Time to Change Oil
Hope this blog helps all the clueless people who goes to either the casa or the “talyer” to have thier cars tuned up or the scheduled “changed oil”. Why do we need to change oil? What is the right oil to use? When the mechanic says, “Sir, what do you prefer, fully synthetic or semi-synthetic?” I hope through this blog you won’t be giving the mechanic a puzzling face and say,” ah cooking oil pwede?”
SO WHAT DOES THE OIL ACTUALLY DO?
According to the “Car Bible”,
The point of engine oil is primarily to stop all the metal surfaces in your engine from grinding together and tearing themselves apart from friction whilst transferring heat away from the combustion cycle. Engine oil must also be able to hold all the nasty by-products of combustion, such as silica (silicon oxide) and acids in suspension. It cleans the engine of these chemicals and build-ups, and keeps the moving parts coated in oil. Finally, engine oil minimises the exposure to oxygen and thus oxidation at higher temperatures. It does all of these things under tremendous heat and pressure.
A quick guide to the different grades of oil.
|Fuel economy savings
Enhances engine performance and power
Ensures engine is protected from wear and deposit build-up
Ensures good cold starting and quick circulation in freezing temperatures
Gets to moving parts of the engine quickly
Good protection within the first 10 minutes after starting out
Roughly three times better at reducing engine wear
Increased oil change intervals – don’t need to change it quite so often
|Basic protection for a variety of engines
Oil needs to be changed more often
For the past 6 years I have been using the semi-synthetic oil for my cars. I would always ask the mechanic if it is okay to use semi-synthetic than the fiully synthetic which is almost 50% more expensive. Almost all of them gives the standard answer, ” Yes it’s almost the same” ( which I really don’t know what it means thus this blog)
For my last tune up, I had my car tuned up and oil change at RAPIDE and was once again asked what oil I want to use. So for the first time in 6 years, I tried the fully synthetic oil. I did feel a slight difference on the performance of my car ( a Toyota Fortuner) because of the change in the oil used. So maybe it does make a difference.
Being a nobody in cars unlike some of my friends who are expert in cars, here is my humble opinion on motor oils.
If you have a bigger car ( Starex, Fortuner, Innova and the likes) and you have the budget to purchase a fully synthetic oil by all means do so. But if budget is too tight for the month a semi-synthetic oil will do.
For smaller cars, semi-synthetic oil will do especially cars for city driving.
As what my mechanic said, “slight difference lang naman yan sir” which I am still trying to figure out the meaning of.
To all the car enthusiasts out there, hope you can reply to this blog on your insights about oil change. What is better Fully Synthetic or Semi- synthetic? What do you recommend? Is there really a slight difference? And what does slight difference mean?
