I use Redline 5w-40. 0w-40 will give a tad more power (tad more, you'll not feel it). Considering the Engine is made by Toyota and a Yamaha design and Lotus have not done anything to it at all mechanically, I have no idea why anyone would ask Lotus what oil to use -- suggest you contact Toyota.

I've had good success with Redline in various cars - $8/qt with 2000-3000 mi between changes. I can't say Redline is better than any other oil even non-synthetics, I just have no real world evidence that has shown Redline $8/qt to be better than Penzoil $2/qt. I've never had an engine failure that can be attributed to poor quality oil, and I've never ran an engine beyond 60K miles before I've rebuilt or replaced it.

But like I said, ask Toyota not Lotus.
