The dealer changes the oil for me and I only use shell gas on all my vehicles. I can notice the difference on my turbo vehicle

I don't think I worded my comment correctly.
My turbo teg I change the oil in it and I use valvoline 10w-30 oil in it when it's ready for synthetic. I just rebuilt the motor because I dropped a valve in the previous, I was revving to high. In my lex, gs 430 and is300, I have the dealer change those. Mainly because it cost the same for me to do it myself and they dispose the oil as well versus me storing it.

new battery is good news. your car will live longer once it receives one.
Don't do what I did. Drove my Audi A4 with its OEM battery to the point where if I stopped for 1 min and didn't turn the car back on within that minute, the battery would need a boost.

This in turn hurt my alternator. When I lock / unlock my doors you can see the door step lights and even headlamps being drained of energy / voltage.

Do the battery change sooner than later.

Plugs? Use OEM. I haven't done MAF or TB cleaning yet. I haven't had issues with the car so I'm not messing with it lol.

Also, completely agreed on the battery. Once you kill your batt, your alt is all the juice that's given to the car, making it prematurely die.

I have a 2006 GS430. I do 85% City driving and in hot Texas summers with AC on all the time. I usually get around 13.5 mpg running around town.

I've done all maintenance recently except for throttle body & MAF cleaning.

Well you don't need higher octane, but here in Toronto you can easily find 94 at a lot of Petro Canada stations if that kind of thing makes you feel better.
