It could be, but I wouldn't do it if it is contrary to a manufacturers recommendation.
Use only SAE 5w30.
SAE 5W30 or 10W30 I would recommend the SAE 5w30 synthetic blend.
SAE 10w30 is a good all around choice. Possibly 5w30 in extremely cold climates.
No it is not. The correct weight oil for your car is SAE 5w30.
SAE 5w30 weight unless the engine is very high mileage which in that case use SAE 10w30.
Yes, if you live in an area where it never freezes. Otherwise use SAE 5w30.
Depends on the year which you fail to list. 2003-2012 requires SAE 5w20. 1998-2002 use SAE 5w30. Prior to 1998 use SAE 10w30.
SAE 10w30.
SAE 10w30 is better for lower temp and SAE 20w40 is the opposite better hotter temps.Thanks
Hyundai recommends that you use: SAE 10w30 above −9 degrees F SAE 20w50 above 32 degrees F SAE 5w30 below 95 degrees F If it were my car I would use SAE 5w30 year round and you are well protected. Also use a quality name brand filter such as Purolator, Bosch, or Wix.
SAE 10w30
SAE 5w30.
