Supercharger oil

[ScottinMA]

I have one of the early Alpine SC and would like to change out the oil. Has anyone done this in the last year or two that might share the location of the fill plug and what type of oil should be used?

Many thanks

Hi Scott,
The fill plug is in the front. It is an allen plug with o-ring, so no need to over tighten. I use GM supercharger oil. GM uses the Eaton S/C on many models. I use a large syringe with a clear hose of about 1/8" inside diameter. I extract by putting about 3" of hose into the gear case and filling the syringe. I keep slurping until I can get no more. I fill the same way with out the hose on the syringe. I fill to about 1/4" below the fill hole bottom. I fill until the oil comes out and then extract back to 1/4" down. If you fill more, you will force oil out the front and you will see it collecting in the gear case cover bolt recesses.
Cheers, Roy

Roy,

Thank you! That's my plan for this weekend. So far, replaced timing belt, both front and rear brakes and rotors, tranny fluids, diffs, transfer all with synthetics, new belts, plugs, alignment, front wheel bearings repack, and I'm considering the radiator next.
