(I think I saw some of the info I'm seeking about an year ago, but can't locate that thread): Hi guys, I'm planning to do an UOA (my 2nd one on the T-bird)in a few months, and have some questions: 1) I want to take the oil sample myself this time. I'm planning on using the oil-sample-pump seen on the Blackstone website. are there similar, but cheaper sample pumps? where to find them? 2) I know I have to get the oil hot before taking the sample, BUT: When I insert the tube of the sample pump into the dipstick tube, how do I prevent the oil from the very bottom of the pan being drawn to the bottle? I want to get some oil from the "middle" of the reservoir... is this thinking correct? shall I lift the tube after I feel that it touches the bottom of the pan before pumping? What's the best "technique" to get some clean oil from the middle? Anything else I should be careful about? 3) Can i use this oil pump to draw out about a quart of oil to be replaced with another oil if I need to? or does it work only for very small amounts? 4) As of now, which lab would you guys recommend? BKstone or ButlerCat? Thanks a lot for any tips/advice you guys have on this.
