Dont make fun of me for asking this guy`s
,but supposedly I can use 5W20 oil in my RX according to the Toyota oil chart. My question is, would I be better off going to PYB 5W20, or Ultra/Mobil-1 5W20? It has 88k on it and no consumption,just thinking about trying it. Actually tig1 made me think about this because he did this years ago with good results.
