mobil 1 synthetic for the eaton?

[TVSCobra]

Not me told him to leave it dry and I'd refill myself.



Contradicting info. right there. Read....use the supercharger oil for best results but you'll be ok with synthetic engine oil? oke: It's one or the other, either you chance blowing/leaking seals or you don't. Open/shut for me and why I use the required spec. oil.

Why is it that everyone wants the holy grail of lubriants for their motors, transmissions, and rear ends but is willing to cut corners with the blower to save $20? :shrug::??:

What I was getting at is that no one has reported oil related failures using synthetic engine oil. Just because an oil doesn't meet a certain spec, doesn't mean it will not work fine. Oil companies pick which specs they want their oils to be tested too. No condradicting info.

Cobracide, that all sounds great and all, and is certainly way beyond my knowledge of the inner oiling mechanisms of the Eaton 112 supercharger, but for whatever reason, the synthetic 30 weight motor oil that currently resides in thousands of these blowers is somehow working just fine. So fine in fact that the two companies (Posi Performance and Steigemeier Porting), that have been inside more of these blowers than any other entity, are confident that this lubrication approach is not a risk to their warranties of the thousands of the M-112's that they have ported over the years.

I personally have no animosity towards using supercharger oil in the M-112, nor is it a financial burden for me to do so. And I have 7 Ford and Chevy dealerships within 30 minutes of my house so it's certainly not an inconvenience for me to buy it. I use Mobil 1 synthetic oil in my eaton because there is no risk and it has been proven to be totally sufficient with the proper lubrication of the blower. This subject has been debated to death for years.

This.

Why supercharger oil?

At the belt-driven end there is a snout with two bearings in it and two gears. These depend on oil, a special oil formulated for superchargers. Supercharger oil is very fine because it has to get into some very small spaces to do its job.

In most parts of your car that need oil, the oil is pumped or slung to where it needs to be. For those applications, that’s fine. The supercharger snout is different. We can’t maintain the oil level up in the area of the seals on the rotor shafts because they can leak into the housing and the rotor group. So the correct oil level is about ¾” to 1” below the center of the lowest rotor shaft. That means the oil will sit lower than the lowest seal and bearing when the blower is not in operation. When the engine starts and the supercharger rotors begin to spin, the gears start slinging oil. Unfortunately, they cannot sling oil to the front of the snout. A simple slinging arrangement won’t be enough. That’s where supercharger oil comes in.

Supercharger oil is unique in that when it is stirred and slung it atomizes. The area inside the snout becomes filled with an oily fog that permeates all the way to the bearing at the front of the snout.

This is correct, but many have used synthetic engine oil and have had great results. I would use the supercharger oil but I change mine often. So Mobil 1 15w50 or Castrol TWS 10w-60 for me. Doesn't Kenne Bell and Whipple use a 50 weight engine oil? I also called and talked to Steige and he said my engine oil choice in the Eaton would do fine.

This will always go back and in every dept. Engine oil, Transmission oil, Rear end oil and the same results always occur many different thoughts and contradictions...Im an automotive technician and we are taught to use "OEM Spec" which is fine...but I always do different fluids with different applications! I just bought two bottles of the Ford supercharger fluid @$16 each from Tousley and whether it is better or not it came with the car and does its job! $30+ dollars on my car in maintenance is better then $100+s in repairs! just my .02cents

thanks guys i pulled the plug off, and tryd sucking some out and nothing came out, so i tryd to add and it took 5oz ? i take it i was low? the car has 25k miles

my tube was to big thats all i could get out at the time my bad

Nothing came out but 5 oz's went in so I was just saying it's worth checking because you literally only had 1 oz in your blower.

So does the Ford spec. motor oil, trans. fluid, and rear end fluid yet no one wants to use them and the forums are littered with "what's the best motor, trans., or rear end oil" threads. Just making an observation. :-D

IMHO putting synthetic motor oil in the blower and putting it on a regular oil change schedule would be better than someone going off the guideline that the factory stuff is good without changing it for 80,000+ miles. I'll say for sure by then you will not have 6 oz's left inside the blower. So 6 oz's of synthetic is better than the 1 oz posted above.:beer: Plus it's been proven to work perfectly fine. I can't recall how many people call and say they need a rebuild of their superchargers because it's making a "sound". I tell them first thing to do is check the oil level and either change it or top it off. I'd guess 99% of those never call back because I've ported 125+ blowers now and rebuilt less than 10. These blowers last for a very long time with no maintenance at all. Let alone just a little TLC.


Nothing against using it at all and it's up to each individual.:beer: If I could get supercharger oil cheap enough I'd put it in my Ports. I cannot though as of yet but I'm always looking.

I may consider this kit. It's GM sc oil. And comes with 8oz and a syringe.
