Oil filter OEM Mazda or OEM Volkswagen

I use OEM Mazda filter. Synthetic oil, Kirkland brand or Castrol since i think thats who makes the Mazda oil.

I have a 2013 Jetta that calls for 5W-40. I only use oil filters purchased directly from Volkswagen, and I only use Castrol oil. I've had positive results doing this

I am not sure if you can and have a place to do it on your own but I bought oil vacuum pump couple years ago and changing oils myself since then. I have a Volkswagen and oil filter easily accessible from the top.

I personally do an old and filter every 6-7000 km. I do it so frequently because, 1) I do it myself, so cost is down and I make sure the job is done right. 2) the sky active engines are known for carbon buildup, so more frequent oil changes should help. 3) Longevity, I want to see 300,000 or more on the dash one day.

People like me on the other hand are going for synthetic oil and Mazda OEM filters but still need to get an oil change at 5000 miles.

An oil change with decent full synthetic is 30-40$ for 5 quarts + OEM filter for another 5-10$. It's relatively cheap to do every 6-8 months to know it always has decent oil, and no problems should arise.

I'd go with the OEM Mazda Oil Filters but any high quality synthetic 0w20 will work fine.

VW Touareg V6 roughly $600 at an independent euro mechanic for regular service

Das original VW öl bekommst du für 10€/l auf ebay und den ölfilter wahrscheinlich für um die 10€.

I just changed the oil on my TDI at 15,000 miles and when I pulled the engine cover it looked factory fresh under the cover. Meaning there was no evidence that the dealer even made an attempt to change the cartridge filter. I was very, very careful not to spill oil on the engine components but still managed to get oil on the white mesh heat shield next to the filter housing. When I removed the cartridge filter it looked extremely dirty and gunky.
