Dealer Oil....

[kdw75]

Our dealers service department seems to do pretty good work, but there is one thing they have always done that gripes me. On our '08 3.3L Santa Fe I would always take in my own synthetic oil at oil changes. They would invariably call me and inform me that the 5w-30 I brought in didn't match the 5w-20 that was printed on the engine cap. After I insisted they would finally use my oil, but were hesitant saying "Are you sure you don't want to follow the manufacturer recommended oil?" Then I showed them where the book recommended 10w-30 and then they of course said that I was giving them 5w-30 which still wasn't what was recommended.

It turns out that they have a huge tank of 5w-20 and put that in everything unless you bring in your own oil. Today my wife took in our SF 2.0T for it's first oil change and when I looked at the paperwork I see that they used 5w-20 oil. The book says to use either 5w-30 or 10w-30.

For some reason they seem to just love thin oil. On a turbocharged engine that is sometimes run pretty hard in temperatures in excess of 100 degrees I feel that something heavier is going to give better protection. Heading into Winter the lighter oil might be ok, but come next spring I certainly don't want more 5w-20 so I guess I will go back to bringing in my own oil.

What do you all think? Am I worrying too much or do you think I have cause for concern?

Same concerns here... Am curious to hear some feedback

If the book doesn't say 5W-20 then don't use it. Most other turbo vehicles I am aware of require thicker oil like a 40 weight. I would also use synthetic only in a turbo. Since you have a new filter a simple drain and fill with the proper oil should be fine. This would bother me so I would probably do it very soon.

Amen. That is the one thing the dealer skimps out on, oil. They buy the cheapest bulk oil they can find and use it on everything.

I work at a Hyundai dealer and we actually use the correct oil, which is 5w20 for the new Hyundai's. Different viscosity oils is not good on the engine with how tight clearances are internally and with variable valve timing, solenoids, etc. that monitor oil pressures etc. We see vehicles come in with issues due to wrong viscosity oils in the engine...admittedly way more Chryslers and Hondas but occasionally Hyundai's as well, especially after the GDI engines came out. I'd use 5w20 if I were you guys, regardless of your old school thoughts on heavier weight oils and it's added protection at higher temps.

I had this same issue with my 2011 optima turbo. The dealer swore it should be 5-W20. The only issue being the cap on the turbo says 5-w30. I do believe that is the issue here. There is also a claim that you can't use synthetics, which is untrue. As long as the oil is the correct weight for that engine, which is different between the 2.4 and 2.0 turbo, and meets API Service ILSAC GF-4 or above classification then you are set. I pushed the issue so hard the Dealer put up a sign in the service department that read:

2.0- 5-W30 ONLY

Was all I red too. Took several calls to corporate, but worth it.

Same thing happened when we bought our 2013 Santa Fe. Dealer said all their cars take 5-w20. Showed them the oil fill cap and one call to corporate later. . . Problem fixed.

I have a Sonata Turbo, and in the manual it states use only 5-30, but for "best performance" use 5-40. Also it recommends Quaker State as that's what it was filled with from the factory. I do all my own work, but I use 5-40 esp in the summer, Mobile One.

Except the car, the owners manual, the service manual, and the dealer all say 5W-30 for my car.

With advice like this, it is one reason I have been doing my own oil changes for the past 40+ years. Never an oil related problem and I have never had to add one ounce of oil between changes.
