This isn't true is it?
Unless it takes you just 10 minutes to:
a) Locate the tools you need -
One spanner, its on the wall with the rest of them
b) Jack up the car and place on axle stands -
Not needed.
c) Remove the drain plug
d) Wait whilst oil drains
e) Remove and replace filter -
Doing this while waiting for oil to drain.
f) Replace drain plug and new sump plug washer
g) Remove axle stands and lower car -
Not needed
h) Refill with oil, checking level as you go -
Not needed 99% of the time i get it bang on first go so only one check.
i) Put all tools away
If that takes you 'no more than' 10 minutes then congratulations, you are an internet mechanic hero
