So I just got the letter today and I know my car have these problems like misfire n vibrating at stops but when my macanic check my car for codes he said its not showing anything. Last year I got service at dealer before my 70k they fix my valve n valve spring n the problem was gone for about 9 months n now it started to happened again. It seems like they didn't fix the problem. What show I do. Should I wait until it happen more n code my shows . It happened about 8 times already.

A few questions road rage since you are very well informed about this...when I went to lexus they told me I would have to wait 3 weeks cuz corporate will only allow them to do one of these jobs a week?? what is that about? Also, what fluids will they change during this repair? I'm assuming oil and coolant...anything else? Thanks

^^ No problem. I personally let them put regular oil in and then drove it 1k miles, just to break in the new parts. Then had them change the oil with Synthetic after. Not really something you have to do, but I just have seen others do it as break in maintenance after serious engine work so I figured why not

This repair isn't a new engine tho so its really up to you how you want to deal with it. I played it on the safe side and just went with regular oil like it came with off the line and then just changed it out at 1k miles to clear out any metal shavings or small debris that might exist from the break-in of the new parts.

I didn't know they would put regular oil in. I've always used Mobil 1 synthetic.
The new oil change sticker says 5000 miles until the next oil change. I wonder if it is synthetic?

That's a debate on its own. Some think regular dino is best, others argue synthetic is best for breaking in a motor. Some cars come off the line with dino oil, others roll off the line with synthetic. For the 06-10 ISx50 they are factory filled with regular dino. I believe '11+ IS250's are filled with synthetic now and '11+ IS350's are dino if I remember correctly. Most modern engines are broken in before being delivered now anyways.

Breaking in a Lexus engine is not something very important. It would be best to avoid high rpm and load for the first 1000 miles, but it's honestly not very critical.
You're fine with conventional, synthetic blend, or synthetic oils. the engines react the same to all of them. of course the difference is how long they last.
there also is no particular break in oil. that goes back to the days of cast iron piston rings and flat tappet camshafts that are under ridiculous pressure. Engine design has changed a lot over the years. some things (like wear) are not really a concern anymore. they've just managed to create some new concerns.....like carbon.
