And why do you think that theres crude in tha pan that flows out if you remove the plug?Personally I try to discourage people from using the what I call " only get maybe 4 qtrs. out of 5 and leave the crude in the bottom of the oil pan" tools unused. They make great brake fluid revivor or drainers however..

- key thing here as with all oilchanges is that you shouldnt wait to long Before an oilchange...
- next importand note is to change the oil on a warm Engine, it´ll take forever to get Cold thick oil out with a vacum changer. so its kind of self instructing.
Theres isnt a quart left in the pan and you can easily pour in half a quart or so to flush the bottom out.
- whats most important is that you do change your oil on a regular basis.
I like no more than 10 kmiles or atleast once a year, if its only short trippning twice a year. Always change the filter.
And i use HDEO if the Engine doesent have a finickly MDS or VVT system, they are cheaper and better performers in most ways except for viscosity availibilty. Chose an CI or CJ one
