Ano po masasabi/maipapayo niyo?????? Salamat!!!!!!

the recommended change oil interval is 3 months or 5000 kms whatever goes first, but I've read that somehow, this rule may not hold true. but then, oil changes are cheaper than to have a damaged engine.

ako, i get my 5000 kms in around 4 months... dun na lang ako nagpapalit.

ano ba langis ginamit mo mineral or fully synthetic oil???????

[kajjo1]

Retz, Top 1 synthetic oil (diesel) sa Montero.....Shell R3 sa Toyota Hilux at Shell Helix J sa Honda City

Sir ung Top1 hindi un talaga FS oil. Kaya every 5K-7K change oil. The rest every 3K-5K OCI.

I usually go with what the user manual states. It also provides additional guidelines if the car is driven hard, or driven in a lot of traffic, or pulling heavy loads. Usually more often. One of mine says every 5k mi. or 6 mos. for mineral oil, 10k mi. or 12 mos. for synthetic, the other is 5k mi or 12 mos. mineral only, 15w40.

Change oil only when they are dirty and sticky, there is no hard rule in changing oil. Remember that oil only prevent the friction of engine metals and so they gather dust and some engine residue that is why you change them. I myself have been using cars of different brands for almost 20 years and sometimes I change oil a year or a year and a half only when it is dirty & sticky. Your engine has a filter to keep it clean and the dirt that accumulates that cannot be filtered are the ones that mix with the oil. Changing oil every 5000 km was the marketing strategy of oil companies to keep them selling and they just heat or scrub the oil to purify it and then sell it to us again.....

Thanks, Retz

follow manufacturer recommendation if your vehicles are still under warranty, otherwise follow your instinct old-timer

you can also do a mathematical approach by keeping tabs on the amount of fuel your car needs to burn in order to cover a specific distance. as time pass by your engine oil deteriorates as it accumulates soot & that technically result in a surge in fuel consumption. so youre now faced with the dilemma of whether its more cost efficient to replace your dirty oil & save on gas consumption or keep the sullied oil & spend more on fuel. i believe this is the strategy employed by big transport company with a fleet of vehicles to maintain to save money

just bear in mind when you opt to change oil you hit 2 birds with one stone. you protect the engine from the adverse effect of wear & tear at the same time you save on gas

right ob the nose, kisshmet!!!!! thanks.....

5,000 km is reasonable. As to the 3-4 months interval, this depends on a lot of factors -daily driven in heavy traffic, pulling and carrying heavy loads, etc.

However, there is a cheaper way to unequivocally determine when change is imminent---look at the physically condition of the engine oil. How many of us regularly open our hood to find out?

[Retz]

Sir, i regularly check the condition of the oil (once a week) via the dipstick.

With due respect, buhayin ko lang ang thread na ito...

I use Top 1 HP, synthetic blend motor oil 20w50 for my 2nd Gen 4AFE, over 5 months na siya pero a little over 4k kms pa lang mileage. Nag-experiment ako sa mga low priced oil filters starting with Toyota OEM C110 which I used for 4 months, then, AGL auto filter cross ng OEM for a week, next is ViC C110 for two weeks and at present, slightly bigger diameter and longer Bosch OT 043 (cross ng OEM Toyota C113). Sa ngayon, maganda ang viscosity at light brown na ang color ng oil, smooth ang feel between fingers until now. Does this means, pwede pa use until 5k kms or paabutin ko 6 months?

Most car enthusiast will tell you that "your eng oil is as good as your oil filter". This is very true. So invest in a good quality oil filter & buy a reputable eng oil brand acc to your budget with a viscosity that is recommended in your owner's manual. I'm more comfortable with oils that turn dark after a few thousand km mileage than the ones that remain transparently clear. The reason is very obvious...

There are 3 types of car guys.

1. The guy that forgets to change his oil.
2. The guy that you don't need to remind when to change his oil.
3. The guy that does not know when to change his oil.

This could also be said about WAXING a car.

Nasa user manual when to change oil. Safe approximation ang nasa manual based on OEM filters and lube.

Kung maganda ang oil and filter, pwede mo extend.

Pinaka accurate ang oil analysis thats why some fleet and industrial machinery operators do this, extended oil life tanslates to more savings.

Kelan kaya magkaroon ng oil-test strip na pwede mabili sa auto shop para hindi na pupunta sa oil lab for analysis?

[Retz]

Just follow sir number001 guide on when to change oil. I think that is more than safe enough.

It's advisable to drive it around the block to circulate other fluids and oils.
