Hyundai Beta 2.0 and T6?

[milehigh]

Hello everyone- I have sort of a newbie question.

I drive a 2009 Elantra with 23k. I do 5k OCI's to keep the warranty people happy (hopefully will never need to use it) as the owners manual calls for 3250 OCI for severe usage and 7500 for non-severe.

I drive 80% highway daily, the other 20% is heavy stop & go or short trips (I use my car for work). I have been running all types of synthetics since new. I buy whatever is on sale- current fill is PU 5w20.

The old tech Beta 2.0 in the car calls for 5w20, however the manual states it can operate just fine with 20w50. I live in CO and although the temps here are fairly average, we do get some extreme cold in midwinter (sub zero nights). I would like to start using one oil with one weight for my cars (trying to minimize the amount of "leftover" partial quarts, etc.).

My question is this: I have recently started using Rotella T-6 5w-40 in my old Miata with great success, would there be any issue using this oil and weight in the Elantra? Are there any longterm effects using an HDEO in a gas vehicle (cat issues, etc.)?

Thanks!

What does "with great success" mean?

You can use that oil in the Hyundai, but you may notice slightly lower gas mileage. I don't know what the API rating is on the T6, but if it says it's good for API SM and that's what the Elantra needs, then you should be good to go. With that oil, and really any synthetic, and your driving habits and such, you can easily go the 7500 on the non-severe service, especially considering you're already using synthetic and the manual probably calls for conventional. If the car has a maintenance minder, just follow that and be happy.

The "great success" was solving the valvetrain clatter that seems to plague some older Miata's on start-up. This one keeps is quiet for at least 5k.

I'll check the API on it tomorrow when there is more daylight. Thanks for the tips!

It shouldn't mind it too much. I used it for a short stint in our Hyundai 2.0 with no ill affects. Where my beta has mechanical lash adjustments, yours will have hydraulic with (I believe) VVT.

That's a pretty big viscosity jump from 5w20. I had a 06 Kia Spec5 with the 2.0 Beta with CVVT.

Kind of ironic that you mention quieting start up noise on your Miata with the T6. My Beta made all sorts of clatter for the first few minutes it was on, I swear it sounded like it was about to throw a rod when you let off the gas when it was cold. But when the dang thing was hot it was as silent as an engine could possibly be. I tried 5w20, 5w30 and 10w30, it was all the same. Probably wouldn't hurt yours to try T6.

it shouldn't cause a problem but it's probably not that much better than using QHP for a lower $/quart than T6

both are made by SOPUS btw
