Will all oil drain out if I remove oil filter?

Okay, let me get right on that. Might take another 5-10 years though.

Anyone can throw up something on the internet.

If I read that link correctly, they tested those oils on an engine, and at X,XXX amount of miles, they take a small sample to evaluate the condition of the oil. What more can you ask for?

I actualy take a taste of it with my tongue. If it tastes sandy and resembles eating a clam, I change it. If its smooth and silky like pudding I keep it. Everyones got their own little ways of testing their oil ya know.

I started using Amzoil back in the mid 80's, they were the first one to bring synthetics to the market. I change the filter at 10-12kk miles and the oil at about 20-25k. Amzoil and other premium synthetics have been 25,000 mile oils for many years. Amzoil does recomend using a bypass oil filter in addition to a good quality oil filter. If ANYONE has doubts that a premium synthetic outperforms standard oils, even after 25,000 miles, I suggest they prove their paranoia by having the oil tested. Oil testing kits are widely available and they are the ONLY way to tell if the oil really needs to be changed.
I do know of a test on a semi truck engine where they did not change the oil for about 350,000 miles. They tested an oil sample every 25k and replaced the filters. At 350k the oil still was in-spec but they decided to see for themselves and pulled the engine. The overhaul revealed practically no wear, every part including the main and rod bearings were in within spec. If a massive diesel that pulls heavy loads and has to deal with the intense effects of the diesel environments can run a good synthetic for 350k, I think our cars will be fine at 25k.
Now in case that isn't enough, I will add my own testimony from my former career as a mechanic:
When I was in high school, many moons ago, I worked in a small service station with a very knowledgable guy. He educated me about synthetics and I was sold even without direct proof. One day a long-time regular customer came by for an oil change. I had just started working at the shop and thought it was kind of odd that a customer would bring their own oil. The car was an early 80's civic and the owner was a lady in her 50's who worked as a travelling salesperson. I was also amazed that she only changed the oil every 25k, when everyone had taught me to change at 3k. I changed her oil at 50k and again at 75k before I moved on. I graduated high school, worked for a year then went to Wyoming Tech to get my degree in Automotive Technology. When I came home I took a job at another idependent shop and one day I noticed a familiar civic! Sure enough, it was the same lady, same car, roughly 2-3 years later. This time she came in for her 25k change with 175k miles on the car. The owner of the shop was not entirely sold on this "expensive" synthetic oil, that is until we did a compression check as part of a tune-up. I can't remember if the spec for that car was 120 or 150 psi, but I'll be damned if every cylinder wasn't within about 2-3 psi of spec!
He was sold, so am I, and I will never use cheap oil again. It was also fun to silence critics when I changed the tranny oil in my 5spd 98 se and saw a 1.5-2 average m.p.g increase.
And to answer the poor guys question, SURE! you can easily change the filter with maybe 1/4 quart of oil loss, I do it every 10-12k. I only takes about 5 minutes and it's really easy to do, no jacks stands required.

dont be so hard on Cheezwiz hes from Missouri. he probably voted for bush too.
even after showing him the "real-world proof" ppl created using a controled experiment and then the oil was analyzed by blackstone labs, who is a very reputable oil analyze company and he still says he dont believe it....
must be environment(missouri) or genetic that hes an idiot
