Do not be ashamed Mol...I have done hundreds of oil changes and it is a messy horrible job....
careful of hot oil!!
make sure you remove the old rubber/neoprene gasket from the block...that is...make sure it comes away with the used spin on filter.
make sure the groove is clean where the seal came from (yes, on your back with a light looking up)
do not overtighten the filter....you just need to compress the gasket slightly...check for leaks/tighteness each day after you have done it if you are not sure...the trick is getting it tight enough to seal, but without squashing the gasket to oblivion and tihght enough so that it does not unspin and dump your oil
its a good idea to 3/4 fill the new filter with clean oil before fitting....and to make sure the new gasket is wet with smeared clean oil before fitting.
Do not overfill the engine....if you do...and this you find after running it several times...crack the sump plug and let some out (do not overtighen the sump plug....that ping!! noise means trouble!)
Good luck...don't swear too much
