Hey all, I am kinda new to picking out oil brands, I've heard many different things about different brands and I can't seem to land on one that I feel comfortable with yet. I've been told Royal purple, amsoil and valvoline are good brands. I want to stay away from Mobile 1 due to the history with the old velosters, even if some say it's fine for this car, I just don't want to risk it.

I also know very little about picking the temperature ranges on oils or what exact oil to get from a brand. I've seen some brands have multiple kinds of the same oil temperature ratings that are like 'non-premium' oils for turbocharged engines and 'premium' ones for turbocharged engines which provide different 'guarantees' of protection, but i'm not sure if this means much. I am guessing for texas weather year round that 5w-30 or 10w-30 is fine? I just can't seem to pin down a solid answer for myself and I would really like some help.

Texas weather can be fickle, next week we will see temperatures down in the mid 20's and up to the mid 60's... Summer can be up to 100 degrees sometimes a little more. But generally summer is around 80-90 degree range.

Anyway, I am at 3,000 miles right now and would really like to jump out of the OEM oil. I have an entire week off of work starting today so I will have the time to take care of this.

Also, I've been through the big thread on the forums here about oil changes, but I am still just unsure about what I should go with.

I'm located in Dallas and currently have Motul 5w40 in, I will be switching to Amsoil 5w30 on the next change though to see which the car likes.

No reason for us to run 0w here.

I saw a thread on here in regards to the oil used in veloster N. The dealership put 5W 30 in on my first oil change even though my owners manual specifically states 0W 30 only. I swear i could tell the difference. I went on my search... i ordered royal purple 0W 30, backordered.... waited over a month and finally ordered monile 1 0W 30 until i could get the purple, seems that it hard to get during race season. Immediately after i had the mobile one put in. I saw someone warning NOT to use mobile 1.... i am now freaking out.

I don't know alot about motors, i know transmissions so im not mechanically handicapped. I am way more familiar with the old school mucle cars. This is my first trip down the turboed foreign cars. I LOVE this car. It has never had anything but premium gas, but now the dang oil is driving me batty! Do i need to quickly get the mobile 1 out? And will royal purple (our go to normally for performance) going to work with this motor.

I plan on trading this in on the performance model before 100,000, it was not available anywhere i could find when i bought this one....

Not so, you need to look at the different viscosities listed in the manual. I wouldn't put Royal Purple in anything. You're reading about the Veloster 1.6T Gamma first gen motor. The VN utilize the 2.0 T Theta II engine and has no such problems. Anyone who said not to utilize Mobile One in this engine, doesn't know what they are talking about. Relax!!

I went ahead and got "AMSOIL Signature Series 5W-30 Synthetic Motor Oil" put in to my car. I've heard a lot of good things about it and I saw a guy do an unofficial test on AMSOIL VS Royal Purple and it seemed to hold up pretty well. As far as Mobile 1 goes, I've seen those discussing the problems with it in previous generations of the veloster, but those were previous generations. From what I've read on these forums, you should be fine with Mobile 1.

How do you guys tell what motor oil the car likes?

Unofficial, but yielded some results.

I was raised in Spring, just north of Houston actually. I don't miss how everyone loses their minds and the ability to drive every time it rains, but sadly where I live now no one knows how to drive in the first place.
I do actually miss being able to do 90 on I-45 next to a state trooper doing the same speed though.



I did say that the 0w30 works better in my current temps though. I am aware that in more moderate climates the 5 and 10w oils are a better choice. I too would not run a 0w oil in Texas under any circumstance.

You're going to get a wide range of takes.

I'm using Motul X-Clean EFE 5W30. I like this oil as it is a mid-SAPS, ACEA C2/C3 (C2 noted in our owners manual), and it does very well when it comes to staying within grade even when used with engines that thrash the **** out of oil (such as the EJ257 in the WRX STI, which will destroy most SN RCs). Two UOAs with my VN thus far indicate 5,000 mile intervals work well even with hard driving. There was a comfortable amount of additive left, fuel dilution was not an issue whatsoever, and it came out effectively the same weight that it went in. This is a dexos 2 oil, which for a long time I believed did not go through LSPI testing - however, based on things I have read on BITOG, it appears dexos 2 and dexos 1 gen 2 both go through a LSPI mitigation test. That said, LSPI was not and is not something I was most concerned with, and I was more concerned about shear stability. Wear metals in my UOAs have been notably low, although neither of these UOAs come from OCIs done over the coldest period of the year. I intend to continue using this oil during the cold months and perform a UOA on the next change.

All of that said, it makes sense to me to do periodic UOAs, and I think it is even more important now since our engine is still relatively new (it uses different internal components than other Theta II engines.)

If you haven't heard of Project Farm, it is a pretty well respected Youtube channel largely about engine maintenance. He recently did a full bracket "championship" between pretty much every full synthetic oil brand you can buy, testing things like wear protection, volatility (which is hugely important in a GDI engine) flow properties, etc. The short answer is that Amsoil won, but by a very tiny margin over Penzoil Ultra Platinum full synthetic. With Amsoil being more difficult to source and costing more than twice as much, I (who also live in Texas) am going with the Penzoil 5W-30.

I'm currently using redline 0w-30 full synthetic and my engine oil temps are lower and the car seems to be responding better. I used before(1k mile break in) the motul 0w30 long life and it was ok, the car temps for oil seemed to be higher and responsiveness was not that great.
