The argument that SM is superior then by spec, resides mostly on the improved basestocks that the manufacturers had to use to meet the spec. One need only look at an oil like Mobil Clean 7500 to see how they are attempting to compensate for ZDDP by adding more radical additive chemistry. There's no question the additive packages are weaker. Many of them are the function of the basestocks and not the additives, i.e., it is dificult to engineer a modern multigrade SM 5w30 with Group I basestocks. I have already seen the specs before I started this thread. This debate has been done on this board many times before your registration, and I'm sure it will rage on in the future. In an engine that doesn't use oil, your converter will not be 'ruined'. Also interested in filter recommendations. I do lots of short trips and frequent driving above 90F so I definitely qualify.Īny recommendations.let's hear em.
The severe service schedule is 3 mos/3,000 miles. I'm probably going to have to change every 3,000 to stay in warranty compliance, so probably dino is in order, unfortunately. And, being able to use SJ oils would probably allow for usage of CI-4+ diesel oils, which have much higher ZDDP levels. Regardless, it seems like that for 97% of the time around here, both sources would be ok with 10w30. Now while I would certainly like to get better mileage, I would also like to get the lowest wear readings. However, the engine oil is not available in your country, select the proper engine oil using the engine oil viscosity chart.
#2006 KIA SPECTRA SPECTRA5 MANUAL#
This is a big departure from what's in the factory service manual.Īdditionally the owner's manual says: "For better fuel economy, it is recommended to to use the engine oil of a viscosity grade SAE 5w20,5w30 (API SJ,SL / ILSAC GF-3). 5w20 and 5w30 are allowed from the bottom of the scale to the top. 10w30 is ok from -5 to 120F, which would certainly encompass any conditions I am likely to encounter here in Texas. It gives the specs as SJ,SL or above, ILSAC GF-3 or above. The owner's manual seems to paint a different picture. This is the kind of recommendations most manufacturers made up until the early 80s, but haven't been seen in quite some time. 5w30 is stated to be only for use in temps below 10C.
It seems to state that 10w30 is OK up to 40C, but that 10w40 and 15w40 should be used for temps above that (we do occasionally exceed 40C/102F here in the summertime). In there, it mentions using an oil of API SH or above and ILSAC GF-1. The factory service manual is actually available ONLINE (!!!!) at the following address:Ĭhoose the options for Spectra, 2006, and 2.0 to get the service manual for my car. Manufacturer's recommendations are all over the place.
I haven't found that many UOA's on Kia vehicles at all.Įngine is a Hyundai 2.0 "Beta II" with variable valve timing, or CVVT as they call it. I'm looking for oil recommendations in the beast. In the shocker of the year, I have traded in my 2004 Nissan Titan for a 2006 Kia Spectra 5.
