I like using the very best European products available!
Avista uses their many own patents for recycling used oil. They sell different grades of recycled base oil to most manufacturers, and use it for their own brands too. It is by no means inferior. The most expensive oils are usually based on or made with recycled base oil. The first oil of the three in that post is a popular Avista brand, and totally matches Mitsubishi specifications for our cars.

SCT markets all sorts of stuff under Mannol, SCT and some other brands, and is often regarded as a particularly price-worthy source of aftermarket products.
As far as the Filtron filter goes, it is uses PFTE for the non-return valve, where just about all others simply use cheap rubber. Radial shaft seals (lip seals) are also PFTE, they would easily leak if made of rubber.
PFTE is much more expensive, but highly flexible and retains its properties, unlike rubber.
Such non-return valves will work with horizontally placed filters, where rubber won't work. The OP575 also has a bypass valve, the OEM filter doesn't.
Btw, the Mitsubishi ASX uses practically the same filter as our cars have, but includes a bypass valve. Its main purpose is not for bypassing a clogged filter, but for grossly reducing the time period on startup before oil pressure builds up behind the oil filter.
Filtron is one of the largest filter makers in Europe. You may have heared of them as Mann + Hummel, and Filtron being a top notch brand. They make OEM filters for just about every premium car maker.
