After you drain it just put the cheapest oil then paandarin mo lang nang 2 to 3 mins. then drain it again u will see na medyo dumumi yung kalalagay mo lang na cheapest oil.

Then put na yung ano mang gusto mong oil, kung synthetic or semi synthetic.

my 2 cent lang...
This is a good route to take, i know several peeps who do this as well. You can also try the Caltex Power FLushing Oil in lieu of the cheap oil. You also dont need to top up on the flushing oil when this is done (i.e. a car with 4L capacity of oil will only need around 2-3L if its being flushed).

I do this with our rides every 30,000km or so.
