proper SAE grade for 2005 XG350
The owner's manual shows 5W-20. 5W-30 or 10W-30 as appropriate weights.
When I access the hmaservice.com site it show 20W-50 for elevated temperatures. Why the discrepancy, why the difference and what weight is suited for 115-120F AZ desert temperatures? Thank you, Seamus J. Wilson |
Re: proper SAE grade for 2005 XG350
Yes, I have the same engine in my 2005 Kia Sedona minivan. When I bought it
new, I looked over the recommended oil viscosity chart, and I commented to the service tech, "I haven't seen a chart like this since the 1970's. No one does this anymore." The recommended viscosity for hot weather is my Sedona is supposedly 15W40. However, I have always run 5W30 synthetic year round, and everything has worked out fine. If one had a concern (like hot Arizona weather), I might be talked into going as high as 10W40, but I can't really believe you would want to put 5W30 and 20W50 in the same engine. My question is, what have you been putting in it up until now? My hunch is that your engine will continue to do well with whatever you have been doing. Keep the oil changed (that engine seems to need frequent oil changes), and you will do fine. Hope this helps! "Seamus J.

Seamus, I have a 2005 XG350L and have used 10W-30 Mobil 1 since I have owned
it, I live in Las Vegas so we have basically the same weather. ']['unez "Seamus J.

Seamus,
I live in NW AZ and as Tunez mentioned, we have the same weather. My dealer uses Castrol GTX 10W30 for our climate, which is starting to warm up. Been using the same oil in both Sonatas 2002 and 2006 since we bought them new. Flew back into Vegas last night from a business trip and it was 96 at 8PM! Steve "Seamus J.

Most owners manuals for cars I've owned show a temperature range chart for each recommended viscosity, but I can't remember if my Sonata did or not. Matt |

Matt,
The owner's manual only shows SAE grades, no temperature charts or references. Best and thanks for reply, Seamus J.

I can't believe you need 20W-50, but I'm not going to argue with hmaservice. Personally, I'd use a 10W-30 full synthetic and not worry about it. Matt |

I don't care if the dealer said it's ok, or Hyundai. As a mechanic I have seen many people (including other mechanics) make this mistake. Thick oil like 20-50 is for deisel engines and heavy machines that have a lot more internal slop. Our car engines have tighter tolerances (unless their old and high milage) and because the oil is thicker, it will cause elevated oil pressure wich is fine for the metal but murder on seals. It could cause your engine to develop leaks and possibly start burning the oil. If you want to go with a higher range,10-30 should be more then enough. That being said, It's your car, put in what you want. Bill |
