I would like to ask if I may, my new car is about 14000 km now after a year. Thus i rarely travel far and long.

I do drive alot in city with stop & go traffic and thus I will never reach 10,000km OCI by 6 months.

My question is must I follow that 6 months interval? Is there an expiry date for my engine oil? Let's say in 6 months I only driven 3000 km but daily and short trips.

Can I prolong it to 10,000 km then only change even though it'll take 1 year and more?

I'm using Petronas syntium 800 10w-30 semi synthetic btw. And the car is proton saga campro vvt.

Hi zeng,

Thanks for the reply. I would like to confirm again (after seeing my service invoice) that the engine oil I'm currently using is Syntium 800 SE 10W30 SN-4L.

According to OEM recommendations (source from my car's manual):

1. There are 3 sections where engine oil recommendations are mentioned:
(i) At the front page where it says "PROTON recommends PETRONAS Syntium or Mach 5 product ranges meeting API SL or higher"

(ii)



(iii) Specs sheet on recommended lubricants: SAE 10W-30 or equivalent "SERVICE SL" or high grade


2. There are 2 conditions for oil change as stated in the manual:

(i) Periodical Service Maintenance whereby oil change is set at 10,000 km or 6 months (whichever comes first)


(ii) Severe Usage Service Maintenance whereby oil change is every 5,000 km or 3 months (whichever comes first)
- Severe operating conditions include but not limited to the following cases:

1. Driving on dusty roads or in an area in which the vehicle is likely to be exposed to salty air.
2. Driving on tough roads, on submerged roads, or hilly areas
3. Engine idling for long periods of time or short distances traveled during cold weather
4. Frequent, sudden application of brakes
5. Use as a rental car or taxi
6. Operation under excessive load
7. More than 50% operation time in heavy city traffic in hot temperatures of 32 Celsius or higher
8. Overloading
9. Operation in extremely hot weather condition.


Now my daily driving is about 15~20 mins to work in the morning. Ranging from 10 km ~ 19 km (depending if I have to drop someone off elsewhere first).

And on the way back home it'll take about 30 ~ 40 mins with I guess similar range but more traffic lights.

I do face a lot of traffic lights but rarely stuck in jam or idling for long periods of time. I'm also using a manual transmission car if it matters.

-----------

Regarding warranty, I'm sort of opting after my 3rd change (due to last free service) or even before that to do my OCI outside and possibly using other brand/quality of engine oil. Any recommendations? I'm sort of looking into cheaper oils like those in Lazada "Car Doctor" brands where have high review ratings & cheap fully synthetic. But a little skeptical as it is sort of too good to be true.

The rm60+ service charge is pretty darn expensive but yea I'll be losing the warranty. I am a little concern about warranty but would like to know if there is a cost saving route as well. Will have to weigh the pros and cons later.




*edit: I would also like to mention that I'm not so familiar with the technical specs & knowledge on engine oils
