Winter is coming and I wanna switch my oil with 0w20 synthetic instead of the recommended 5w20 semi-synthetic. I've did a search around the web and apparently the Honda Genuine 0w20 oil was a pretty good choice along with the earlier Toyota genuine 0w20 oil. Since Toyota doesn't have the same oil supplier as before am going toward picking up some 0w20 from Honda. Now the question is, will it void my warranty and is it the same as any other 0w20 oil or is it made specifically for Hondas? My Mazda 3 2010 engine's is a 2.0 FYI.
