Engine oil Mobil or OEM Mazda

Ive always used Mobil1 oil and filter and have 130k miles on my Veloster

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

Avoid Castrol. Use Mobil1 or LiquiMolly.

I'm using 5w40 and never had issues overheating in summer but im not doing half hour pulls. No oil consuption also. With 5w30 when driving hard it was eating a lot of oil.

Personally, I use Mobil1 oil in all my "regular" cars, and I often get a discount at O'Reilly when buying 5qts at a time. It's usually around $35 for a 5qt jug. That's pretty cheap.

Mobil 1 is one of the better, but you could use any 0w-20. I'd just say stick with a name brand and not something from a gas station.

mobil 1 high mileage synthetic has been good to me.

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).

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.

My 1.8T has just over 103k miles. I got it at 78k, and until about the 95k mile mark, I've been using M1 0W-40, then switched to M1 5w-40 Truck and Turbo-diesel, since I wanted peace of mind with its extra additives and protection. I figured since this oil is meant for high operating temps and high load in turbo-diesel engines, it would be just as good in my daily-driven and weekend-tracked 1.8T. I change my oil a few days before going to beat on it over the weekend, otherwise I'll change it every 3k to 5k miles. Also, I have had some valve noise (tapping of some sort), the whole time I've had the car. I'm guessing it's lifter noise. I'm not sure, but I was told to try a heavier weight to counteract it, hence the switch to the only decent 5W-40 sold on base. Still no difference in noise.
