Couple things to note in my experience with my merc E550..m278 engine, bi turbo 4.7l v8. I specify because I'm not sure all mercs are like this.
1. The filter was top side so oil changes were extremely easy.
2. The oil dipstick tube was a large diameter, maybe 1/2 to 5/8 inch.
3. When inserting the small tube through the dipstock tube to the bottom of the engine I had a a hard time extracting much oil.
4. I found that on this particular engine, you did not have to get the suction tube down the dipstick tube. Just use the large tube stuck into the top like a cork...the suction will draw 100% of the oil up the dipstick tube. (Open your filler cap)
5. Because the m278 is a dry sump engine you must do it this way. It takes 8.8 quarts (if remember correctly) and it would get every bit out.
So in short, on your gl .....if the suction tube down to the pan does not work, try using the actual dipstick tube as the suction....pm me if you have questions.
