All Hyundai engines made in the Alabama factory come with synthetic fill. I know this for a fact because I toured it last year.

To all others...please keep this thread decent. I don't want this to turn into another conventional-vs.-synthetic argument and if it gets out of hand, I will not hesitate to come down hard. Keep it pleasant and you've got nothing to worry about.

Thanks for the comments guys much appreciated!

Not sure of what the difference is in the cost but is there a difference in the longevity of the synthetic over the dino? They recommend 3000miles for the dino however I am under the impression that the change period on the synthetic is some what longer?

Thanks

When I made the switch from dino to full synthetic, I did some tests on how long to go in between changes. I've always believed that 3,000 miles is much too soon to be changing out the oil and so I decided to try out the 7,500 mile interval. By the time I hit 6,800 miles, the car wasn't performing well, had troubles starting and was returning very poor mileage. I chickened out and changed the oil right away and all the problems went away with it. I now change the oil and filter every 5,000 miles using Mobil1 10W30 (per the manual for my area's climate) and a genuine Hyundai oil filter.

I switched at 50,000 miles and I'm now at 140,500 and have had no ill effects from it.

??? Now that's strange. Any thoughts on cause?

Not sure even to this day. I always figured it had to do with the oil being dirty but it may have had nothing to do with it. Regardless, it hasn't happened since.
