Hi All.
I am in a unique position here.
My GF drives a 2004 Hyundai Getz 1.6. The oil that the OEM recommends to use is 10w40. She has, however, been driving the car with 20w50 for 1-2years now.
My Question is, should I go back to the recommended oil or should I keep using 20w50 now? I am just concerned that using 20w50 for such a long time may have changed the tollerances in the engine and if I now go back to 10w40 it will cause problems......?
Any help please as I am looking to do an oil service this weekend.
Kind regards,
