Many use Mobil1 and some use Royal Purple, Motul, Liqui Moly, or Redline. A good thread to probably read up on is the blackstone UOA Analysis. That should give you an idea on what matters and what doesn't.

Castrol 5w-30 is it exactly. The IS-F of all years came from the factory with conventional 5w-30 oil, although branding may have changed. I used to be a firm believer in sticking with only synthetic, but Lexus would not be putting conventional oil in all of their cars if they did not have a reason to. For this reason I will only be taking it to the dealer for its oil services with the standard recommended oil (conventional).

Also forgot to add, in my experience, oil leaks seem to start occurring when you suddenly switch from conventional to synthetic.

I find this thread quite interesting.

Over this side of the pond, we have a different service level to you guys I believe? Ours is 10K miles or per annum.

I also checked with my local Lexus dealer just now, and they use Castrol Magnatec fully synthetic 5W-30 in the F's.

Just thought I would throw that out there to see what people think?

I'm wondering what the best oil would be for my F at the moment as well.

Just to add this is what I see when I enter all my details in a well known UK oil suppliers search engine: http://www.opieoils.co.uk/c-2355-loo...earFilter=2008

I like threads like these. Picks people's minds. It is certainly something else when different dealers recommend different oil brands. I had some service done on mine yesterday at NorthShore Lexus and the guy helping me said he has an '08 that comes in that is shy of 200k miles. I didn't even think to ask what they use for oil.

Q & A

To my knowledge they ship from Japan w/ Toyota 5w30 Motor Oil in them..

That even goes for todays 2016 GS F & RC F they build with the stronger iteration of the 2UR-GSE

Is it possible it's this stuff? http://www.eneos.us It's what I use.

But "Toyota" doesn't have their own brand oil "Toyota". Don't they hire "XYZ" to make motor oil specifically for the car? Like other poster stated that Toyota has never built anything like this before.

I've used Motul 8100 in the F, 300v in my ttZ06 and 300v in our race car. The one time I used Royal purple I actually spun a bearing in my motor.

His car wasn't running right, it turns out they put 5W-20 in there, not sure if they put enough either, you may want to ping him.

He also had his radiator cleaned out of some derbies that were there.

He switched over to RedLine 5W-30 and said the car runs much better.

Motul and Amsoil are good oils as well.
