Oil filter Castrol or STP

I did Castrol Edge Euro Car 5W-40 with a Hengst oil filter, but if you want to spend a little extra most people recommend LiquidMoly

I used the Castrol once, and have been buying the assembled kit from ECS ever since. At 73K miles, now, and change it every 7-8K.

Castrol Edge 0w 20 with the Dexos1 and an STP gold filter done at 2k.

7500 miles religiously, including filter every time. Full synthetic 5-30 Castrol.

I buy Castrol edge and Mazda oil filter off Amazon.

Personally, I just use whatever is cheapest, as long as it is rated decently by the API. The way I see it, oil is really just oil. It's slick, it lubricates, it has whatever weight and viscosity it says on the bottle. The API makes sure it reaches those standards along with any claims on the bottle, so I'm comfortable saving money there. I've never had any issues in my many tens of thousands of miles of ownership and there's no sludge buildup or any worrying deposits inside the motor that I've seen when I've worked on it.

a 5qt Castrol edge 0w-20 container is $19. + $8 for a filter .. $30 every 5K miles is cheap imo..

I use factory filters and 0w40 Castrol (German one) when it’s on sale for $4.99 a qt. I too have 100k on my 2015 gsw 5MT and runs great I been using that oil since new.

Put some normal oil and an STP filter in it. Got it all back together, runs great. Ran around the block, noticed the oil light flashed when over 2500 RPM . Back in the drive way, let it cool down. This morning, put motor flush in, idle it for 5 minutes per instructions, and drained the oil and changed the filter. Looking at the filter, it seems collapsed. It doesn't seem horribly clogged - there is a bit of silt in the crevices, but that was expected. Is it just because of the cheap filter?

When I first purchased my VW, I could drive it how ever far in whatever temperature and wouldn't get any beeps or blinks. I brought it to a friend to do an oil change and he threw 5W30 in it with a STP oil filter. After that oil change, if the car was driven too long the light would blink and the ding would chime. If you revved to about 2300~ RPM, the noises and blinking would stop. I guess that is a temporary fix, but all I did was change the oil to 10W30 and haven't gotten any noises yet. I guess 5W30 is too thin and can't build up enough oil pressure? I'm not too sure.
