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.

@@alexstromberg7696 Up to and including Group III oil is Hydrocracked with Petroleum base oils made with extreme heat and pressure. Group IV is PAO which is man made. If you looked at oil as Ball Bearings the Petro base would be Ball Bearings of all different sizes. The true Syn oil Group IV is Ball Bearings all the exact same size. Big step forward. This is a large advantage bc they can take extreme cold and heat much better. They create the Wedge between highly loaded surfaces like Cam and Followers, Rod and Main Bearings. "No oil is 100% group 4 either." It starts out with PAO base stock so that's the advantage but if you mean the AP(Additive Package) is different one to another then agreed, that will be different. Mobil 1 was in trouble some time back bc they advertised as a Full Syn when it was Group III Hydrocracked and they had to change it. They stepped up to PAO and kept the Full Syn label. Some things change and if I'm off let me know but this is what I've picked up over the decades.
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
@@dnl35projects I heard full throttle every so often on the m850i helps with reliability? What's your thoughts on that? I know it can help with carbon buildup but not sure if these engines are prone to that
@@justcruising6824If you are thinking of carbon build up on intake valves? no this engine doesnt suffer from that, but every engine is prone to some sort of build up if it only sits at your regular rpm over time
In case of M550i is it ok to go with TU2 or better add some money and get the TU3? Or the TU3 updates are not so crucial in comparison with TU2? (Both bad? :) )
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.
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.
Cool updates, I'd use a Group IV synthetic or better. IMHO

MBZ/PORSCHE also produce Hot V engines....so is it really a bad idea?
GRATITUDE!!!
I didn't get what bmw tried to reduce in their multiple improvements of this engine. Maybe oil consumption but im not sure 😅
Awesome video!
Thank you!
Which BMWs have the N63TU2 vs N63TU3?
I believe that the 2017-2020 M550i has N63TU2 and the 2020+ version has N63TU3
Cheapest n63tu2 you can get is the 2016 bmw 750
You misspell "Degradations"
