oil changes?
from another Wayne (I think
)But that is a good call about using shops that have pits for radically lowered cars.

Ian, I used to use a vacuum pump to extract the oil on my V8 marine I/O engines. It was easier but I was never satisfied it was getting all the crud from the bottom of the pan. I got rid of it and went back to conventional oil changes on those engines even though it was very awkward and you had no room under the engine because of the hull.
If I was to use one again I think I would use it every other oil change and pull the drain plug the other times.

^ that has always been my concern as well Wayne.
With the S54 engine in my BMW I have learned that the drain plug is not the absolute low point. (not easy to tell because of covers)
Guys have pulled the plug after vac & found that there is only a drop or two on the plug itself.

On the S54, the oil drain plug is not the lowest point in the pan. The sump cover directly below the main pump intake is lower. And when you remove that cover after draining via the plug, you'll get wet; the pump will then empty out. I think there's a caution in the Bentley about this too (when removing the pan). As near as I can tell, this is by design; it helps prevent the brief oil starvation after an oil change that would result if the pump's main inlet was drained of oil.
In that case it might be the way to go. The only other concern is to get a good pump, I know some of them for the boats were more work than they were worth.
I was always going to run a drain with a valve on it from the drain plug so I could use the vacuum pump on the marine engine, but I never did do it.

I have never used one or even considered it for the reasons Wayne mentioned. Also to me it's really only useful on something like the S54 with the filter up top. Most others cars need to have the filter changed from below anyhow.
I'd be interested how much oil is left over in the S54. Is there a concern in fully draining if by design it's meant not to...versus benefit of full drain?
Does your new lift allow easy access to the pan drain cover? BTW, I noticed my cover is missing when changing oil this fall.

good point

I wondered about that too. In that quote above it mentions "possible oil starvation after an oil change"

Yes it's no problem at all. The only issue is holding the pan up while trying to wrench the plug.
I was going to make a hangar for the oil drain pan.

No doubt...but who knows, maybe it's not the BEST way either..
Good to hear about the new lift.

My apologies Gord and Wayne. I guess I was thinking everyone who owned a G out west was named Wayne or maybe..........Dustin, yeah that's it.
Typically we don't bring cars in just for a 20 minute thing, since we usually have lots of long term projects on the hoists etc. But if you're looking to do an alignment or a general inspection even - OR if you're an existing customer that's had a lot of previous work, routine maintainence is no problem!
