2009 Kia Sedona 3.8 l DOHC V6 w/ timing chain, VVT on intake side only
I changed the oil and last Fall c. 110K km (70K miles), and used Mobil 1 0W-30 and a Kia cartridge filter. The van now has about 116400 km on it, so about 6400 km (4000 miles) and 6 months on the present oil.
For the previous oil change, I'd left it an entire year - about 12K km (7500 miles).
I would consider changing it now for several reasons:
1. The van does a fair number of short trips over the winter, so these are hard miles.
2. Per BITOG, short OCIs are an important factor in extending timing chain life. (I am leery of timing chains in OHC double-bank engines, but it is what it is - timing belts are going the way of the dinosaur.)
3. I was intrigued by a recent post in which Nissan research indicated that the use of 0W oil seemed to result in higher timing chain wear. In the same post, it seemed that timing chains also did best with oils with a tight specified range (that is, 5W-20 or 5W-30 would be better than 0W-30 or 0W-40).
4. I'm also a bit worried about the VVT issues other manufacturers have had with extended OCIs. (Not that the van is anywhere near an extended OCI yet, but I'd rather err on the safe side.
Thoughts from you wise BITOGers? Thanks in advance.
