Hello! I have the following question about suitable engine oils for the Hyundai i10 as described above. Since I agreed with the dealer that I will supply the engine oil, I do not want to do anything wrong here. Since I do not want to get a problem with the warranty. Unfortunately the dealer was not necessarily able to help me or did not want it and also the dealer where I refer to the engine oil was not 100% sure. In the operating instructions of the vehicle is regarding the classification for Europe: API service SM or higher, ACEA A5 or higher I have already tried to read in and then you read various things. A5 should have an advantage when saving fuel but is at the cost of materials etc. On the next page of the BDA there is a recommended engine oil “Shell Helix Ultra ECT C2/C3 0W30” This has no A5 classification at all? Or is C2/C3 automatically higher than A5? With the A classifications there is nothing more than 5?! of the year of the car should be about 2018 / 2019. Exhaust gas class says the following: Euro 6d Tmp (EU)2018/1832DG – wrongly this would still be important. Would be happy if anyone could help me. Thank you in advance!
