Maintenance questions for IS350

I have a question about oil change. The Lexus oil change sticker says I'm due for an oil change but the car doesn't indicate that I should. So should I go off the car warning light or the sticker?
Last time I brought my car in according to the sticker and the service rep told me I don't need an oil change yet because the car didn't indicate it. Not sure if I can totally trust service reps hehe.

Isn't Kurtz and Koz response contradicting each other?
So what I gather is basically I can wait till the "required soon" light comes on and then get it changed soon afterwards.
Also what is OCI and UOAs?

What you actually need to do on a 2IS:
Oil changes as appropriate (probably 1/yr for synthetic, 2/yr for conventional)
Every 15k: Change air and cabin filters- You should be doing this yourself, it takes 5 minutes.
Every 30k: Change brake fluid
Every 60k: Change spark plugs
Every 100k: Change coolant
That's -it-
That's also why you should never ask a dealer for the "X miles" service- they'll do as above plus jack the price up 3x higher for a bunch of "inspections" that they'll do for free anyway if you just have the stuff you actually need done.
Completely false. Federal law prohibits them denying warranty coverage for anything you do aftermarket unless they _prove_ that what you did causes the failure.
Which won't be the case with 1 year changes using a good synthetic.
Amsoil in fact -guarantees- their oil is good for 1 year/25k miles.

Where in my post did I say anything about them denying warranty coverage for doing something aftermarket? Please read it again.

OCI = Oil Change Interval
UOA = Used Oil Analysis

From what I've seen, experienced and read I would recommend maintenance as follows;
Dino oil and filter - Every 8K miles or 1 year (Which ever comes first) I don't even use dino oil in my lawnmower
Synthetic oil and filter - Every 15K miles or 1 year (Which ever comes first) Group 4 oil only (Amsoil 0w-30 or 20)
Diffs - 1 time to a quality synthetic (Amsoil Severe 75-90)
Auto Trans - Don't touch
Anti-freeze - Every 4/5 years with quality Extended life fluid (OEM is good stuff)
Brake fluid - Every 30K miles (Use the best fluid you can find within OEM spec)
Air Filter - Change to Cotton/oil filter and clean every 20K miles
Spark Plugs - Every 50/60K miles (Use OEM NGKs)
Front brake pads - Every 25K miles (Use the OEM dustless)
Rear brake pads and tires (As needed) NEVER summer tires!
Replace all bulbs to LEDs (except headlight and vanity mirror)
Change shocks to coil-overs ASAP (When money is available)
I avoid mods like lowering and bigger diameter wheels.

Coil overs are not just for lowering the car. Better handling, above 100mph the suspension is not as tight as I would like. Regardless of what most people say, lowering and bigger diameter wheels will only have a negitive affect on the street.

Yes, and in this case Kurtz is right. The warning is based strictly on mileage: the "Oil Maintenance soon" warning is displayed for a few seconds after starting the car from 4,500 to 4,999 miles after the last reset, and the "Oil Maintenance required" with the bright exclamation point is display full time when you pass 5,000 miles after reset.
Doing so will give you the (nominally) 5,000 mile oil change interval prescribed in the owners manual.
So what I gather is basically I can wait till the "required soon" light comes on and then get it changed soon afterwards.
