Engine oil OEM Mazda or OEM Volkswagen

Could be weather related. I'm in Canada and we have weather from -35C to +35C, so Mazda recommends oil changes every 8000km instead of 12,000km.

I use original Mazda oil and Nipparts for the filters. I live in Europe and I buy these for 80€ / 85$.

For [Naturally-Aspirated Skyactiv engines](https://en.wikipedia.org/wiki/SkyActiv), it is highly recommended that you use Mazda's own(Idemitsu) high molly GF-5 0w-20. [Arguably it is one of the best oil for skyactiv engines]

I ran this exact oil in my late B5.5 1.8T, and it worked great, until some lady blew a stop sign, t-boning me and totaling my car. But it wasn't the fault of the oil, lol.

After reading several posts I got the Mazda Molly and Personally really like it! With the Molly it seems to run much quieter not such a heavy tick and just overall feels better’

I run 5w-40 in everything. Mazda Skyactiv, Toyota 3UR, Honda J35. They all like it and run quiet.

I bought a Mazda CX-5 dealer test car with 300 Km's on it back in 2015 when I moved up to Osaka. I drive a LOT and was getting the oil changed roughly every 5000 km's per Mazda's recommendation.

Just keep the right viscosity oil in it and monitor the oil temp. You might be able to read oil temp from you ECU through the obd port. 120-130C is very ok with good synthetic oil.

I blew up a VW polo with the wrong oil and high oil temps.

Wife has a 2015 jetta with the 1.8t and burns 1L every 500 -700 miles. My 2016 a3 burns relatively nothing but maybe half a liter every oil change interval and has same engine.

After reading this thread I decided to check the paperwork on my oil change that I got from a dealer last week. All it says is 6 G-E60-020-1B-DSP ENG. OIL Net 7.80 Total 46.80 which I assume means the "6" is the quantity. As far as I can tell, that part number equals VW 508.00 Spec oil. My car is a 2019 1.8L and the label under the hood clearly says 502 or 504 oil is required.
