    Default Oil Change 2017 G80

    Members don't see this ad
    The owner's manual specifies ACEA A5/B5 oil for the 3.8 unit. So far, Pennzoil Ultra Platinum is the only one I have found - I did not get into specialist brands. The Mobil 1 product finder says they do not have a suitable oil. Some of the other oil companies do not show Genesis at all, and some do not even have a 2017 year option for any make.

    Anyone know what the dealers are using?

    Since the vehicle and engine is identical to the 2015 and 2016 Hyundai Genesis (safe the badges), just enter the 2015 or 2016 Hyundai Genesis as a model, and you will have all the results you need.

    Here's one example:

    Don't worry about the ACEA A5/B5. This is a complicated subject, but here are the definitions:

    • A1/B1: Stable, stay-in-grade oil intended for use at extended drain intervals in gasoline engines and car & light van diesel engines specifically designed to be capable of using low friction low viscosity oils with a high temperature / high shear rate viscosity of 2.6 mPa.s for xW/20 and 2.9 to 3.5 mPa.s for all other viscosity grades.
    • A5/B5 Stable, stay-in-grade oil intended for use at extended drain intervals in high performance gasoline engines and car & light van diesel engines designed to be capable of using low friction low viscosity oils with a High temperature / High shear rate (HTHS) viscosity of 2.9 to 3.5 mPa.s.


    Notice that for a 5W-30 oil (which is specified for the Genesis V6), that the High shear rate (HTHS) viscosity of 2.9 to 3.5 mPa.s are the same specification. The only difference would be if you used a A1/B1 5W-20 or 0W-20 oil.

    Mobil 1 5W-30, Mobil 1 5W-30 EP, and Mobil 1 0W-30 would all be excellent choices. Mobil 1 5W-30 Annual Protection would be the best, but it is priced almost twice the price of the others.

    What the dealers are using should be your last question - they are likely to be using the cheapest stuff that money can buy

    The oil filler cap does say 5W30 on it, but in the Manual's fluids specifications section for the G80, it has a temperature chart that recommends either 10W30 or 5W30 depending on your climate's temperature range. It doesn't specify one or the other. In Florida, it would be 10W30. Is the consensus to use 5W30 as the default regardless of low temperature range?

    A synthetic can span either the 5W-30 or 10W-30 viscosity range very easily without viscosity breakdown over time. So a 5W-30 is better than 10W-30 because even in warm climates, since it helps the oil to flow very quickly at engine startup (5W).

    For a conventional oil, it is harder to create a 5W-30 than a 10W-30 and requires a more additives for the 5W-30 oil that break down over time. Due to the more rapid viscosity breakdown of conventional oil (compared to a synthetic), the 10W-30 will hold it viscosity rating for a longer number of miles at higher temps.

    In both cases, even though the 100C viscosity SAE grade is "30" the actual viscosity specification varies a bit. This is because the SAE grades allow for range of viscosities within a specified range that is wider than most people realize. You can check the detailed specifications at the oil manufacturer website for both the 40C and 100C viscosity rating.

    Aside from what the Genesis Owner's Manual says, very few (if any) newer cars specify 10W-30 anymore. If using a synthetic, I would only recommend 10W-30 for an older car or an engine that uses oil with a lower viscosity.

    After I had my first (free) oil change at the dealer, I called and ask what kind of oil they used. I was told it was 5W=30 conventional Quaker State oil.
    I got a factory oil filter (from another dealer), 2 cases of 5W-30 Mobil One oil. I changed the oil about 200 miles later. It has been Mobil 1 at 5000 miles sense.
    I am sure that the QS is as good as any other conventional oil now but I remember the time when it had a lot of sulfur in it and you could smell it when it came in the door.
    It would turn to sludge starting at about 5000 miles and destroy an engine in 25K miles if it wasn't changed. I would never do that to one of my engines but if damage is done that quick, it probably was damaging some at lower mileage. In other works, I wouldn't put Quaker State oil in my lawn mower much less my Genesis.

    Just my opinion.

    Anyone changing their own oil would be crazy not use a synthetic like Mobil 1, due to the small difference in price. BTW, the price of Mobil 1 in a 5-quart jug at Walmart is only about $25, much lower than by the quart. They usually beat the Costco price even when Costco has it on sale.

    Quaker State is now owned by SOPUS (Shell Oil Products US), which also owns Pennzoil, so it is a decent product these days. QS makes a decent synthetic oil in addition to their conventional oil and synthetic blend.

    I am well aware what the specs say - first thing I looked up. Personally, I've been using Mobil 1 for years, have run it in my Vette from new. I switched to the High Mileage version a few years back as it is a better match additive-wise to the older Mobil 1 specified for my car, i.e. before they reduced the ZDDP levels.

    Results from the Mobil 1 product selector, BTW: "Based on what you've told us, your vehicle manufacturer recommends a 5W-30 viscosity and oil that meets ACEA A5/B5. We currently do not offer any motor oils in the United States that meet these specifications".

    Maybe I should demand the dealer uses the "right" oil when it goes in for it's first free service......or complain to Genesis that the dealer is not using the specified lubricants. Fun either way.

    I'm thinking that Hyundai went to that Euro oil spec without giving much thought as to what was available in all their markets and probably have even left the US dealers a little flat footed.
    I'd be really curious to see/hear what the dealer has to say regarding what oil they use or what spin they put on it. It would also be nice to have it in writing.
