Nice day here in Surrey,time for my third oil change since I have owned my used 2005 pulse.Using an extractor pump purchased at princess auto,I push down on the plunger and oil starts gushing out through the top of the handle,big mess,and I make a bigger mess trying to figure out whats wrong.I went inside and googled to see if I can find the problem and see that this happened to someone else.They contacted someone (distributor?) and they where told that the seals can fail with synthetic oil??I didn't have the receipt but princess auto asks for your phone number when you make a purchase so it was on file,whew!The one I had was marked up to 7.8L,I think.I traded up to a 9.5L oval shaped one for an extra $20 hoping for better luck.To dark to try again by the time I got home but thankfully we are having some nice weather here on the wet coast so I will try again tomorrow
