I would love it if the whole world moved away from fossil fuels and completely to renewable energy resources. Myself included. However, for many practical reasons I currently own a vehicle with an internal combustion engine, and when it needs an oil change I change the oil myself. So what oil do I buy? I buy Mobil1.

We exclusively use Mobil 1 (varying grades and viscosities) per the MFR spec and changing it at the MFR spec mileage (or time, during covid). Never any issues noted. 1985 BMW K100RS (122k miles), 2003 Boxster (177k miles), 2012 Acadia (98k miles), 2013 Jetta SEL (105k miles).
Pros: Never any issues noted, Reliable in multiple vehicles
Vehicle:
Volkswagen Jetta
The best oil to use is the RedLine full synthetic two-stroke Racing oil. Modern full synthetic two stroke oils are way better than older oils and work great.
Pros: works great, way better
Vehicle:
Saab
I have used the green stuff for my last 3 oil changes, not looking for leaks but at the same time will be easier to spot if something does decide to pop up.
Pros: easier to spot leaks
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.
Vehicle:
Mazda
Mileage: 5000 km
Part number for the oil: G055512A2 $14 (x2) O-ring: N90362001 $4 (x2) Paid ~$38 total Yeah my dealer is about 40 minutes away so I bought two in case I want to order oil in the future and do this again sometime...or if it leaks for some reason and I have to drain/refill, I just didn't want to drive back.
Pros: bought extra o-rings
Vehicle:
Volkswagen Jetta
Part number: G055512A2
i'll keep using the blue jugs....i love this stuff
Pros: love this stuff
Vehicle:
Volkswagen Golf
I used to use Mobil 1 (European formula) and was a good oil as well but when I switched to liqui moly the engine in that gti was running so much smoother so that’s why I only used liqui moly in my R as well
Pros: engine running much smoother
Vehicle:
Volkswagen Golf
5W-40 is better for the M54, IMO - try Fuchs Titan SuperSyn or Liqui Moly Leichtlauf.
Pros: better for the M54
Recently got my first oil change at 5K and used mobil 1 0w40. The engine is now louder as compared to what it originally was. Not sure if it is the oil being too thin? or perhaps the cold weather.
Cons: engine louder
Vehicle:
Volkswagen Jetta
Mileage: 5000 km
