Unless shortcuts are taken on quality, or the pricing gets out of hand, I think that they will stay a top oil around here.
If and when I switch to HPL, I'll get 5w40 Euro.

I have yet to see EC30 remove any kind of varnish as evidenced by pics shown here.

I had to look up what vsot stands for. It looks like they still might sell it?

Two things can be true. One can be truly interested in motor oil, while also recognizing that oils here trend every few years on a cycle.
Great oil but overkill and too costly for my old junks.
HPL Euro VII PCMO 5w-30 on 14 Toyota Venza 2GR-FE
HPL PCEO 5w30 in my C5.
I’m waiting for Project Farm to test it. Until then it’s just another pretty face. 
I had 2 previous 5k OCI with HPL EC 30 in a 1 to 5 ratio with high mileage full synthetic 5W-30.
Then I had the valve cover gasket leak, where my mechanic showed me the significant orange/brown varnish right under the valve cover.
So maybe it was even worse before that and HPL EC 30 cleaned it a little, or perhaps HPL EC 30 didn't clean the varnish at all.
It would be interesting to do four 5k OCI with Valvoline R&P, and then to remove the valve cover to see if the varnish is gone.

Do you think the EC30 contributed to the leak? I always wondered about that product and others like VRP cleaning out deposits and causing leaks
I had a small doubt about that. Van had a new valve cover gasket installed 2 years earlier (but with an aftermarket gasket).
When this 2 year old aftermarket valve cover gasket started leaking, it was an expensive job, as oil leaked into the coil packs and hosed them, so with the coil pack replacements too, was like $800 total including parts and labor. I attributed it to the aftermarket valve cover gaskets, but still, it's unknown if any of the cleaning I was doing caused an $800 repair. To be fair, I also did some solvent based engine flushes as well before each of those 2 oil changes.
As exciting as cleaning out the engine to "like new" cleanliness sounds, it has the potential to do a lot of financial harm if it affects your gaskets or seals. In retrospect, I'm thinking it's better to just use any high mileage full synthetic oil of your choice with a reasonable OCI (like 5k miles), and not do any cleaning. With an older vehicle, treating the oil seals with a high mileage full synthetic oil to prevent leaks is more important in my opinion, as oil leaks cost money to fix, and you don't want the car leaving oil stains in your garage or on your cement in your driveway.
