Default RX450h+ need high test gas?

I am contemplating the purchase of a plug-in RX and see that it requires premium fuel. Has anyone used regular? Does it hurt anything? When I purchased my first Lexus it said it needed premium and I always used premium, but later was told it wasn't absolutely necessary. What is your experience?

91 is recommended with 87 being the minimal. There are tons of posts regarding this and a lot of people are using regular without issues.

Premium recommended, but you can use regular. This is according to the manual.

I have yet to put any in ours yet since it's new, but I am gonna probably just split it and do 89 LOL In Jersey, it's $1 more for 91 vs 87 and only about .20 more for 89
