I recently switched from TPT to Castrol Edge 0W-20 Euro which has the same certification (LL17Fe+). But now I'm due for another change and the Castrol is getting to be hard to find. I have an extra liter of TPT LL17Fe+ the I was keeping as a spare when the car was under warranty, and about 5qts of Castrol left over from the last change when I switched. If I mix them it's just enough oil for the job.
I don't expect there would be any issues mixing these oils since they both meet the same spec, but I wanted to see if anyone here agreed or disagreed. I've looked around for older threads addressing this, but there is usually a lack of consensus on mixing across brands.
The application is a 2016 X1, 80,000 Miles, no mods, in a hot climate (Houston TX). I know based on older threads that other oils are recommended for the B48, but I have the oil so I figured I should use it if doing so is safe.
