Took my Genesis 4.6 in for the latest oil change, and noticed the following: Where all previous oil changes have had this description

oil - B Oil

oil - B Duramax

Dealers (or owners) can use whatever brand of motor oil they want, so long as it meets specifications. Duramax is brand of lubricants and other auto maintenance products from a smaller company, that probably buys the stock from independent refineries/distributors so they can sell it under their own name.

It appears that the only oil sold under the Duramax brand is full synthetic or synthetic blend. You are probably getting synthetic blend (mix of full synthetic and conventional), which is better than 100% conventional oil.

Thanks for that answer. I had never heard of Duramax before, again, thanks for the URL, so I guess that they <Hyundai> knows that this oil is OK for their cars. Thanks again.

Your dealer is not Hyundai. Dealers are independent businesses that are not owned by Hyundai Motor America. Dealers buy new Hyundai's from Hyundai Motor America (the importer/distributor), and sell them to consumers, and they provide authorized warranty service on behalf of Hyundai Motor America (who reimburses the dealer for parts and labor for warranty service).

However, I am sure that the Dynamax oils I saw on their web page do meet Hyundai specifications, assuming your dealer uses the correct viscosity (5W-20 or 5W-30 or equivalent).
