Hello all,
First time writer, long time reader. I own a 2013 Hyundai Santa Fe Sport Turbo. Because of the di engine and turbo, I keep my oci at the Severe Service interval of 3k vs the Normal schedule, 5k miles. I also use conventional 5W-30 Quaker State Advanced Durability API SN/GF-5. QS is recommended by Hyundai. Oil filters used, Purolator L14459 and OEM. I drive 35 miles per day and the city/hwy split is 50%. Sunny S. Florida, normal driver (not overly aggressive but not a granny either). As others have shared, Hyundai does not recommend synthetic for this vehicle and the oil requirements are not very stringent, API SM/ILSAC GF-4. You cannot beat QS for $14/jug @ Walmart btw.
I will not use synthetic since it is not recommended in the owners manual. My question, without getting a UOA is, can i extend my oci to 4k miles since conventional oils have gotten so much better in recent decades or is 3k my limit based on the engine type plus the turbo?
