Going with Motul engine oil...
 

Summer is here and is bloody hot. I will use Motul engine (5W/30) oil in this interval, my concern is which Motul i should use:
Eco-lite
Eco-nergy
X-clean

x-clean

Just use a good 0W20. I know you think a thicker oil will not break down with the heat. But a thicker oil may also not circulate as well and could retain heat. Assuming its a DD. Tracking is a different story.

Interesting about 0w/20. In Africa manuals says go with 5w/30 and where i live the temp is very similar

Hence get a good oil. There are 5W30 that will shear down to 20 weights pretty quick. Go to Bob is the oil guy and pick a good 0W20 or 5W30.

I use a thicker oil in my WRX but that has a turbo, that is oil cooled. The BRZ engine was built for 0W20, see no reason why a good 0W20 oil would degrade just because its hot out.

Doubt you are spending all day up at 7K rpm anyway. With normal driving under 4K the engine is barely getting a workout.

Thanks mate, i appreciate. Anything wrong about going motul x-clean?

I went with eco-lite 5w-30. It's energy conserving approved so it meets the energy savings requirement in the manual. No idea what that means.

They meet different standards so maybe that can help you decide.

Motul X-clean is good.

300V

Would you recommend 300v even for a daily driver?

Yes, I use it in my daily. You can run extended oil change intervals, but use used oil analysis to determine what is right for you.

Would you recommend 0w20 or 5w30?

I would go 0W20 if its a DD.

0W20
