Seems to have improved performance, hard to tell at the moment if it's any better than off the shelf oil as only done about 50 easy miles with it so far.

The best oil for hard worked engines, the peak temperature capabilities far exceeds the competition. Don't skip on oil!

when choosing engine oil it is a bit of a mine field out there. so many options from hundreds of different companies, with varying price points, claiming so many different benefits. so how do you choose a engine oil that is going to keep your engine spinning through thick and thin? well, i chose this oil over all others, why? its proven, time and time again, to be a great choice for boosted applications in the mx5 scene. if you read the description you can see there has been some serious science put into this engine oil to take all the guess work out for us, we just pour it in and reap the rewards! i will defiantly buy again!
