Hi all,

I've reviewed several posts and can't quite find a specific answers. Very happy with my purchase, but had a few questions about scheduled maintenance. I've checked the Lexus service history on the car, a 30K maintenance was done approximately 2 years ago. However I know for fact the car has been baking in a South Florida car lot since July. Driven about 90 miles til now, scheduled maintenance is basic at this point according to the Lexus website, however I'm concerned about the majority of fluids have 8 years on them. I'll be honest I'm tempted to do a brake fluid flush, a transmission fluid change, an oil change, coolant flush, and maybe a fuel additive and blow it out on the highway. I know the long life coolant is good til 100K but 8 years seems high. Overkill?

Of course there is a scheduled maintenance schedule, but I don't see a reason why you can't just do what you want.

I have a "Florida car" which I bought used a couple years ago, when I drained the tranny fluid it was very dark. I attribute that to the Florida heat. Tranny fluid doesn't like heat, I imagine your fluid has probably gotten hot, but then again you only have 30 something thousand miles, I had 74k miles. Same probably holds true with the coolant...it's been worked and it's 8 years old. I want to say the life of the coolant is 10 years 100k, but it might be 150k. I changed mine out at 80k.

The brake fluid should be flushed at around 35k miles anyway, so don't feel like you're wasting your money there. As for fuel additives? In my opinion they are bogus, junk, scams, wastes of money, psychological pleasers with fancy bottles and empty promises. There are some decent videos on YouTube by a guy named Chrisfix - he does some pretty involved studies on the before and after results from every fuel additive/intake cleaner known to man....the results are laughable. And this guy tests everything...Techron, Seafoam, Lucas, STP, the new stuff, the old stuff. It's all basically the same...little to nothing. And keep in mind your car does have direct injection, that's some high fuel pressure...chances are it doesn't need to be blow out on the highway...it already has pressure pushing into those cylinders.

But I always go by the motto, if it makes you feel good do it. Heck change the rear end fluid...what will that cost you? 20 bucks? I've done it twice already.

I only saw two of the 38 thousand questions.

Lol! Very nice.

Doublebase has you covered. I would add: if it's AWD go ahead and service the transfer case. Do your research on it and use the recommended fluids in the differential and transfer case. In the transmission I suggest Toyota WS only (nothing else). The service is not easy, it can be a DIY.

Many of the fuel additives are lack luster, but I like the Royal Purple fuel system cleaner & its $10-12 at Walmart. If you try it let us know what u think.

If it were my car, I would do all the services you listed.....ESPECIALLY the brake fluid. Brake fluid is hygroscopic and sitting for so long in a humid environment doesn't help. DO NOT do this yourself. Your Toyota dealer can do it for you (I paid 79.99) and they use Techstream to do it, which is the proper way in order to avoid brake system errors. Coolant drain and fill is definitely an easy DIY as are oil changes and diff fluid changes.
