I use one of these on my Escape.
That's an interesting idea though, I am too stupid to come with an idea like that. Nevertheless, I still don't get why do you need a construction like that when you can simply call for help and professional people will make everything in your place.
OK. I tried it today and it was a resounding success.
Purchased a 2 gallon heavy duty pressure sprayer from Walmart today for $13. After I vacuumed the oil and measured it, I determined that I need to fill 6 quarts. Filled up the reservoir and pressurized it properly. The sprayer came with a detachable spray head so there was no need to cut off the tip. Places the wand in the fill hole, pressed the trigger and locked it in place. The oil trickled in while I emptied the old oil into the containers. It was about 35 degrees and the oil was thick but all of it got injected into the engine.
After I was done I covered the too with a shower cap and stores it back in its box.
It was a clean and easy process.
Highly recommended for the lazy among us.
