On my 8 month old 2020 Lexus ES 350. Only has 2300 miles so I am not in a big hurry. Just checked the OM and the only spec is 0w20 ILDAC Gl-5 which of course has already been superseded by GL-6A. I thought the FF was full synthetic, but to be honest, reading through these threads has be totally confused. I was planning to use M1 EP because that is what I have around for my 2010 MDX. I assume this is more than good enough, right?
