The initial seat of the pants feel is stronger and smoother engine response. My car has 99,000 miles.
This is not hard to do. Just time consuming. The oil vacuumed out did not smell or look as bad as many have reported.
This something all S/C engines will benefit from. Hopefully this add a couple years to the life of the blower.

 

This is my project next week while I'm off. I was going to use a turkey baster with a hose to extract/fill the S/C.


What did you use?

 

Bought off Amazon. Mine vacuums and pumps. Think it holds 3 gallons.
Use it for oil changes and flushing power steering. Pulling 6 oz of old oil took 15 minutes. The WD-40 straw is a real restriction.
The positive of a Miteyvac is inserting the straw, pump it 10 -15 times. Then listen for it to suck air. Then move hose until it sucks fluid again.
