Engine oil Mobil or PETRONAS

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.

Mobil 1, my 05 GT with 150k miles on it getting cams a few weeks ago looks clean inside. I've had the car since 70k and Mobil is all I run in it.

LiquiMoly is fine. I used 0w40 Mobil 1 as I do in every single one of my cars for the last decade and it’s absolutely fine.

Not sure if my opinion matters, but I use the Toyota version of the Mobil1 0W-16. Runs great.

Change the oil again and use Mobil 1 full synthetic and make sure it says V-TWIN on the label.

I’ve been using Mobile 1 since I’ve purchased my RAV4-brand new. Now at 160xxx miles with no oil burn. Runs like the day I bought it

I used mobil 0W30. Seems like they're one of the few that make it

Mobil1 and Castrol are all I’ve ever used on my 266k mile 09 rabbit. I replaced the valve cover in nov 21 and that engine was super clean inside. Still runs very well.

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.
