But curious minds still want to know. As you can see below, I'm running a 30 in ours. And our Honda is still under warranty.
Use four quarts of Mobil 1 0W-20 for the receipt/warranty tracking, and sneak an undocumented quart of Mobil 1 0W-40 in there. It'll be on the border of a 20/30 grade, and will still have very good cold start properties.
Nothing wrong with that!
+1 on the sneaky beef-up blend; did this in the 09 EJ forester. But as we shiver in the corner waiting for the dealer to deny our powertrain warranty - has anyone ever had warranty work "denied" for using one grade thicker proper service category oil? I Don't recall reading this happening anywhere. If the oil is relatively "clean" and mostly present in the sump and you have decent OCI records, I dont think they care, or, KNOW enough to care. Whaddya think?
I agree BUT...if under warranty you'll need records. So either you need to be straight up and be prepared for some discussion, or take the sneaky route which to me is an integrity issue so....
Most likely records that show the oil was changed in a timely manner is going to be more than enough, because the liklihood of any issues actually being oil related are very very small. JMO. But I'm still running thick 20's in our KIA.
