Hyundai Genesis coupe 2.0t recommended oil viscosity from the owners manual. 

Make sure you use a 40 normal operating temp viscosity the 2nd number and select the correct cold dry start viscosity the 1st number pause the video with a clear shot of the oil chart put your finger on the coldest winter temperature it gets where you love move your fing down and any of the viscositys that your finger touches regardless of it being on the 3.8 section you can use that 1st number and any 1st numbers that are closer to 0w which is for places that are colder than -30°c / -20°f. For instance it is no colder than 30°f in Arizona where I live so I can use a 15w 10w 5w and a 0w as my 1st number and always in a 40 viscosity.

People still don't want to listen even when the facts are presented to them. With the *1 and all of the failed engines with bad bearings they still use 5w30 or 5w20.

You lower the 1st number in the winter based on the temperature chart not the 2nd number. The 2nd number is when the oil itself is at normal engine operating temperature. The 1st number is when the oil has not been warmed up and has not been in use so it is at ambient temperature.

@@jeffreycattelino3996 so you suggest 0w30? or 0w40

I only recommend a 40 viscosity a 0w 5w 10w or 15w. Was that fahrenheit or Celsius?

@@jeffreycattelino3996 Fahrenheit, guess I will be light on the throttle this winter until i change it to 5w40 in the spring thank you

Change it now with either 15w 10w 5w or 0w 40

I use conventional oil for me it is about cost of oil and my oil change intervals. The cost is less than $20 for the oil and I use it for 3k miles then change it. My thought process is to change the oil sooner rather than later no matter the type of oil. Changing your oil is less expensive than changing out your engine or rebuilding it.

@jeffreycattelino3996 You are 100% correct. i am in the process of rebuulding my nephews engine, and after that, rebuild another one since i have 2 complete longblocks. Folks OIL is cheaper than an engine rebuild.

No problem just making sure the community stays informed so they won't have to replace their engines sooner rather than later. I have a big stock turbo all the boltons even a water methanol injection kit track race drag race my genesis and it is still going stock not built engine using 15w40 conventional diesel oil

I change my oil 3k miles to 4k miles

No quaker state paid Hyundai money to put them in the owners manual. I use rotella t4 15w40 conventional diesel oil or autozone stp 15w40 conventional diesel oil or Walmart supertech 15w40 conventional diesel oil. I live in Arizona usa where it is only getting to 30°f 0°c overnight so the 1st number doesn't have to be any lower for example 10w 5w or 0w to circulate the oil quicker during cold startup after the car sitting for a long time.

You're welcome

@@jeffreycattelino3996 What can I talk about your channel...?

@@jeffreycattelino3996 To grow your channel.

I could have but most owners wouldn't understand it in that little time

Regardless of what the cap says you should use 5w40.

Even in the winter?

@@ohgeeesyy even in the winter what?

@@jeffreycattelino3996 even in the winter i should use 5w40?

@@ohgeeesyy why would it be an issue in the winter?

When your bearings are fucked they wear down eventually and due to that there is now space and the rid can move around and make a knocking nosie with it hitting the engine due to it not staying aligned.

Yes its too late how long will it last after the fact no idea

If it is too far gone by the time it's been through several owners and not maintained properly it's just a matter of time but to prolong the failure it would benefit from using 40.

you get rod knock because you have people adding only 5 quarts even tho it says "5.6" in owners manual. these engines eat up oil

You get rod knock from using a viscosity lower than a 40 viscosity oil even if you have the correct amount of oil in the car.

Thanks for the comment lol
