Overall quieter, smoother running engine. With Mobil 1, the engine has this rattle sound, that I have concluded is related to the timing chain. Once I fill up with Motul, that noise is completely gone and this is 100% repeatable. I can switch back to Mobil and the noise instantly comes back. I am certain Motul provides better lubrication for this engine. It's not a coincidence. The engine revs smoother with Motul. That is a small difference but the timing chain noise is not. Power wise, I don't feel any major difference between the 2 and have no data to prove anything.

So if it works great in a mid engine trubo charged car, yeah it's going to work in ours.

Like I said above, I don't sense any power differences. The differences go way beyond power in my situation. Your MR2 doesn't have an FA20 engine. The same oil can behave differently in different engines and I have no doubts Mobil 1 worked well in your MR2.
