"Mark Skaife said to me up in Townsville last year that Adelaide will be a strange one for me, that I'll have a tingling feeling in my gut as that's when it will hit home.
"It's not exactly new news that I'm not driving full-time in 2019, but it'll be a strange experience.
"I got a taste of that when the test day was on at Phillip Island and I wasn't there.
"I'm at home with the live timing on, getting text messages from people, only having a little bit of an idea how it was all going... that was really strange.
"Just another former driver now, I guess!"
Lowndes won the very first Adelaide Supercars event in 1999
Lowndes joined Triple Eight in 2005 and stays on with the team this year to partner Jamie Whincup in the PIRTEK Enduro Cup.
He also remains an ambassador for the outfit, but rebuffed the notion he'll favour the Red Bull Holden Racing Team in his new role.
"Because I'm still driving for Triple Eight in the enduros with Jamie, there's been a little bit of chat on social media that I'll be too biased towards the team or Holden, but that's absolutely not going to be the case," he added.
"I'll call it as I see it. Like anyone else, if Jamie or Shane [van Gisbergen] do something good, I'll comment on it, and the same applies if they don't.
"If that involves those guys, or Davey [Reynolds] or Frosty (Mark Winterbottom) who's in Holden world now, then so be it. You have to read the play and tell it like it is.
"Because of the relationship with Jamie and Shane, it'll be good as I can go in there to the garage and ask them what's going on, which will be a handy thing... as long as they actually tell me!"
