Engine oil Mobil or Shell

My local AZ sells Mobil 1 10W-40 Racing 4T, Castrol 10W-40 and 20W-50 synthetic bike oil, and the best bargain of the bunch is Shell Rotella 5W-40 Synthetic T6, which is [rated JASO-MA and MA2](http://s7d9.scene7.com/is/content/GenuinePartsCompany/1843126pdf) (although claimed to meet the spec by Shell, it's apparently not officially certified by JASO).

Shell Rotella T. The normal type NOT the synthetic. It's a diesel oil you can use with gasoline engines. It's got all the good stuff you need.

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.

I use Mobil1 5W-30 in my R53. Checked with my dealer + that's what they use also. Served my car + me well for 135k miles so far.

Rotella T6 is very popular for turbo Subarus. It's 5w-40, which has some advantages. It's cheap at $20/gallon.

I've been very happy with Mobil 1 0W-40 EP, which I've used for many years in BMWs

For quality and availability, it's hard to beat M1 0W-40.

I bought 5 qrts Mobile 1 Edge synthetic 0W20 on sale with a filter from Advanced Auto for $40, took the oil and filter to the Honda Dealer, and they changed my oil for $15 labor plus tax and fees, total $18. So this brought total cost to $58 for synthetic oil change.

the only oil you'll find at Walmart that's approved is mobil 1 ow40.
