Engine oil Mobil or OEM Subaru

Mobil 1 5w-50 for the last few years.

I always used Mobil1 High Milage oil in my old truck before I sold it.

I run Mobil 1 in my bikes.

Mobil 1 Definitely. 0W20 in my 2023 Sonata Limited. 5W30 in my 2014 Sonata Limited.

I do my own oil changes. dexos is pretty much a quality certification standard and I use Mobil 1 Fully synthetic 0w-20. I did my first change at 1,5k then at 5k and will do one at 10k. I always replace the filter and I have a magnetic drain plug to collect shavings that may pass through the filter in case it ever is compromised.

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

My '15 Forester will burn a quart of oil every 1000 miles if I run 0w20.

I switched to 5w30 and it's all good for 5000 miles

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.

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.
