Engine oil MOTUL or Pentosin

That’s why I use MOTUL

The Motul would be my choice. With your temperatures its the best optione between them.

La seconda. Motul.

ns 400z will be good with motul engine oil and iridium spark plug avoid bajaj oil

Motul 8100 power 5w-40. Best oil in my opinion. Great if you run ethanol

Was running cheap ass liqui moly but now that I\u2019m not slow stock turbo anymore i run Motul 8100 Xclean (5w-40).

I try and stick with Motul 10W60. But I don’t think the engines are particularly picky about brand

Have it in my N55 and it's very happy.

I recently switched to fully synthetic motul 7100 10w50 too, which did help a little, but didn't solve the issue.

Don\u2019t buy the xcess version. Causes weird engine deposits. Stick with xclean.
