I've always used Royal Purple or RedLine in sports cars that I've owned. About to do my first oil change.

 

Amsoil signature series.
One of few company to have proven test results and data sheets of all their products.
Easy to buy online.

 

I did a lot of checks and I'm using Mobil 1 0W40 New Life - it's quite a good oil for decent price, I do mainly highway driving and change it every 12-13000 km (7500-8000 miles).

 

Previous owner told me he always ran Mobil 5w30, however, I'm a firm believer in Rotella T6 5w40 so I may switch to that when it comes time for a change.

 

Thanks to the advice of 2URGSE...I switched from dealership stock to Redline 5w-30.

 

Car seems to like Redline oil 5W-30. You can order it on Amazon or find a local dealer, it's usually not sold at the Auto parts store, although I've seen it on the shelf in some very rare occasions.

Now don't forget, this is 9.8 qrtz!

You will also need the filter removal tool.

 

I use Mobil one 5w-30, but I don't track my car so it probably doesn't matter much.

 

5w30 mobil 1.. I dont know why people putting thicker oil as they are doing more harm then good..

 

Use pennzoil platinum pure plus synthetic 5w30

 

Mobil 1 with the factory recommended viscosity.

 

Amsoil for me

 

i have always use purple royal 5w30 on my old is300 and on the F

I'm going to give the RL 5w30 a go. Lots of local parts stores stock it at $11 a quart

Care to explain the "Car seems to like" part of your post?

Thanks for the heads up on the Tool. Just ordered it.

 

Same here. It's what the Lexus dealership puts in here. I don't know about other dealerships though.
