Since my car's too low and i don't have the place to do oil changes anymore...

Thinking about picking one up from go fast lab.

 

I have one and have used it for Clutch and Brake bleeding. It works like a champ in this configuration. On the other hand I have never attempted to use it for motor oil extraction.

 

For brake bleeding, did you extract the fluid with the pump straight from the bleed valve(one man Job)? Or did you just use it to catch the brake fluid?

Thanks for the input.

 

I extracted the brake fluid using the pump itself. Works like a champ doing it by yourself.

 

I'm thinking you're a bit confused as to what the motive bleeder does. At least the one I have, is basically a weed sprayer with a gauge and a quick disconnect fitting on it. You pump it full of air, and the pressure drives brake fluid out thru the fitting and into the adapter which attaches to your brake fluid reservoir. You are effectively pressurizing the brake system, so when you open each bleed nipple some brake fluid will be driven out, bleeding the system.

The nice thing about the Motive bleeder is that it constantly keeps the reservoir full of fluid, so you never risk running low and driving air into the master cylinder. The bad thing is that the universal fit adapter for cars with non-threaded reservoir caps is pretty hokey. It works better on German cars with threaded reservoir caps IMHO.

Also, this thing works fine for routine bleeds, but I found that when a system has lots of air in it (brake line swaps etc), the old fashioned 2 man pedal pump method works better for driving big pockets of air out.

I have no idea how you would use this for oil changes. There is a different kind of extractor, such as the TopSider or equivalent from Griots. Instead of generating pressure, the pumps in these work in reverse to generate a vacuum, which can then be used to suck oil out the dipstick tube. I used one of these as well before, but a friend theorized that they can be less effective at flushing sludge than draining out the bottom hole.

Nevermind, just looked at GFL and realized they make an extractor as well as a power bleeder, which was what I was talking about.

No experience using these for brake flushing. Comments about extracting oil with TopSider still apply as this is a similar device. It is convenient I guess, but on a car like the S2000 in which the filter cannot be accessed from the top, I'd rather just drain it out the bottom. On my Z3 at least it saved time because the filter could be changed from the top so the car could stay on the ground.

I just changed the filter on my bone stock S2000 from above this past weekend. With the Fumoto valve, I can do the entire oil change from above.

 

I have MityVac fluid extractor, it works very well for Mercedes because all newer MB cars are designed to use vacumm to extract engine oil. I tried that MityVac to do oil changes for LS400 and S2000, it is difficult to extract all old oil out of either cars, because the end of the dipstick tube of either car is not at the bottom of the oil pan. I had to adjust the vacumm tube several times to be able to get all old oil out.
