I have a 2007 Kia Sedona 3.8L V6 (185K miles) , I believe there is a "semi - controversy" in terms of what grade oil (5W20 vs. 5W30) to use ?
Something about smaller oil passageways in this engine design show it performs best with 5W20 while others say since 5W30 is also suitable (listed in the OM) and can be considered suitable as well ... *What says you Kia engine experts ?

I have a customer with an older 3.8 Hyundai. Last time I changed it I put in 10w30 HM oil. Runs perfect and he says he adds less oil now.

For GA I say at least 5w30 and 10w30 if it leaks/uses a fair amount of oil.


yup

5W-30 is already a light oil. 5W-20 is for sub zero temperatures.

For GF-5 oils with an HTHS range of 2.6 to 3.2 mpas I would always go with the highest regardless of what the owners manual states. Having said that, my friend has a Hyundai Accent circa 2007 who uses 5w20 dino with many successful miles. Use what you're comfortable with.

Put in straight 50 weight for a few hundred miles, and it will stretch those oil passages right out smile

Just use what the manufacture recommends and it is usually on the oil fill cap as well as in the owners manual. Ed

So what oil are you using? Does it burn or leak,etc? What weight does the oil cap say?

I had an old 1978 Pontiac Grand Prix with the dog 301 v8 in it. Near the end of its life, I was running Kendall GT straight 70 weight oil because the engine was so worn out.

Your engine, and you probably won't notice any difference between a synthetic 5W-20 and 5W-30, simple as that.

Oil Cap = 5W20
**Any truth to this engine having "narrow" oil passage ways thus 5W20 is preferred ?
Will also note this engine has a timing chain (not a timing belt) if that matters .
