So as I am eagerly awaiting the delivery of my PHEV, I took a look a the maintenance schedule and I was surprised to see oil changes at 6 month/8,000km intervals, identical to the intervals in the HEV. This seems a bit strange, considering that depending on your level of EV usage in the PHEV, you could be running the gas engine significantly less, and ostensibly need far fewer oil changes as a result. This was one of the things I considered when looking at the cost savings of a PHEV vs. HEV/Gas.

The reason I am a bit surprised, is that for the new car warranty, it states that your warranty could be void if there is "Damage or failure resulting from Negligence of proper maintenance as specified in the Owner’s Manual and this Service Passport.". So would that mean that I would need to get essentially oil changes at least twice a year just to maintain the warranty?

If the oil stays for long time, it's not good too afaik. So you can basically never use the engine but you may still need to change the engine oil.

I will change Oil like the shart at 8000kms , but by the way I get mustang Gt manuel 2000 that I don’t run in Winter , I change oil every 24 months, the car is now at 88,000 kms , and I never had some problem

Agreed, this is my 3rd PHEV and they are mostly all like that. It makes no sense to waste money and oil to change it after 8,000Km when you do a lot of EV riding.
The service interval should be "computed" according to you real usage and oil changes intervals.

Unfortunately, Hyundai seems to have set a "middle mark" range service interval at 8 000Km for an "average user".

The dealer even tried a sneaky move on me .... in the dash, you can adjust the service interval alert and the stealerhip rolled it down to 6 000Km prior to my delivery ... in an attemp to get me in the garage more often 🤑 !

I believe that 8000km applied for mineral (regular) oil
If you do full synthetic then interval could be 16000 km that what Toyota recommends for their hybrids

Exactly, synthetic oil should easily last a year and the RAV4 Prime has an oil change interval of 16k km and 1 year.

It just seems like such an environmental and financial waste to get two oil changes with synthetic a year if your gas engine only ran for 5,000 km, something that easily possible with a PHEV that has a 50km range, while doing 10 to 15 thousand km in electric.

I will ask when I pick up the car if only doing one oil change a year would count as voiding the warranty and reach out to Hyundai Canada to see if they could maybe adjust the language in the PHEV maitnence schedule to account for this!

The PHEV manual mentions each 8,000km or 6 months.
The "service interval" reminder alarm in your car is a custom number you can program with any setting you want....
look in "User setings" under the menu convinience.

It is set at the "stealership", mine tried to trick me by setting it to 6,000Km.

I bought the Hyundai Prepaind Maintenance for my PHEV and it is every 6 months or 6000km as per the maintenance contract. Even without the PPM it was told it is every 6 months or 6000km. That could be based on me being in Canada with our climate.

LOL, you can program it to 20,000, you'll save even more

, but seriously, I understand you, this is a personal choice (cost savings vs risks),
as Hyundai may give me some troubles down the road in the event of a warranty claim... I don't think its worth to stretch the oil services.

Assuming you ride 20,000km yr, I'll save a couple oil changes to cheat the manual in 5 yrs...
Over a 5 yrs period, stretching the oil changes will avoid a few oil changes in a 5 yr span.

Also, some other stuff is to be checked at the 8,000K increments and I'll hit the 6 months delay before the 12,000k anyway.

Ah ... good to know, but I will gladly believe the 6,000km when I see a written document from Hyundai stating the interval is 6,000km.
Up to now, aside from verbal stealership BS and dealer issued documents, I never saw a maintenance document with this 6,000Km.

The Canadian Owner manual is crystal clear : 8,000Km and IMO .... 8,000Km is already way too frequent and abusive.

Dealers make a lot of pesos with service, they try to upsell you tons of useless crap once they trap you in their garage.

I just re-looked at the prepaid maintenance and it is every 6 months or 8000km. I will never make the 8,000km as the 6 months will happen before. With the prepaid maintenance it is a fixed number of visits which work out to every 6 months. If you don't use the visits before the mileage or years run out you loose them so every 6 months for me.

How I see that so often oil change intervals with synthetic oil is just to make Hyundai service department extra profit, but you should follow scheduled intervals to keep your warranty.

For example I do with my VW 2.0 Turbo engine every 15,000 km or 12 months whichever comes first as per schedule with synthetic oil ( Ontario, Canada ).

This VW ICE runs approx. 4 times more in those 15,000 km than Hyundai PHEV ICE in his 8,000 km because PHEV use electric motor at least half of those 8,000 km.

Technically you can change oil once a year or every 15,000 km easy, but on your own risk .

I am not sure yet how often I will do oil change on my preordered Tucson PHEV in the future !

So after picking up my PHEV, I asked about the Oil Change intervals, and they said that oil still goes bad after a while even if you are mostly using the EV motor, which is technically true but not within 6 months! In any case, they said that I could push oil changes by 2 months / 2,000km and the warranty will still be upheld, but that's not much of an improvement.

The next maintenance interval programmed into the car however does show 12,000km. So you have to be careful as if would trust that you would have missed the oil change recommended by the maintenance guide and that's required to uphold your warranty!

How much did you pay for the prepaid maintenance service and for how long? I ask you this question because I have thought take this option.

I have attached the Hyundai Prepaid Maintenance Matrix for the PHEV. I chose the premium plus as it include some additional items. There 2 choices for both Warranty and PPM. One is Premium, one is Premium Plus. I have the Premium Plus Extended Warranty (Hyundai OEM) and the Premium Plus Prepaid Maintenance (Hyundai OEM) both for 8yrs/160,000km so I don't need to worry about any warranty or maintenance items for that period of time. If you don't use the warranty you get a max of up to $2K back. This was the options I had in Alberta, the pricing and options may be different in other places. The circles on the Premium Plus means you can get the item this number of times over the service intervals. For example, wiper blades can be replaced 1 time during service intervals 3-5, 6-8, etc. Some people think it is not worth the value but I have found, over my multiple vehicles, that the price of maintenance keeps going up and up and up and this allowed me to lock it in at today's prices for the next 8 years. We all remember the $19.99 oil changes from years ago, try to get a shop or dealer to do the oil changes for that nowadays. Let me know if there are any questions and I will try to help out.
