Yet another oil question

[2012AccentSE]

I called the dealer to get specs on the type of oil they use out of curiosity. To my suprise, they do not use the Valvoline Durablend that I thought they did (the service advisor originally told me it was Durablend). Instead, they use Shell 5w30 synthetic blend for their bulk oil changes. The only Shell oil product I knew about was Rotella lol.

Is this a good oil? I hope I can go back to using 5w20 at 30,000 miles, which is ACTUALLY spec'd for this car....

5w20 and 5w30 are both spec'd for the vehicle and either can be used at anytime.

This is probably what they are using

I can't see them using Rotella T, it's excellent oil however quite expensive for a blend.

Your future plans for the vehicle will determain what grade to use......
-5w20 if only keeping it for a few years, up to 100,000miles. Use what ever you want that meets spec
-5w30 if keeping it till the wheels fall off.........200k+++ Synthetic, Synthetic, Synthetic......

As long as it meets the oil requirements the manual states, you're fine. Or just do your own or go somewhere else.

why is this?

On the rotella note, a lot of subaru guys run it because it holds up well under the stress.

Rotella is a diesel engine specific oil. You don't want to be using that with a gas engine. Stay with a name brand regular or synthetic 5W 20 or 5W 30 oil, change it within warranty guidelines, use an OEM Hyundai filter, and sleep easy at night.

Absolutely it's great oil as stated before.......

However synthetics will always outperform a conventional or blend especially in extreme cold starts, and excessive heat.

Diesel oil in a gasoline engine is fine if it's fairly new. The problem is diesel oil has additional detergents in it to keep the interior of the engine spotless, this can work "too" well in high mileage engines and cause external leaks, and loss of compression in piston rings

If it does not meet API SN rating for gasoline engines, you will void your warranty if you have an engine lubrication issue. API CI is the latest for diesels. Stick with SN rated oils.

THANKS.........but anyone who knows anything about oil, knows that API certification is far obsolete on it's own, and by no means a guarantee of quality.

When you look further into base oils, additives, actual oil specifications at different temps, etc........."product data sheets", then you will begin to see what are good oils, and what ones to stay away from.

At this point you can tailor a specific oil to your car, and the demands you put on your vehicle, and what you expect it to do.

As for warranty, this is up to the manufacture to prove beyond reasonable doubt that it was the oil which caused the failure. At which point they must prove that the oil manufacture is making an inferior product. Oil companies to not take kindly to this, and have millions to fight stuff like this in court.

Just my 2 cents

Go for it if you are up to it.
I am pretty sure 99.999% of the folks want no fuss no muss motoring and don't want to battle Hyundai in court because they didn't use the manufacturer spec oil.
