Is doing an oil change using an suction tube through the dipstick as effective as the drain bolt?

I saw a nice device in a magazine. A pump that drains the oil through the dipstick. 2 questions came to mind. Does it miss a lot of the oil because it doesn't get to drip? And what about the oil filter? Does that need to be changed everytime?Is doing an oil change using an suction tube through the dipstick as effective as the drain bolt?
It could miss quite a bit of oil - you can't really see if you've gotten it all out. The oil filter definitely needs to be changed every time. Why would you want to change the oil like that anyway? I don't see the benefit.Is doing an oil change using an suction tube through the dipstick as effective as the drain bolt?
I have one of those vacuum devices for draining oil through the dipstick. I bought it for my boat, but tried using it on my truck. It did not work well due to the shape of the oil pan in relation to the location of the dipstick. When I put the vacuum tube down the dipstick tube, it does not go into the deep part of the oil pan, and misses probably 4 of 5 quarts of oil. As for the oil filter, yes you have to change them every oil change.
the most affective way to change the oil is to drain it from the oil plug and those suction deals don't work to good, and yes you need to change the filter every time you change the oil,it does all the work of cleaning the oil ,good luck.
Either way you must change the filter, it always holds oil. The dipstick system is effective enough, that's how you change the oil in boats, but be warned it is very slow.
it may miss some oil, the filter still needs to be cahnged and b/c your motor is NOT designed for that, it could damage the engine.
Quit being lazy and do it the right way. Drain the oil ( from the drain plug) after warmed up,and change the filter every time. The pump wont remove all the oil............md
I probably wouldn't trust it, and yes the filter needs changed too.
