I buy a large drum of Smith and Allen full synthetic 5/30. I've used this for several years in in various cars belonging to my family. We gave our old Jazz to my son it's 12 years old and done in excess of 80,000 miles on this stuff. It also goes in my wifes Yaris, daughters Mini and her husbands Hyundai Tucson. I tend to use Mahle or Bosch oil filters. I also ran my previous BMW 320D on this (replaced by my current Jazz) That's still going with over 100,000miles on the clock.
