Use 5w40 oil and change every 3-5k miles, modify the tstat, remove the active shutters, high flow exhaust, wrap the coolant tank in heat tape. The engine will certainly last longer with these mods.
Great video ! I was looking into the m850 with the TU3 but it seems that no matter how many modifications they make it still is a high maintenance motor.
Thats incorrect ! They are extremely reliable engines if you get one that wasn't trashed and do regular oil changes - Its a shame people tune these cars to 800+ HP blow they engines than say they not reliable
Yes, the N63TU3 is less reliable than a Toyota Yaris engine ! Let's be fair and understand why the engines are made into a hot V and all benefits attached to it. Comparing the original S63 to a newer TU3 is like comparing day and night in regard to reliability. Of course it's gonna be less reliable than a non hot V engine since the heat generated is completely different when turbos are mounted on the outside.
