GM M90 Eaton Supercharger Oil?

Question

Hi
Can you put a synthetic oil additive ( Like LUCAS) in GM supercharger oil when you change it?
The M90 Eaton holds 8 oz and I was thinking about subbing in 1 oz Lucas Full synthetic oil stabilizer.

What is your thoughts or experinences?

Thanks

Answer 1

The GM oil that goes in that supercharger is 100% synthetic. And honestly it seems to do the job perfectly. Adding the additive might be a waste of time and money.

The lucas oil additive helps reduces fiction and increases the oil life at least by 50% they claim. With your blower...it's other things you should worry instead of friction and oil life.

The problem with the type of supercharger that you have is that there is a little coupler inside of it that usually gets worn down. And once the coupler gets worn down it will contaminate the oil. Once the oil is contaminated it usually soaks into the bearings and breaks them down. From the excess play in the shaft from the worn down bearings and coupler, it will wear down the seals and oil will start leaking from the seals.

Your best is not to waste your time on the additive, but to change the oil regularly in the supercharger. If you keep clean oil in the supercharger you don't have to worry about contaminating the bearings.

Now if you can find a product out there that will keep the oil fresh...then I think that would be the better way to go. But this is the real world...so regular oil changes will be the best direction to go. =)

The list of parts you'll need is long and expensive.First you'll need to see if anyone makes an intake and an intercooler for your supercharger that will bolt up to your engine.If your'e lucky enough to find that you'll also need to upgrade your fuel pump(more air,more fuel)upgrade your injectors(again more air more fuel)the wiring harness w/ all the sensors,upgrade your computer and all the misc. parts,brackets,headers and other little pieces that will make your swap work.After you get your s/c installed,you'll then need to take it to a professional tuner that will "tune"your ride as to take complete advantage of your newly installed blower.You tune your engines computer so you dont leave pieces all over the street.A good tuner that knows what he's doing will run you at least $1,000.00,probably closer to $1,500.00.If you want to go fast and not spend your kids college $$,get you a good used 4.6 from a wrecked GT.Strip out everything from it,engine,trans,harness,sensors etc.and drop it your car.Many people have done this mod,parts for the 4.6 are all over the place,you can find parts lists and other info on Mustang websites.This is a much less expensive way to go and you'll double your hp simply by going to V-8.Check it out,good luck.

I don't see where you should have any problems with that additive.
I have never had anyone ask that before.
I have had experience with Lucas products but had not thought of that.
