Engine oil Mobil or OEM Mazda

I went with Mobil 1 5w-30 ESP. I read around the Bob is the Oil guy and that is what I came up with what I would best for WRX that will be tuned with an intake (My opinion). I am sure there are other good options.

Other vehicles, I ruin normal Mobil 1 until about 80-100K miles and switch to high mileage. Put over 200K on a '04 Civic Si on all Mobil 1 and oil analysis came back great every time.

I used the mobil synth high mileage 5w-30 for years in a 2001 accord lx 4cyl with 200k thru 274k miles when i sold it. Changed it about every 4k

My Tiguan and Passat all function perfectly with Mobil1 5W40, and I have used this oil for 15 years.

I found a really good deal on M1 ESP 0w30, about half the price of the LM. ESP is a good choice for modern DI motors for it's low volatility base stock, less oil vapor in your intake and better for cats. ESP is as good as it gets imo.

If you’re going from 15W-40 to 10W-40 the viscosity is the same. If you tekan a lot, suggest you try out something from Mobil, Penrite or Motul . They’re expensive for a reason.

Mobil 1 FS X2 5W-50 + BG oil additives because of higher mileage (259k km), been running good for the past 3.5 months, previous owner used some Castrol 5W-30, so i wanted a change and test oil consumption.

I've used a bunch of different oils including Castrol Edge, Amsoil, Valvoline, Mobil 1, and Liqui Moly. All Euro spec. All 5W-40.

I was trying different oils because our Tiguan burns oil, and I wanted to see if any particular brand would burn less.

So far, Mobil 1 Euro 5W-40 burns about half a liter every 1000 miles, while all the others burned about 800 mL. So I'm sticking with that oil for now.

I put Mobile1 0w-40 in mine, even though it's not vw certified

I'm not a fan of Mobil 1. I have noticed my car burns only on Mobil 1.
