Way back there was a question about which brand of oil to use, and the answer is simple. It does not matter. Any top brand is equally excellent. Top conventional oil is very good. Synthetic oil is better at very cold temperatures as it thickens less in the cold, at very high temperatures because it thins less in the heat, and it oxidizes more slowly for longer oil life. I use syn in all my turbocharged cars (2 so far). Keep in mind that turbocharged diesels in trucks, ships, rail engines, etc., use conventional oil and have great results--the last ship's diesel engine I worked on had four 4' diameter turbochargers with 30 wt conventional oil in their own sumps, an no oil lubricated problems. Do use the quality and viscosity engine oil recommended in the owner's manual. Low viscosity oils such as 5W-20 and 0W-20 create less internal friction inside the engine for a sliver less drag and a bit better gas mileage, as well as being more suitable in frigid temperatures. The current top oil categories are ILSAC GF-6A and API Service Category SP. Those are upgraded every few years, and always buy the most current. They will be fully compatible with the older categories listed in older owner's manuals.
For filters, it's different. There is no industry standard for oil filters like there is for, say, GF-6A/SP 5W-30 engine oil. Each engine maker's oil filter is a secret. Aftermarket oil filter companies may reverse engineer the engine maker's filter and make one that matches or just pick one out of their catalog that seems to be close enough. During the warranty period I suggest sticking with the engine maker's filters. After the warranty any top brand of filter is likely just fine.
I do not know if there is any functional difference in the Mazda filters from different makers in different countries. I do know that during the engine warranty period any suitable Mazda filter fully satisfies the warranty requirements. I know of one Thai filter maker, HiFloFiltro, that makes very high quality filters, and I have good experiences with their motorcycle line. They also make the K&N motorcycle oil filters.
