Royal Purple VS OEM

[HyundaiGuy]

All of the BMW/Mini approved oils on the 2007 and newer models (with the turbo) are LL04 rated, and all are 5W30 except the Mobil 1 which is 0W40.

The 2000-2006 models (supercharged) specified 0W30 or 5W40 LL01 rated oil.

I have driven 500 miles since the oil change and peered down the valve cover and it looks much cleaner already. It looks pretty darn good, I just want "better." Also, I have noticed that the fan doesn't run nearly as long after a highway run. Could the engine actually be running cooler? No temp gauge, sorry.

Also, BMW/Mini have backed up a bit, they have recently changed the OCI from 15K miles to 10K.

Even without the turbo, no way would I do an extended OCI on this car. The cartridge oil filter insert is tiny- it looks like it belongs on a riding mower.

I don't understand how you can mix oils of 2 viscosities and expect to know exactly what the outcome would be.

Many oil companies say this is totally fine. Redline actually encourages it. I've talked to Motul and they also say it's okay to do. The VP of Renewable Lube told me you can do it.

It's not hard to do the math and approximate what the "new" viscosity will be.
