My F10 M5's engine seized w / 70k miles

[E93M3ofSFL]

So finally found a tow truck so my M5 is on the way to Troy Jeup up in Michigan ...

Can't wait to get car back now

Awesome, keep us updated. I guess once he does a full diag, you'll decide what you plan to do?

Did Troy say most of the seized engines are earlier pre-LCI models or did he not specify?

He did not specify but getting calls on this issue of engine failure every other day ...

It's a real problem for these cars ...

It can happen to lci or a 'pre lci no difference, same engines.Treatment in the early years is the key to engine longevity and using 'synthetic technology' oil is a no.Only full synthetic will do.

According to Troy using 5w50 full synthetic redline is the best plus changing thermostat also helps by lowering engine operating temperature which is too hot on these engines ...

What oil and grade was being used in your engine prior to it failing.

Whatever bmw dealer was using , I think it was the 0w40 Synthetic they use which down here in florida hot weather must become like water ...

Apparently the BMW 0W-30 is Shell Helix Ultra which is fully synthetic I understood that you said BMW Oil wasn't fully synthetic

Can you elaborate?

I can tell you now using that engine weight will guarantee another engine failure . Another OP dicing with his engine because a rebuilder told him its ok !

The maximum oil weight is 40W for very good reasons ! The S63tu engine has been designed internally specifically for a strict (criteria) weight oils . And that’s from Bmw M Engineers in Germany .

Another OP (from Egypt) on here tried 10W-60 and that engine failed (catastrophically) within 500-1000 miles after rebuild.

The best thing you can do with these engines is to change engine oil and filter on a regular basis .

I’m afraid what you’ve been told is well not true ! But don’t take my word and seek out an independent specialist Bmw engine builder .

I was referring to the 'synthetic technology' used in a description of that particular oil which to me meant a part synthetic one.Now on more intricate examination it is indeed a full synthetic and I stand corrected.

I am just happy that I am using the right oil and am doing as much as possible to have mechanical sympathy for its well being

Oil and filter change at 1269 miles
Oil and filter change at 7800 miles
Oil and filter change at 13800 miles

Your all good with that.My one gets changed around 5000 miles or every year whichever comes first,I'm at 34000 mi.

Nice to see a turbo blanket being used. Keep those temps down.

On the way to Michigan !!

This is what Troy Jeup claims

[induc916]

Is he upgrading your rods and pistons?

Yes ,

He is making engine bulletproof as he says , i don't race nor abuse my car but I tell you is a far better option than swapping with a used engine and wait for same thing to happen ... his prices are very fair ...

He offers an option with 850hp but clutch would suffer a lot with it so I decided to go conservative...

For everyone else whatever Troy is saying I would listen in one ear and out the other. He's in the business of rebuilding engines of course he gonna say that. That's his income and his job. He's a salesperson just as much as a engine builder.

Exactly.

I like Troy's work and I know he uses premium bearings and other parts (like ARP bolts) on his motors. Amongst all of the BMW approved oil viscosities, I certainly believe in the premise of using a 5w-40 for better protection for the bearings and turbos, so who knows, maybe he's on to something. He's certainly seen wear and failure on the internals of these M motors more than most people.

In Tasos Moschatos YouTube videos rebuilding an S63 motor, he shows you what the bearings look like on that motor and even says something like, "I don't know what oil you're using but if you continue to use it, your bearings were going to fail." One thing I have picked up from the BITOG forums is that HTHS is a better metric for comparing motor oils, and with the push by BMW to go with this new CARB/EPA friendly "FE" (stands for Fuel Efficiency) 0w-30 BMW LL-01 FE, the HTHS is supposed to be ≥ 3.0, whereas LL-01/04 call for ≥ 3.5 HTHS. The LL-01 FE HTHS is just too low, IMO, and is more interested in a small gain in fuel economy than the bearings in your M motor. Most LL-01/04 5w-40's will be in the high 3 HTHS but RL's 5w-40 are in the low to mid 4's. RL's 5w-50 is a stout 5.0 HTHS. Both Ravenol and RL have excellent Noack (volatility) numbers, so both are excellent oils for DI motors, especially our Turbocharged Valvetronic Direct Injection (TVDI) S63's.

I'm running Ravenol VollSynth Turbo (VST) 5w-40 right now but am considering maybe going to LL-04 and running Ravenol's Racing RUP 5w-40 next. EPA Tier 3 regs that began to take effect in 01.01.17 reduced the amount of sulphur in US petrol/gasoline to the same EU levels that BMW says LL-04 is approved for on Petrol engines there. I use Red Line's Complete Fuel System cleaner SI-1 with every fill, and I've considered using their 5w-40, as well.

[bruiser135msport]

Again I state that a 50W oil will guarantee failure of a S63tu engine and the Engine Builder stating it’s ok is in Australian parlance talking “crap”.

Their are very fine tolerances inside the S63tu engine and these engines generate a lot of heat .
Oil must flow internally when the engine is cold and hot (and that is why they recommend absolute limits on engine oil weights).

Just what mechanical engineering basis does he come to that conclusion or is it just a thought bubble !

Bmw M Engineers now more about this topic then me and frankly I’d like to see how long these engines last after “false Instagram advice” !

Bmw M engineers and Bmw M bean counters are two totally different people. You'll get two different answers as well.

[Craze]

Bmw engineers specify oil weight

Bmw bean counters make the parts not as durable for cost and profit reasons
