Engine oil Mobil or Motorcraft

Honestly, as long as you're changing your oil regularly and not putting Autozone branded oil in, it doesn't matter that much. I like Mobile 1 for NA cars.

I did an oil change last week at 5800 miles and used Mobil1 0W40 VW spec .

Truth, Its a much debated topic. Local testing has shown M1 0W40 to hold up the best.

I use 502/505 Mobil-1 0W-40 in my 2012 VW 2.0T, and my 2010 Audi 3.0T. I change every 3000 miles.

Mobil 1 Turbo Diesel Truck 5w40 has a more stout additive package and has lower sulphated ash which means less intake valve buildup

Use good oil, Liqui-Moly 5W-40, or Mobil 1 0W-40 "European Car Formula".

I use extended performance full synthetic - mobil 1. No problems so far.

Currently running mobil 1 MXT4 in my 2002 vstrom 1000. Holy fuck is it overpriced, but it's cheap insurance. Zero oil consumption despite cruising the highways at 140-150 Kph, @6000rpm.

No oil consumption within a 10k kms interval. So far so good Driven hard for my first 5000 Km's then dumped the factory oil. Been using Mobil 1 0w40 as I have in my past two GTI's. Drove it hard and haven't let off since.

I've been using Mobil 1 5W30 since I bought this car. My car has been tuned to my K04 and fuel limits for years and it's heavily abused daily. At 60K I'm still rocking 180psi compression, no turbo issues or VVT issues. As long as you change your oil regularly you should be fine, just stick to synthetics.
