Welcome to tsikot!

is the pickup your first vehicle?

1)Check the oil levels at least every week - note if it goes down. If it's black, don't worry, diesel in the country is so dirty that the oil's already black a day after changing it

2)Regarding oil changes, diesel vehicles rarely need to us synthetic oils (once again due to diesel quality here). Mineral oils are fine, as long as you have an oil change every 5000 kilometers. Use the viscosity recommended on the manual. Generally, oil filters are also replaced during an oil change.

3)You can also opt to clean/replace your air filter if it gets dirty

4)Note if the exhaust is chugging out too much black smoke. Injector recalibration or an outright injector replacement may be due.

I'm assuming it's not a CRDi DMAX..

Then there's the usuals

-check the brakes, note the brake pad thickness
-brake fluid levels
-clutch fluid levels
-coolant levels
-power steering fluid levels
-check the belts if they'r cracked or frayed

Hmm. there's probably alot more, I'm sure someone more knowledgeable is bound to reply

thanks sir for the reply. it is also necessary to change the air filter when it reaches 5000 kms?

do you have a recommended brand or should I stick to OEM's?

I think oil filter should also be changed during engine oil changes.

Air filter? Usually every 20 thousand. Might be at shorter intervals if driving conditions are dusty, etc.

And yes, if engine oil change is done regularly at 5,000 km, just settle for mineral oil.

The oil filter's usually already filthy after 5k kilometers

With the air filter, as I said, you can clean it (pinapagpag kung drop-type) instead of replacing it every 5k km.

You can use any oil brand as long as the viscosity's the one recommended by the manufacturer. Personally, I use Castrol CRB.

Sir, regarding sa pag linis ng Air filter, I read in the manual na i should use a chemical for cleaning air filter by soaking on it. Any ideas kung saan ako makaka bili ng chemical na ito or any substitute? or i can just use Soap solution? TIA!
