Just ordered a quart of Mobil Jet Oil II. 'Slownrusty' hope you drained that clear oil back out and put the one needed back in!

putting the Screw back on did you guy use plumbers Teflon tape?

taurran

I did.

Just replaced my oil. I feel like I still "taste" that horrid barnyard smell. I ended up only getting about a quarter of a cup out, and filled in 150ml. I gotta say the hardest part was putting that screw back in.

That damn screw, I used a flex magnet and a a lot of beer. 20 minutes to get it back in!!!
On a good note my brake fluid bleeder removed all the oil.

Did you use a "ball head" allen wrench?

thunderclaps

No I use a regular Allen wrench. Luckily it wasn't to tight because I use a size smaller to compensate the angle.

AgSilver

I had no problem using a ball head. well . . . next time, right?

went to do mine last week and found the drain had no screw on it! was booked in for a dealership service so left it til today.

the tech said that the sc is a sealed unit and fluid can not be added? aso said there is not meant to be a bolt there?

i've had the car 2 years and the sc works fine.

mines a late 2002 model, any clues?

guess mine's past due...

Same here, ball head allen wrench works just fine. Just filled mine up last week.

There was this guy who fell off the top of a tall building . . . and everybody on the various floors could hear him say all the way down: "so far so good, so far so good."

AMG013

I know it sounds ridiculous, I guess i'll stick a siphon/hose up there and see if anything comes out (sounds dirty!).

But you'd think a dealership tech knows what they are talking about, also they noted my concern and their response on the service record so if the sc does blow due to low oil, that would hold them liable, at least in part...

I a way, the tech is partially correct. As far as MB is concerned, it is not a serviced fluid. It "should" last the life of the vehicle. That's why the fluid for v6/v8 kompressor cars is not directly available from MB.

For me, as a MB master tech that just picked up a 04 E55 I'm going to change the fluid in mine. No oil lasts forever and no seal seals perfectly so it's cheap insurance. As a side note though, I " personally" have never seen a supercharger fail from normal use. I think there may of been a couple of forum members that have had rotor bearings fail, but I don't know what led to that. Higher than stock supercharger rpm I'm sure doesn't help.

AMG013

Well if it's good enough for a master tech, it's good enough for me thanks!

Whats you thoughts on evaporation as discussed in similar threads? put back in the volume that comes out or put in 125ml/cc regardless of what comes out?

On a separate note, the can of jet oil 2 I picked up has an expiry date of 2017, I guess thats a tell tale sign that the oil does not last forever. Just a thought.

When the first 722.xxx transmissions went into service, MB stated that they never needed fluid replacement. After having to replace a great many 722's, MB rethought their position.

I was calling around this afternoon to see if I could locate a quart of Jet Oil II. Well, I found some at a local aviation repair facility ($25/qt) and for grins I thought I would try the local dealership also (Tysinger Mercedes in Hampton, Va.) - just in case they had it cheaper (i knew better). I spoke to the parts dept and they had to ask a technician about it. According to their "certified tech" there is NO OIL in the supercharger! Oh, and they were really curious where I got my information! Like the saying goes, if you want something done right...

Capn

Guys, have you noticed any different with the performance on the supercharger after replacing the fluid?

pmgiarrizzo

This is the exact question i posted today. No one has seemed to read this man's post. Everyone skipped right passed it.

If anyone has used the Jet oil 254 vs the Jet oil 2 please post differences or info about it that you recieved. I am expecting a phone call later today from www.airplaneoil.com and hopefully i can post my own information according to them.


but until them, type away!
Pete.

Perhaps no one knows what the difference is so they refrained from speculation? We look forward to your findings!

When refilling, does the supercharger need to be level to the ground? ie: should I jack up the back of the car to get it level?

pmgiarrizzo

hey guys,

I posted a new thread regarding supercharger oils etc. hopefully its enough information with respect to choosing the right oil.

as for the car being level. if your car is at stock ride height, put the car on some level (or as level as you can find) ground, take the 5mm allen plug out, use a syringe with a hose attached to it to suck out the old fluid. it might be easier to do this if you had the car warmed up for about 5 min. the oil should be more free flowing.

once you have sucked out "all" of it (or as much as you can get). replace it with new fluid until it just starts to seep out of the plug. that is a 3 in 1 plug. its a drain plug, a fill plug and a level indicator.

here's the link to the supercharger oil info i made:

hope the info helps!

YES jack up the rear so the supercharger is level. This is the trick that most everyone misses that guarantees correct level without guesswork. This way the drain plug can be used as a leveler for the correct 150-165ml of oil. Just make sure you tuck some paper or rags under the plug hole first.

Denroll

If you ever have to pull the supercharger for anything, that would be the best time to change the oil. You can tilt it over and let gravity do the draining for you, then move it around a bit to get it out of any nooks and crannies. You can even take it outside so you don't stink up your garage with the old oil. Place it on a level work bench when filling and it's a piece of cake. No fussing with the bolt at a weird angle.

BagMan

Thanks guys!

I'd actually like to pull the S/C so I can install the meth kit, but I haven't found a great DIY - I've just been kicking that can down the road.

The car has been keeping me busy with repairs lately.
