There was a dude on YouTube that did a test. Mobil 1 performed the best, followed very closely by Amazon basics
Man, just changed out the oil in my 2000 Crown Victoria Police interceptor yesterday with this. I HAVE USED THIS VERY OIL for close to 20 years. My shit runs as good as it has since I first drove it out of the Orange count sheriff's dept, Parole dept. auction lot. Never use anything else.
When it comes to brands most good brands work fine like Mobil 1, Castrol, Valvoline and so on. All these oils even including the cheaper amazon brand oils have been tested by the American petroleum institute and they have a stamp on every bottle.
Since then, I've changed my oil to a low SAPS VW 504 Mobil 1 5w30 ESP X3 which according to lubrizol has superior resistance to deposit and sludge formation. At this point, I've got consumption down to around 1qt/1400 mi which is a great improvement from where it was before. Hoping for further improvements with time but pleased with progress.
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’m slowly switching to Mobil1 since I started doing oil analysis.
It has no sodium and therefore a good way to see if there is a coolant leak.
I've used Mobil 1 in my 2011 Mazda Speed3 for 8 years. My 2019 Bullitt gets Mobil 1 as well. Mobil 1 is reasonably priced and meets the spec required by both cars.
Mobil 1. I've used it in all of my cars. Two of my mustangs lasted until 240k before needing a rebuild.
I used mobile one 0w40 but burned oil so I filled it up again idk might be cause of the heat or of course the motor which would be normal, but I usually aim at chaning the oil every 8k or half miles on my 2.0t TFSI engine and now I'm using 5w40 motul for my up coming oil change
I ran M-1 15w50 for 10k miles or so, and my car ran 10 degrees hotter on average than with any other oil I've used. Throttle response also felt sluggish.
