Good evening! I just purchased a 2017 Tucson with a 1.6 turbo engine.
The oil specs in the Tucson owner's manual states ACEA A5 is recommended. However there is a note that states "If ACEA A5 is not available in your country, you are able to use ILSAC GF-3 (or above) or ACEA A3 (or above)". Oils meeting the A5 spec seem limited to fewer choices than GF-5 oils. Which oils are better? A3/A5 oils or GF-5 oils. Should I hunt for A5 or go with a more easily available GF-5 synthetic?
