I am going to apologize in advance for asking a dumb question but what mileage/time interval is transfer case, and differential oil changed? I have read that the ahc fluids were flushed was changed at 60,000 miles at a lexus dealership.

If not used off road or in dusty conditions or pulling a trailer or heavy load it’s not on any of the maintenance intervals I would think 60,000 would be a normal time to change for one of us on mud that were freaks about maintenance
 
I'd add my own oil to top it off at this point. I don't want to call someone on the carpet and then entrust my engine to them.

Also, check for any hairline cracks on the top of the radiator around the square where the part number is stamped. Many a tech is unaware that these are a weak spot. Being a 2013 the radiator is most likely still in good shape though.


Thank you very much for the heads up on the radiator. I will have salesman take a photo of the radiator and text it to me. I am assuming you can easily see once you open the hood.

Odds are you are good to go with a 2013 but TexAZ has a good pic of the hairline crack that leads up to the failure in this thread.

I took the shrouds off of my LX the day I bought it but IIRC the rad is hidden underneath.
 
thank you for the link. I have looked at a lot of photos. I know exactly what to look for. i will kindly ask the sales guy to take a photo of the radiator stamp. Hopefully, he will before my trip down there.

I don’t see cracks. I am posting photos. Please chime in.

As you will find discussed at length on mud, this is a common failure point and often first presents with a hairline crack here. I can’t tell for sure from your pic, perhaps others can, but I’d clean it up and examine it more closely.
 
So, the service tech at the mercedes/bmw dealership who changed the oil stated they will add additional quart of oil The oil spec is Ow20, bmw twin power. Does that mobil one make the bmw twin power.

Careful, you don't want the twin power in the vvt-i.

It is spec at 0w20 and full synthetic. can you please elaborate on why? I am not trying to argumentative but trying to learn on why.

You can run 5W 20 oil he just have to change it every 5000 miles 0W 20 synthetic you can go to 10,000 miles I always change at 5000 and use 0W 20 My Lexus dealer uses 0W 20 Kendall titanium synthetic it meets specs for our engine not made by mobil i’ll attach my used oil analysis so you can see how great The Kendall oil is
