I posted this before but I did find a few more places that do oil testing in the Philippines. I would be nice to see what local vehicles are actually doing under the hood. Besides a test is a lot cheaper than running your oil for short intevals not based off of the actual facts of how your oil and filter are performing. This testing will also let you know how that aftermarket air filter is doing as well. And with oil prices as high as you are if you find you can double your oil change intervals it's worth every peso for the testing.
