Engine oil Mobil or Lucas

Mobil 1 high mileage 5w30

But personally i like Mobil 1 brand

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. Used to be a valvoline guy but my motor blew up lol. Dont think brand had anything to do with it, just felt like shaking things up.

I was running it in a VR6 engine, and couldn't believe how much extra chain and lifter noise there was. I put up with it for a couple weeks, thinking it might get better but it didn't, so I switched to Castrol Edge 5w-40 and noticed the difference immediately. Noise means wear, so I feel comfortable staying away from M1 for my VR6 engines.
