I'd go for the semi-synthetic oil.

Great for everyday use.

Not too disposable as mineral, not to expensive as fully-synthetic.

FYI po. before switching to fully synthetic oil (from mineral based oil) make sure na OK pa ang condition ng mga oil seals and gaskets ng engine ng car, otherwise, expect oil leaks here and there. so kung medyo old na ang engine, have those seals and gaskets replaced before pouring in the fully synth oil...

semi-synthetic oil lang gamit ko pero change-oil every 5K. this way regular ko nache-check ang underside ng auto and others.....

happy motoring

Synthetic is engineered to perform better. Consistent ang kapal kahit high temperatures, doesnt degrade as fast as mineral oils, better detergency. Mas mahal nga lang, altho kung kaunti lang budget, semi synthetic is a compromise.

fully synthetic gamit ko, lampas na 6 months ang ganda pa ng itsura ng oil, pwede ba filter lang muna palitan ko?

kasi ganda pa ng oil, ang linaw at dipa malapot, nag- add lang ako once in a while

never tried semi or fully synthetic before. pero reading the posts on this thread, mukhang okay ang value ng synthetic. masubukan nga!

Get whatever you want.

In everyday driving, many of the advantages of a fully synthetic oil are wasted. If you thrash your engine, then go ahead and bite the bullet, but everyone else will be just as happy with mineral or semi-synth oil.

It's not the makeup of the oil that matters, it's the ratings, such as viscosity and oil grade.

Regular lang gamit ko, but I might try fully synthetic oil sometime in the future.

Synthetic is superior to mineral oil in terms of stability at sustained high temperatures. It does not breakdown as quickly. What is critical is to choose the right viscosity for your engine. Ideally you should choose the lowest viscosity that will enable your oil pump to still reach the maximum psi (~65 - 75psi). As a rule of thumb, if you change oil frequently eg. every 3000kms, it would be more economical to use a mineral oil. But if you go with extended drains eg. every 10,000kms, you would be better off using synthetic. Another rating you need to look at aside from viscosity is the API (i.e. SJ, SL, CD, CG) or ACEA (A3, A4, B3, B4) ratings. You should get at minimum the recommended rating by your engine manufacturer.

I use 30 grade oil, fully synthetic for my cars with a minimum rating of either A4 or B4.

fully synthetic gamit ko kasi turbo charged ang engine ko

mataas ang temperature na na endure ng engine kaya dapat synthetic

para di mag breakdown agad yung oil

Synthetic is too expensive. I usuali use multi-grade oils with high api ratings. At most seme-synthetic basta di lalagpas P250 per quart. Basta normal driving lang with occational hataw. just be sure to change oil and orig filters every 5000km. Its is also important to make sure that your cooling system is ok. Kahit sysnthetic pa yan, pag nag overheat makina lusaw ang langis

if you frequently rev your engine higher than 3K RPM and mahilig sa spirited driving I would suggest mag synthetic oil ang gamitin.

SOme people would not recommend synth oils on old cars and old engines because of its viscosity. Mas malabnaw ang synth oils kesa regular/mineral oil kaya ang tendency nito ay nagli leak. of course luma ang car luma na rin engine at oil seals nito kaya tumatagas. but yun good side naman nito eh mas mataas ang boiling point nito thus mas resistant ito pag madalas mainit makina. mas maganda ang lubrication. hindi agad masusunog ang oil.

just try to put it this way, if you have a car that travels everyday and runs for more than 15 hours, whether it be straight driving or w/ pit stops, use mineral oil. its cheaper and just as effective, IF u change your oil every month or every 45 days. this is the common practice of taxi drivers. if you have a car that doesnt run like a taxi, use fully synthetic and you can choose to change your oil whether it be every 5 thou kms or every 3 months or which ever comes first. this way you dont need to measure if you had a month of heavy driving or if your car was just stuck in the garage. we've had several cars and even a taxi, works like a charm but then again you really cant blame the method if it doesnt work for you bec you also need to consider the age of the car. we have a new honda civic now and according to the manufacturers notes, the car can only use fully synthetic oil but the oil change could be every 10 thou kms or every 6 months or again w/c ever comes first. by the way all of our cars were casa maintained and we never experienced engine problem or performance issues. ;)

boss kaya po malabnaw ang synthetic kasi malamig pa ito. ganun talaga ang characteristic nito. habang umiinit ang makina lumalapot ito kaya mas maganda ito sa mga older engines. engine wear usually occurs during start up dahil wala pang langis sa mga singitsingit. yun ang trabaho ng synthetic agad sya susuot sa mga parts ng makina to avoid wear. at habang tumataas ang temperature kumakapal ang texture nito. i use castrol gtx 10w 50l

Fully synthetic oil na, even if its' a bit expensive. But better use it on new engines. The expense will be offset by the savings of a properly maintained engine, in terms of less trouble, better fuel efficiency.
