Synthetic Oil Changeover

I will change to Mobil 1 and as I live in the Phoenix AZ area the book says due to the sand to change the oil more frequently.

Good move - I have used Mobil 1 for forty years - I had extensive discussions with the engineers who developed and patented the stuff in the '70's as to the advantages and the reasons for its development.

And, I'm not about to preach its advantages to others. I learned a long time ago that people value most that which they learn for themselves after expending a little effort. In other other words, free advice is mostly a waste of time.

Nitrogen in the tires? All for it - I keep mine inflated to at least an 80% nitrogen level.

Do the 2015 come with Nitrogen in the tires?

Thanks

Hello, John. I did my first oil change (to Mobile 1 5w30) at about 1,000 miles prior to a 1,300 mile road trip. With a direct injected engine, I want to keep the carbon build-up to as little as my actions allow. Maybe conventional oil is "just as good" but I'm not going that route with any vehicle that I own, including my lawn mower. My peace of mind is worth more than the extra $30 per oil change.

When you get back let us know your thoughts about the Genny as a road trip car and the gas mileage. My next road trip is not until September; I plan to use only premium gas on that trip to determine if it makes a noticeable difference in my V6 Genny.

Enjoy your new car.

Greetings.. Something that I'm really not tracking on is which viscosity is everyone using? According to Mobil 1 web site Genesis recommends 5W-30 but they also make a 0W-30 (and state it can be used). 0W-30 is suppose to somehow give you better fuel economy.

Would a dealer tell you either is fine or recommend you use #W-30?

Thanks

All cars come with approx. 80% nitrogen in the tires (at least). See my post above.

Getting the nitrogen content above that level is a little discussed and rather difficult problem. A couple of chemical engineers on an old Sonata forum once calculated that "draining" and refilling the contents of a tire five times with nitrogen would only get the nitro level to about 95%.

And - note to Benji - on oil viscosity - it's always printed on the filler cap - for starters, at least.

No, don't ask a dealer about that. They may have an opinion, but they have no clue what they are talking about.

Mobil 1 5W-30 and Mobil 1 0W-30 are both fine for an engine that specifies 5W-30. Some 0W-30 synthetic oils are actually European Formula oil, and should not be used in a Genesis, but Mobil 1 0W-30 sold in the US is not one of those. A European Formula oil (for use in BMW, MB, etc) will say so on the label.

Mobil 1 0W-30 has a larger percentage of Group IV/V synthetic base stock (as opposed to Group III base stock) than Mobil 1 5W-30, unless you get Mobil 1 5W-30 Extended Protection oil, and therefore Mobil 1 0W-30 is probably a better quality oil, but both far exceed Hyundai specifications.

I believe that air is closer to 79% nitrogen.

Regardless of the fact that one can not easily get 100% nitrogen in tires, if you go to a tire dealer like Costco Tire (which does not charge extra for nitrogen) they will put enough nitrogen in your tires that the tires will leak less pressure over time than regular air (79% nitrogen, 20 oxygen, 1% other). I know people snicker about this all the time, but everyone I know who has tried it (including myself) has found that to be true, usually to their amazement.

And, I believe that I said "approx. 80%" in my post.

As far as Costco, when you can produce quantitative figures on just what that company actually accomplishes - I would like to see them. I most certainly would be amazed - esp. coming from Costco.

Sorry, I though you said "at least" 80%.

I am not sure what you mean about your comments concerning Costco. I didn't say they can get 100% nitrogen in the tires. I said that whatever percent they end up getting in there, will noticeably reduce the amount of leakage over time. I and several others in this forum have mentioned that, even though we were skeptical before we tried it. From what I have read, 95% nitrogen will noticeably reduce the amount of air leakage over time.

I don't know if Costco is better at getting a larger percentage of nitrogen in the tires than any other tire dealer that offers nitrogen. However, I will say that Costco Tire department has the best customer service of any tire dealer I have used in my 48 years of car ownership. Discount Tire is not bad either, but Costco is better IMO.

Are you a Costco member? Some people think it is like Sam's (Walmart's warehouse store), but it is quite different. Costco pays their employees among the highest wages and benefits of any retailer, and it shows in the kind of customer service they offer.

Good to know! They called me this afternoon that my Bridgestones are in. Going in tomorrow morning (the only day they are first come first serve, otherwise it's a week and a half). I hope you are right about the customer service!

I have been dealing with Costco since their inception.

I find their personnel, in general, and their tire service, in particular, runs the gamut from quite good to quite bad (almost bizarre, in fact).

Google "costco tire lawsuit" -- interesting reading.

The only lawsuit I saw was for putting 2 new tires on the front, instead moving rears to front and putting new tires on rear (when only buying 2 new tires). Personally, I think that is complete BS, and is just a way for personal injury lawyers (ambulance chasers) the weasel money out of corporations (they sued Costco and GM). You can find lots of hits on lawsuits if you switch Costco with any other tire chain.

The rest of the complaints were typical, and are bound to happen once in awhile when you install millions of tires. Costco warns people on the receipt (in big letters) to inspect the lug nuts within 25 miles after leaving Costco to make sure they have not come loose, but not many do it. I didn't say Costco was perfect, just that they are the best I have used.

You will get free 7500 mile tire rotations at Costco, so make sure you take advantage of that. Tire rotations really do extend the life of your tires, especially on the Genesis.

Also, you get a free road hazard warranty at Costco. Make sure you keep your receipt in the car in case you need it. I had a flat while on vacation, and went to the nearest Costco out of state and they replaced the tire. The cost was pro-rated based on tread use, so only cost me $15 total to replace it (it was fairly new).

But I cannot guarantee that every Costco tire employee is perfect, just that on average they are the best I have used.
 
After 35 years in aviation, I can safely say virtually all large aircraft use nitrogen in tires, struts, accumulators and virtually anything requiring gaseous pressure but the main reason was to avoid moisture, and ice. Recalling my 40 year old college chemistry I believe both nitrogen and oxygen are diatomic and that the nitrogen atom is smaller than oxygen and hence more likely to leak. Just as helium is much smaller than air and why a normal rubber balloon can't stay inflated so they use mylar. There may be a chemical reason a nitrogen filled tire would not lose as much preassure as air but I don't know what it would be.

A few points:

1. The law suit thing is a lot bigger than it appears - in recent years, Costco, Walmart, and Michelin (among others) have had to pay outrageous settlements - many millions of dollars for each settlement. They most likely were not at fault, but when you have an ambulance chaser lawyer and a severely injured client, the big guy with deep pockets pays big. And, you don't hear about them because of motions to suppress publicity. In one case, Costco rotated some tires. Later the plaintiff was severely injured in a bad car wreck totally unrelated to the tire thing. Costco paid like $4M.

I couldn't get my tires rotated after that - no reason given - I later found out about the lawsuit.

2. Lug nuts: At the local Costco, they hand you a slip of paper telling you to bring the car back next day to have the lug nuts checked. Obviously, they don't trust their own people. In my case, I always check lug nut torque myself if I even suspect somebody has been near my tires. And that slip of paper is more protection against lawsuits (they hope).

3. I agree that Costco looks good compared to the competition, but If I told my stories about the competition, I would go on forever.

Kind of hard to do on my Genesis (properly, anyway).

Thanks Mark... I thought as much about Mobil 1 0W-30. Thanks again..
 
Did I see correctly? Does the 3.8 take 7.2 qts? What is the genral price total, synthetic, to change the oil & filter??

Didn't see an answer to this first question.

Does the 3.8 take 7.2 qts? I am about ready for my first oil change and was going to bring Mobil1 from Walmart and want to be sure I have enough.
