Low coolant on ‘25 IS 350 AWD

I have low coolant on my ‘25 IS 350 f sport awd.
A few months ago it was at the low mark so I know it’s loosing coolant.
I do park on a decline but even then it’s not making that much of a difference.
No leaks or anything like that.

I have 2 questions:
Can I just buy OEM coolant in that reservoir and be good? Or will I need to burp the system since I introduced air into the system?

2nd can I just take it to the dealer and have them top it off free of charge?

Quick question,
I have a ‘25 IS 350 f sport awd and wanted to know what’s the best lca bushing, RC-F or RR racing Street?

I heard the rr racing sequel during the colder months, have to be regressed occasionally and they could possibly increase NVH compared to RC-F bushing.

I want something that will help with the inner tire wear but don’t know which would be better your opinions would be great at which I should get.

I have a ‘25 Is350 I don’t need a battery right now but I would like to be prepared for when it happens.

I’m not known for good luck with batteries on vehicles.

Does it matter if I get a group 24(F) or 34 battery or can I get whatever?

I usually get my batteries from Sam’s Club the Duracell brand but I have seen the reviews for those batteries and they seem to not last past 2 years.

Would AutoZone, Advanced Auto or Walmart be a better option? I do not live near a Costco, BJ’s, o’reillys, NAPA.

Also can I use a maintenance free Lead acid or AGM battery and be ok as long as it’s at or above 580 CCA?

Would having 700-800 CCA cause over charging issues?

Last Question how do I maintain a Lead Acid battery like the one that came from the factory in my is now?

Sorry for all the questions.
