Is Castrol finally making a true synthetic??

We sell that stuff at my work for $8.49 a qt. Not sure of the exact specs yet, but we have carried Castrol Syntec for years (black rectangularish qt size bottle) and as far as I know, it is also fully synthetic. I believe the Castrol Edge has new additives in it to help with engine wear and performance.

Well, a few years back, there was a lawsuit between Mobil and Castrol...cause Syntec, according to Mobil, wasn't a true synthetic since base oils weren't 'synthesized' like PAOs. Syntec was using 'super refined' dino oil and Mobil at that time was using PAOs.

I heard that this new Castrol Edge oil has PAOs in it...but not sure how much...

Good to know. I prefer Mobil to Castrol, but they are pretty durn close in quality levels, as far as I am concerned. I know Mobil outperforms Castrol, but I have used both and don't notice any difference in my XJ. (Keep in mind that we talking about a Jeep 4.0 versus, say, a high performance sports car!)

Yeah, know what you mean...sometimes I think I can throw mud into the 4.0L, it'll just laugh and keep running...

Mobil 1 isn't true synthetic anymore. If you want real synthetic you have to go with amsoil or redline. If this new castrol is real synthetic then that's a plus, it gives us more choices.

Yeah,but it is GF-4 rated, so it is not good for our engines,unless you get an ZZDP( zinc dithiophosphate)additive for it.
