The problem with this oil is the price, $39 at Walmart for the 5 quart container. The Mobil 1 EP is good for 15,000 miles and costs around $25 without the rebates. Most people put on less than 15,000 miles a year so why pay the extra $14 dollars when the Mobil 1 EP will do the trick!
Dealerships and places that change oil also like low mileage intervals. It seems the core service of my dealership is oil changes. From there they can recommend or up sell other profitable services.'Big Oil' loves the old timers that do 3K oil changes like they are still in the 60's. It probably wasn't even needed then either. 7500 is ok, for a lot of people that might be once a year... but nobody should say that longer intervals can't be done or shouldn't be done.
I'd say if a high percent of your miles are highway the oil could hold up well for 20k miles, some engines with larger sumps like v8 and v6 probably better candidates than turbo 4s with smaller oil capacity.
Engine oil has functions apart from lubrication. Oil is used to help cool the engine, clean the engine and help reduce acid build up. Regardless what oil type or brand one uses oil change intervals must not exceed the vehicle manufactures requirements.
Direct injection engines may benefit from more frequent oil changes due to increased by products of combustion that these engines are known for. Using the very best synthetic oil does not permit one to exceed oil change limits under vehicle warranty.
If you have a high performance vehicle or hard worked vehicle then using synthetic oil may be of benefit and may even give one a warm fuzzy feeling but a lighter wallet. Just remember not to exceed oil change limit.

Thank you for contacting Hyundai Customer Care and providing us an opportunity to respond.
In regards to your query we have contacted our National Technical Department and are more than happy to advise the following:
The best practice is to use the same oil brand / type currently in the engine this will have the same additive pack. We recommend purchasing the oil directly off the dealership so it is the same.
However, if you are carrying out an oil change on the vehicle the oil must meet oil specifications listed below (or in the owners handbook) of a viscosity of 10w-30.
The decision between Synthetic, semi synthetic and mineral oil is not relevant as we do not publish or recommend either way. The oil must only meet the required specification. The fuels listed in your email are all ok with no issues.
If you have any other questions please don't hesitate to respond to this email.

Agreed. Regarding OEM filter read this post by Fram's Technical Director Motorking:I'd say if a high percent of your miles are highway the oil could hold up well for 20k miles, some engines with larger sumps like v8 and v6 probably better candidates than turbo 4s with smaller oil capacity.
IMO Hyundai and KIA in the dark ages with respect to their oil maintenance requirements, some have mentioned on here in oil filter discussions for example that the OEM filter is best for no other reason than it is the OEM filter, assuming that Hyundai puts a lot of thought into such things but I'm not so sure.
Their OCI intervals are designed mostly to protect their 10/100 warranty intersts in the US, was discussed some yrs back that Europe and other areas have different oci (longer) intervals.
Motorking said:Hyundai and Kia both are having oil pressure spiking issues. The Hyundai solution is to have Mann build what is nearly a racing filter in construction. Premium Guard filters can barely hold 200psi without blowing out the O ring so they issued a service bulliten saying they will supply the OES filter until they can redesign their filter for this application. We upped our burst strength on this filter PH9688 to 360psi from 240 due to this issue. Using "low cost region" filters on these engines may cost you an engine if you are not careful.
