Borrow a set from a friend and roll it up on both ramps and roll it off... The car does not have to
be horizontal, most drainplugs will drain all of the oil just fine on ramps or on an auto shops lift.
Whenever you embark on something you are learning for the first time, always have a mentor
to direct you the first time even the second.
Avoid, overtightening the drain bolt, burning yourself, removing the oil filter and leaving an old
gasket behind, overtightening the oil filter, not having the proper filter removal tool. etc.. etc..
Even a simple oil change can cause major damage if done wrong.
And never roll over those ramps too far, that can really mess up your fenders or other parts.
The proper steel ramps for your car are important too. Some are designed for lower sitting cars
And personally, I think those plastic ones are garbage.... This is just the tip of the iceberg....
There's even more things you may need to learn depending on what kind of car you have.
Been changing my own oil for over 28 years..... and have made stupid mistakes when I first
started doing them too....
