New to forum .Questions about used Genny

[Jerziboi]

Hello, I recently purchased a 2011 4.6 with 85K although the oil looks fine I want to change it so that I know it's been done. Is synthetic recommended? or synthetic blend? I'll probably change the air filter should I use OEM or K&N? Before the winter I'll change the coolant, rear differential and brake fluid. Is their anything else I should pay attention to? Don't see a dipstick for the trans does it use a special fluid?

Thanks in advance!

First, register at www.myhyundai.com so you can download the owner's manual and other doc.

1. I would definitely recommend full synthetic. Use 5W-30 if you are interested in engine longevity instead of the Hyundai recommended 5W-20. I personally use Mobil 1 EP 5W-30 purchased at Walmart.

2. Do not use K&N engine air filters. I would recommend OEM, but there are some others that are OK.

3. Coolant and rear differential are probably easy to change. Use Hyundai OEM coolant.

4. Brake fluid is not easy to change, and requires special procedures to flush through the HECU (anti-lock system). Only use Hyundai DOT-4. The National Highway Traffic Safety Administration (NHTSA) issued a recall on this, so ignore owner's manual DOT-3 specification. I would have the dealer do it.

5. The ZF 6-speed Transmission for the 2011 V8 uses special fluid (not just any synthetic). The transmission is not designed for easy changes. I would have dealer change it, even though it will be expensive. The fluid alone is a couple of hundred dollars.

6. Cabin filter (in glove box) should be changed at least once a year. Use OEM or after-market. Video's on youtube and other threads on how to do it.

7. I would highly recommend OEM oil filters. They are cartridge type filters that fit into a plastic housing made by Mahle. You can buy the OEM ones at online sites where dealers sell Hyundai parts, or at your local dealer.

For certain items I mentioned above, a car like the Genesis simply is not as easy to maintain, even for an experienced independent mechanic, as were most older cars.

I've used full synthetic in all my motor vehicles (on/off road, motorcycles and boats) for many years and never had an oil-related problem or wear issues. For my Genny I change Mobil-1 40-15W every 5,000 miles. I run a higher thickness because I live in the SW desert where it gets extremely hot during summer.

Unless you are concerned about getting every little ounce of performance out of your Genny I would stick with the OEM air filter (and definitely oil filter). K&N's are OK for track use but I wouldn't use them on the street.

Check your owners manual (or the website) for recommended fluid service. Off the top of my head I think the transmission is sealed and the fluid serviced at something around 100,000 miles (I may be off on that mileage so check to be sure). There is no tranny dipstick.

For my Genny I change Mobil-1 40-15W

The only Mobil 15W-40 oil I can find is Mobil Delvac 1300 Super 15W-40, which is not a synthetic oil (notice it is not called Mobil 1 Delvac). In addition, I am not sure it meets Hyundai specs.

I would consider using Mobil 1 EP 5W-30, which I do not believe will break down in 115 F ambient conditions. Another choice is Mobil 1 0W-40.

The Transmission is a german made unit, ZF transmission. I have had mine changed every 70,000 miles or so. It is a sealed transmission and does use special synthetic fluid and the filter is built into the pan . So a fluid filter change that includes the the pan filter is about 600.00 to 800.00 dollars at the dealer. Its worth it if you are going to keep the car. FYI the transmission in the 2011 4.6 is the same zf transmission used in Bentleys, BMW large sedans, Jaguars and other Luxury cars. Some dealer service departments do not know about the pan/filter or the special fluid required, so do your homework and ask questions about the person's experience that will be doing the work. A screw up is very very costly. A new transmission cost as much as 8000.00. My car has nearly 187,000 miles on it and the transmission is still running and shifting like new.

Thank you all for the great information I try to avoid the stealership as much as possible so maybe I will buy the OEM oil filter and have it put on at Pep Boys

I also try and avoid the dealership, which is one reason I change my own oil. But in the case of the Genesis (and its cartridge oil filter), I would use the dealer if I couldn't do it myself. It is important to install the cartridge correctly and change the O-rings correctly, which I would not want someone at Pep Boys to do if they don't have experience with the Genesis.

Check around and get some quotes from dealers before you decide. You can also usually bring your own oil (synthetic, etc) if you want that, and they will usually give you a discount on the oil change. Some dealers do use a synthetic blend (according to some who posted on this forum) instead of conventional oil, which is a decent compromise. Just ask them what oil they include in their oil changes.

STAY away from Pepboys when you have a luxury car like the Genesis. The techs at places like Pepboys are poorly trained. Even some dealership techs are not familiar with the engineering of the Genesis. Find an indie shop that works on high end Japanese and european cars and you will be better served. Don't go cheap with the Genesis, it will cost you in the long run.

Point well taken thank you
