4.4i cranking for longer than usual...

Even with the hot climate my X is subjected to run in (TX and FL) I use the Mobil [1] 0-40 European Car oil. Iv'e seen the OBC outside temp showing over 120 deg F while towing a 6k lb trailer in stop and go hwy construction traffic many times (AC on Max too). With over 160k miles everything is OK (even OE timing chain guides). Can't understand those who run higher weight oils in these engines.

How long would you run the Mobil 1 oil in your X?

The prior owner had the dealer do changes according to the SII (Service Interval Indicator), so the X had BMW oil approx every 15k miles for the first 100k miles. I switched to the Mobil [1] 0-40 EuroCar oil when I bought it and I change it when the SII has 2 green bars still lit, around 7k miles on the oil.
