I often ask myself what I would do if facing the types of dilemmas you guys do. At this point, I believe it would involve frequent oil changes, with a motor oil I had confidence in, but was economical in price.
It was surprising to read today, a link to an article, posted by an expert in the field, where he referred to a "Group III+" motor oil.
As someone who is big on base stocks, I would be interested in your thoughts, Dennis, on using Pennzoil Platinum Euro (GTL) vs using Motul (Group IV).
Do FT86 trackers really, really prefer esters?

It's pretty much accepted practice in the industry to refer to a base oil as "Group x+", even though technically no such group exists.
GTL's have been shown to match or beat PAO's in most categories, but esters are still considered the best. The problem with oils though is that you really don't know how much you're getting regardless of the base stocks used. If I added forced induction to an 86 and ran it on the track, I'd definitely want esters and higher levels of anti-wear additives though(Motul 300V/Red Line).
AZP Installs recently switched from 300V to non-ester based X-clean in their track car and I believe that oil is doing really well (not sure of any uoa's). I'm sure the higher HTHS and kinematic viscosity (compared to a GF5) will help, regardless of the base stocks. With Motul, unless you use one of their "Technosynthese" oils, you're probably getting Group IV and/or V.
This is a very good article on esters:

I think
most people will just bump up a viscosity grade of their favorite brand instead of switching to $12-$18 a quart ester oil. I'm surprised no one here seems to be running Group V vegetable oil:
