Is it necessary to change the supercharger oil and if so how do we go about doing the oil change?

Triman2008

Here you go. Pretty simple.......stuff stinks though so be aware of that. Good luck.

Do you know what the torque spec of the drain/seal plug is?

About how much oil did you extract/ replace?

What mile/age was your car?

NB: I looked into it and was advised to use the Mobil Jet II oil you used and not the 254. They have some different characteristics.

This is a good video! Only change I would suggest is to refill the s/c reservoir until the Mobil Jet II oil just starts to overflow out of the fill hole. Same concept as refilling a differential. When I changed the s/c oil for the first time (~70k miles), I was able to remove very little fluid, even moving the syringe tube around with the s/c. But the reservoir accepted far more.

I ahven't done mine yet, but I need to. Looks like a straight forward service. Just like MB-Dude said. Fill it like a differential, till it over flows a little bit. I would use some lock-tite on the s/c hex nut. Just to make sure it doesn't come out. Not sure on the torque specs, but snug is always good.

MB-Dude

Triman - My experience is the hex nut is snug enough. I haven't used Loc-Tite on it, though it wouldn't hurt. I had zero seepage without it. I really encourage every s/c owner to do this simple maintenance periodically. Most logical question... How often? Not sure, but 30k seems reasonable, especially considering the simplicity.

When I do mine I will breaK it with my torque wrench and report back.

After a successful engine oil change on my G500 with my Mityvac I am ready to hook up the sucker!

And get a syringe from the vet.

I know this is off topic but, what intakes are you running? Did wrapping the tube help with keeping the heat out? I know they are suppose to keep the heat in when talking about exhaust.

Triman2008

It's not my car, it's another members car. The heat wrap does help with your IAT's. I don't know much, or what the stuff is that they used.

Great review on the SC fluid change with the youtube video. I did one for the STR Jag's SC fluid change on their forum. I just recently bought a s55 and was wondering where did you source out those specific led fog lights on the bottom fender? Those look really tight!

sorry for the bump, awesome video, having trouble finding a tool to remove the hex nut, the space is so tight...any suggestions without moving the pulley?

I had the car examined by an engine builder who builds custom blown engines for Fuel Dragsters, Funny cars and the like. In his shop there are engines and superchargers of all varieties.

His advice was NOT to change the oil on the S/C at this time (50k miles/ 7 years). He said I am running it at about 10-15% of the stress loads it is designed to take. However, if I was drag racing it on a regular basis, he would recommend a more frequent change interval.

MB-Dude

Grane - Refer to my 3/3/13 post. My s/c had very little oil in the reservoir; about a tablespoon, maybe two. I'm sure the MB s/c is under utilized, but since there is no way of telling lubricant level in the s/c, other than this method, changing the fluid wouldn't be a bad thing. I acknowledge his s/c experience thinking the oil doesn't need to changed, but my experience is the oil comes out heavily loaded with crud and of less volume. IMHO

Jeff, I certainly agree it would not hurt to change the oil on the schedule you are following. My engine builder did listen to the s/c and gave it a clean bill of health. I may just have the oil changed for peace of mind. Again if I was regularly tracking or dragging the car I would have it replaced more often, no doubt.

OP have complained about the smell of used s/c oil. When I had my Racing Brakes (fantastic product) installed on my CL, the tech used a special synthetic (blue) lubricant on the wheel hubs etc. as recommended after fully cleaning them. It smelled like cat **** right out of the jar!
