Synthetic Oil

[ImUrOBGYN]

EXACTLY.

 

From memory, in Europe it was outlawed for oil manufactures to bottle and market their products as a full synthetic when it was truely syn-blend. Long story short here in the US we haven't come to those terms yet and we still get marketed full synthetics which are really not, to a worldwide standard.

 

That list that AJ provided includes TRUE synthetics among other smaller names like ELF which is now Pentosin, Torco and etc. that you can find if you look around.

 

And you wonder why those Amsoil tests show ungodly improvements over all other US, "Synthetics"... US synthetics aren't really synthetics

 

The easiest way to identify a full synthetic is if the oil was bottled and regulated by a European manufacturer. Usually, from my understanding, it is labelled on the bottles somewhere.. but you can also look online and do the research for yourself to find out what oils qualify by Europes synthetic standards.

 

Being a VW owner has made me aware of so many things, I can't help it.

Yes, I'm aware of this. It's a marking on the bottle to let you know. I cannot remember what it is, either. A buddy of mine will probably remember. I'll have to ask him next time I talk to him. I always forget it.

The bottle wont say whether they are true synthetics or not. They only have the API ratings on there.

Myth: Switching to synthetic for the first time on an older car can cause it to leak. Now if you switch to a thinner oil it can.

...

 

I thought it was a myth too, until my rear main seal started leaking within the first 1K miles of switching to synthetic. Do what you want though.
