When to change oil

[kisshmet]

3 sasakyan gamit ko: Mitsubishi Montero Sports GLX M/T 2010 , Honda City Lxi 1999, Toyota Hilux 2.4 1994......every 5000 kms. ako magpalit ng langis at oil filter kada sasakyan. ok lang ba to?????? kaso, umaabot ng 6mos. to almost 1 year bago ako maka 5000 kms bawat sasakyan.... retired ba kasi ako...... maganda pa kondisyon ng langis na pinagpalitan ko.....di pa gaanong maitim at di lumalapot langis.....ok pa naman andar ng mga sasakyan.....wala pang ino-overhaul at di mausok......puro malakas pang humila.....maski yung 1994 Hilux ko...... Ano po masasabi/maipapayo niyo?????? Salamat!!!!!!

follow manufacturer recommendation if your vehicles are still under warranty, otherwise follow your instinct old-timer

you can also do a mathematical approach by keeping tabs on the amount of fuel your car needs to burn in order to cover a specific distance. as time pass by your engine oil deteriorates as it accumulates soot & that technically result in a surge in fuel consumption. so youre now faced with the dilemma of whether its more cost efficient to replace your dirty oil & save on gas consumption or keep the sullied oil & spend more on fuel. i believe this is the strategy employed by big transport company with a fleet of vehicles to maintain to save money

just bear in mind when you opt to change oil you hit 2 birds with one stone. you protect the engine from the adverse effect of wear & tear at the same time you save on gas
