I have been using the Mobile 1 0W20 for oil changes due to its availability and cost. During my most recent oil change @ 38,289 I decided to go back to the the Toyota 0W20 oil. Once I started the engine after changing the oil I immediately noticed a much quieter engine (much less valve train noise). Has anyone tried or noticed the same? I sent that last batch of used Mobile 1 0W20 to Blackstone for a report and will do the same once the same number of miles is put on the Toyota 0W20 to see if there are any substantial differences.
