question about dino vs their grp III counterpart.

[aquariuscsm]

I'm wondering(and i'll use castrol as an example)is the only difference in a dino and their grp three counterpart,is that the grp three is only a "de-waxed/purified" version of it's dino? Reason i ask,i was looking at voa's of syntec,and someone said that the gtx and syntec oils look identical via voa. Hope this is all legible,i'm posting this from my phone,and the caps and numbers buttons won't work on certain websites for some weird reason.

From what I've read hydrocracking conventional basestocks re-aligns the molecule making it almost equal to a true synthetic.
I think that group 3 oils have proven themselves and the operational differences are pretty much equal.
Unless the application is extremely hard on oil I really believe the line between group 3 vs group 4/5 is blurred and no longer an issue.
Again,depends on the application. I don't think an engine will know the difference when driven within posted speed limits.
Now maybe driving the autobahn,at wot for extended periods may deem the need for a true syn however here in NA we can't drive vehicles that hard.
Just my opinion

VOAs can not determine if an oil is synthetic or dino according to B_S.

I believe the extra refining of the Group 3 process makes sure all molecules are the same size and will perform uniformly.No "rogue" molucules to ruin the mix...

Do dinos and their grp three counterparts use the same add pack? Seems like it does looking at voa's.

I would say some might, but some definitely don't. Compare PYB to PP or PU, and you'll see substantial differences.
