tl;dr: Does it make any worthwhile difference to put European oil in a Korean car (Hyundai), or would any other synthetic work just as well?

My Vehicle Info

2008 Hyundai Accent, GLS 4-Door, SEDAN 4-DR, 1.6L L4 DOHC 16V, odo. 155,000 miles (Canadian car, so reads 250,000 km)

  • Is Terraclean necessary at all? This article seems to say no:

If your vehicle is healthy and shows no signs of excessive oil consumption, this treatment is unnecessary. Use quality fuel, change oil and other fluids as recommended and your engine will last hundreds of thousands of kilometres without assistance from such products. https://www.theglobeandmail.com/globe-drive/culture/commuting/is-my-garage-taking-me-to-the-cleaners/article14440034/

  • FWIW The Hyundai USA service schedules say 3000m oil change for "severe" driving conditions and 7500 for "normal". The Hyundai international website gives a 10,000m oil "normal" change interval and 6,500 in countries with average summer temperatures over 40C (e.g. the Middle East) or driving at speeds over 100mph, neither of which seems likely in Canada. So take your pick!
