G80 5.0 V8 OIL ADDED

[G-307593]

Hello all,

I'm new here, so please excuse my inexperience. Almost a year ago, I bought a new 2020 G80 5.0 AWD model. Due to this virus situation, I've only driven about 12,000 km (7,500 miles) since last March. I followed the break-in procedures carefully, but had to add 1/2 a quart of oil at about 8,000 km (5,000 miles). I could have added a bit more, but didn't want to overfill, so probably added less than I could have. I added the other 1/2 quart at about 11,000 km (7,000 miles). I was very careful to seek a level place (not so easy) to check the oil, after at least a 5-minute wait after warm engine shutdown, as per the owner's manual. First service is due at the end of this month. I've heard that new engines burn some oil on break-in. I've also heard that newer engines burn some oil due to higher compression engines and/or lower tension on the oil control piston rings.

Should I be concerned about 1 quart of oil burned in the first 12,000 km (7,500 miles) ? I appreciate you sharing your knowledge and experience with a new Genesis owner. Thank you.
By the way, I love this car. Love it !

1qt in 7,500 miles seems a little excessive. I don't own a 5.0 so I can't speak to that engine specifically. I've never had any oil loss on any new vehicle I've owned.

Consider it may be an oil leak versus burning. Check around engine and under car for oil leaks.

What oil are you using? Does the 2020 still suggest 5W/20? Most dealers are using 5W/30 that I know of for that engine but I've only been to three. Oil is very subjective; this one is way better etc etc...it's your money. As a former racer and having torn down engines and seeing main/rod bearing wear ( our engine vs other engines on other oils ) I have my favorite and that's what I use in all my cars when I do the change.

I've seen some oil tests on YouTube videos and they are of questionable value. Showing different oils running down a track does not show me much about performance in the engine. Real world comparison of wear makes a difference.

I'm not running videos Ed, I'm talking about taking engines out of the car for a complete rebuild, tearing them down and looking at bearing wear over two seasons with the two main oils that people carry on about here. One set of bearings were way better than the other. Hope that's real world enough.

Curious if you see any signs of oil leaks underneath, or any blackening around the tailpipes? A quart does seem like a lot, my 3.8 engine doesn't burn any.

If you consider the month and year when the car was built (based on plate inside driver's door frame) you're probably well past the one year mark, anyway.

Just my opinion, but oil consumption during break-in isn't much to be worried about. After proper break-in, it should consume less oil.

I wouldn't be all that concerned, I change the oil on all my vehicles at 5,000 miles using mobil 1 regardless of what the manual says. I would say that many of the engines over the past 40 years would use as much as a quart between oil changes and very few wouldn't use any. Keep doing what your doing as far as checking under the hood, most people don't do that these days. Enjoy the machine.

Pics please?

The car is under warranty so explain your concerns to the service manager at the dealership. You do have a new car warranty for a reason.

Don't shoot the messenger here, there is no dealer, and certainly no car manufacturer, that's going to bat an eye at one quart of oil usage in 7,500 miles. That is absolutely in the realm normal operation. Most car manufacturers (again don't shoot the messenger) will tell you that an engine that uses up to a quart every 1,000 miles is considered as normal (I suspect the warranty dept helped determining that parameter).....I know that is obsurd, but that's what you will hear from the dealers and manufacturers.
All you can do is demand a high quality synthetic is used at the oil change, most dealers really don't care what goes in your engine except for the Viscosity #(use 5w30). The better synthetic oils keep their viscosity longer, which helps keeping oil from getting past piston rings and valve seals. Better oils also have lower evaporation rates as well, that reduces the oil loss through the PVC system.
The Genesis V8 has a very large sump, 8.5 quarts or more depending if you have AWD or not, ONE reason why engineers design in a large sump is to make sure there is enough oil to last from oil change to oil change with out getting dangerously low as to starve the engine from it's life blood(few people ck their oil routinely these days).
If you don't have any oil spots on the driveway and it doesn't smoke like a chain saw, you don't have an oil consumption problem.

In my 45 years of driving and probably 15 cars (20 counting the kids), I only remember one that used oil - a 1969 Lincoln Mark III with a 460 V8.

Had a few older cars that used oil but they were pretty beat. Can't remember the last time I actually bought a quart to add. Manufacturers though, still stick to the quart per thousand miles as normal.

My '53 Mercury had to have every fluid topped off monthly. Used to buy re-refined oil for 50 cents a quart.

Lol I had the same routine and bought the same type of oil on my '49 Ford with the flathead V8.

My 2015 has the same delightful 5.0 engine. When first purchased in 2016, I thought there was an oil consumption issue but it was the dealership not filling the engine properly. They were relatively unfamiliar with Genesis models and the same size engine in the previous years model took quite a bit less oil to fill. They were putting the same amount of oil in the newer model. I caught it on the next oil change and alerted them right at the dealership - oops was all they said... That's when I decided to do my own oil changes and have never looked back.

A second issue that I've seen is that reading the oil level is best done in the morning before starting the car, using the same parking position each time. Even after changing the oil I'm hesitant to be satisfied by filling to the full mark on the dipstick and be done. The next morning before starting the car I usually see the need for another 1/2 litre to get the level back to full. It might use 1/4 litre between changes but that's it. The oil filter cup does seem to seep a bit of oil for some reason (new o-ring installed each time) which may account for some of the usage but not other leaks. I'd rather see them use a cartridge filter - never had those seep oil.

You are right about loving this car - this is the first car that I've had and not even remotely considered trading it on something else!
