Lots of vehicle manufacturers in asean region insists 6mo/10000km even with fully synthetic oil. Your post cannot be generalized. Certain cars have small engine oil sumps that inhibit extended oil change intervals.

Owners manuals differ by manufacturer and region.

How do we reconcile that with Honda's recommended OCI at 10k kms or 6 months using Genuine Honda Oil (GHO). GHO not being specific as to mineral, SS or FS. The SA will give an automatic quote using FS but will use Mineral if the client says so and will still send you off with a smile and reminder to see you till the next 10k kms or 6 months.

Happened in my case, and the mineral oil used was even SL rated while the manual says minimum SM. I did not know these technicalities before.

Don't you find it weird that the latest FS oil still need to be changed every 6 months?? Sorry to disagree but 6 months O/C interval on FS oil is plain BS talk to me.

The chart I posted is based on current oil technologies and reviews. A good example below. Note that this is a 2007 Honda Fit/Jazz and test done back in 2010 pa using non-synthetic oil.

O/C intervals of 8,851 km and 12,231 km (using on-board oil monitor) and can extend for additional 3,219 km) of service (used oil analysis), therefore up to 12,070 km and 15,450 km using Non-synthetic oil.

Our Fit Gets Taken for a Ride

Before the initial publication of this article in August 2010, we took a 2007 Honda Fit to Jiffy Lube for an oil change to see what might happen to the average car owner. The car had an oil life monitoring system, and the system had recommended the past two oil change intervals at 5,500 miles (8,851 km) and 7,600 miles (12,231 km) on non-synthetic oil. In both cases, an engine oil analysis revealed that the oil could have provided at least another 2,000 miles (3,219 km) of service.

Mazda Toyota Honda Mitsuhishi and Subaru say 6months and you insist 1yr. Even engine oil companies recommend following vehicle owners manual.

USA mileage is not the same as stop and go traffic in the Philippines.

10000km(USA) is not the same as 10000km(metro manila)

Lots of freeways in the US.

My car gets 2,500 km per year only. Why would I change my oil every 6 months when I am using FS oil? Please explain.

AFAIK sir your FS oil will turn into sludge kasi if prolonged use in your engine.

Just because you do 2500km a year. Are you suggesting others to follow your oci?

Whether you use the car or not, oil that's in your engine inevitably gets contaminated, and that contamination breaks down the oil, reducing its lubricating capabilities.

As has been said above, you cannot compare US miles with local miles - our traffic and climate conditions are much more severe than what they experience there.

Noone's stopping you from your once a year oil change, but I've talked to many mechanics who've said that they've seen much dirtier low-mileage engines than those that are daily driven, simply because owners think that they don't need to change their oil regularly because they rack up very few kilometers annually.

i'm about to have my 10K pms soon for the hilux. planning to switch to FS, if i have the oil change at 20K do i need to change the oil filter * 15K?
though it's not daily driven, mostly from cainta to san juan/qc and forth routes(short trips?)but it's the traffic somewhat i worried most.
idk if i can call it a low mileage car, 10K at around 1.5yrs?
