Sucking oil from dipstick tube

[CajunMick]

I have an oil sampler suction pump/cup, hand operated. Could slip tube into oil dipstick, pump oil out to get sample to send to lab.

i would like to get couple low mileage samples before a say, a possible 3,000 miles oil change, since new. The oil may be ok, but a “dirty“ filter only change might help prolonged oil life. That is if, only if, oil is ok.

Has anyone tried to suck sample(s) thru the dip stick tube?

I may have to deal with a dealer to recognize my scheme, assume filter holds all ”new“ particulates, yet oil is ok, and only filters need change first since new. Of course the ugly aspect Is removing the skid pane covering the oil filter.

Some might say if gonna change anything, do both oil and filter, call it a day. But any sample might say oil is good, with little bit metals. If that’s the case, maybe not change the oil?

IMHO, any half decent oil filter will hold a LOT more debris than the original wear metal. Then again, it may be "old school" but changing both before the manufacturer's mileage suggestion has long been sage advice for engine longevity. Many, including yours truly, dump the oil at 500 miles on a new or rebuilt engine. Just my 2 cents, and a nickle in change won't offend me. ;-)

Personally, I think you're wasting your time sending off an oil sample on a new vehicle. I'll save you the trouble and say: Some of your metal levels are higher than normal, but this is expected on a new engine. Send in a sample after you've hit 10-15K miles, if you really want to see how the oil is doing. I agree with others about doing an early oil/filter change on a new engine too. I did my first at 2K, but I have a hybrid and actual engine mileage was probably closer to 1500.

Agree. But oil not cheap like in my days in the 60s.

You correct. My intents are to have an early baseline of “metals” while rings still seating, bearings still tight, cam spinning on hard springs/valves, on factory oil, whatever that is. In Mexico it could be Pemex stuff?
