Delo 400 multigrade on a 3,333 mile interval (basically three times per 10,000 miles.)

In a few newer vehicles around here I stray from that. My pickup is a Ford with a 4.6 V8 and due to several valid reasons, requires lighter oil. I use Mobil 5000 and change it every 3,333.

My wifes Mini Cooper requires 5W30 synthetic, so it gets Mobil One on a 10,000 mile schedule.

Have a great day,
