exceeds that are important.

    x2 what Rick said. Group III base oils are normally refined that much that they are very close to a full group IV POA base. Theres a good explaination of the base oil classes here:
