Poll: Draining Engine Oil; Warm or Cold?

[oj88]

Conventional wisdom teaches us that in order for oil to flow better, you'll need to warm up the engine for 5-10 minutes, turn it off, and then wait another 5-10 minutes before draining it.

I want to try changing the engine oil after the vehicle has been parked for several hours or overnight. Theoretically, this means that most of the oil has had a chance to collect in the oil pan. In other words, I should be able to remove as much of the old oil this way.

Consider that we live in a tropical, oftentimes, hot climate.

So, where do you stand in this?

If you are in abit of a hurry, draining the oil after 5 mins warm-up for about 30 mins would be enough.

But overnight draining would still be the best imho or at least an hour or two. I think almost all of the oil would drain already after a couple of hours. Tagal na nun.

Kung mainit makina sa loob ng isang oras or less ay nakababa na lahat ng oil except sa areas na may lubog..

a 30 minute drive from the house to the gas station, where i have my oil change.
because of this, my oil changes are always on a still-hot engine, with maybe a 5 minute interval from engine off.
i don't oil change at the house anymore. hassle the getting rid of the used oil.

We also used to DIY it at home back when my dad was still alive and we only had 1 car.

The night before, my dad would even jack up the car on one side so a lot of the oil would go to the side where the drain plug was.

We always thought that was clever because it would ensure that the majority of the old oil would drain out.

Doesn't matter ang vote ko.

Though when I DIY'ed my oil changes, the car has been parked for hours or overnight. I try to make sure I've driven it hard or long previously though, so the oil "thoroughly circulated" and carried most of the gunk into the old filter and/or drained into the oil pan.

Ang init ng langis minsan pag hot pa ang ang engine. It's easy to get splashed sometimes when you're just DIYing it in the garage. Sawdust wasn't always available din for any spills.

when oil has been sheared and all, it will flow really well. I do my oil changes and vehicle is now at 361,999km. I have thick gloves and gloves over that to protect from the chemicals.

DIY, after ko gamitin pero pahinga muna for an hour or 2. Then tutulugan ko or after 2 hours to refill. Ayos!

Warm engine.

I usually drive around 15-30 minutes first. Park on an even surface, shut off engine and wait for about 10 minutes before draining the old oil.

Compared to draining the oil when the engine is totally cold, parang ang hina ng labas.

Noticed this hundreds of times nun nag work ako as lubeman dito sa pinas at sa Saudi.

Lalo na pag diesel engine at SAE 40 ang gamit at overnight naka park. Grabe, after masalinan ng bagong langis parang hinde na change oil.

Na try ko na rin mag drain ng oil overnight. Hinde ko na inulit. Napansin ko nagkaroon ng alikabok sa may labi ng thread ng drain ng oil pan. Kaya napaisip ako.

At the end, regular oil and filter change, plus quality oil.

I thought gasoline stations are willing to get your used oil for free.

Instead of overnight drain.. much better to do oil flushing using the cheapest monograde oil.. like petron mo40 nasa 135 pesos per liter.. use 3 liters to flush..

what are you flushing?

[playplugg]

Kung meron lang po akong Proper tools/equipment + the updated Maintenance Manual ng Certain Brand ng sasakyan..

Ang dali sundin ng DIY..

kung home based at limited ang gamit,

Kung sobrang Warm ng Oil, paso ang mangyayari.. , kung malamig naman ang engine, hindi naman lahat ng mantika, drain sa oil drain...

"Normal Temp" saka start lang ang sasakyan ng 30 secs. to 2mins, para lang mag-circulate yung oil..

Saka yung "Flushing Fluid" na sinasabi... chemical yan..

Engine Oil pa rin ang pinaka-effective na "Flushing-Fluid"

Crank ang datingan dyan... paandarin ang starter ng few seconds.. habang flushing..

para walang residue habang flushing..

Dapat ang Oil na Gamit... kung FS.. yun ang gagamitin, kung Mineral Oil, yun lang din..

Hindi dapat pag-haluin ang FS at Mineral Based.. magkakaroon ng chemical reaction saka sisirain yung mga rubber gasket(s) nyan pag dating sa makina..

You can use cotton gloves and cover it with nitrile gloves.

Cotton gloves para iwas init. Nitrile para incase na matapunan ng oil is hinde makakatagos sa gloves. Sa umpisa hinde maiwasan na masalo ng kamay ang pag drop ng oil, pero matutunan din po paano iwasan afterwards. Darating ang time na no need na mag gloves and kahit isang patak is walang dadapo sa kamay.

Marami klase ng pang “flushing”. Pero para sa akin, unless contaminated ang engine oil, like nahaluan ng tubig, saka lang ako gagamit pero with the same engine oil.

[Lew_Alcindor]

Depende kung ano temp niya sa time na available ako mag oil change.

I usually drain overnight to it doesnt matter.

Iwas din ako sa sobrang init ng makina dahil susceptiple to stripping the thread of the oil plug.

[ice15]

Answered "cold" kasi that's how I did it during my DIY days (college)

Pero hot when I started working kasi wala na akong time, so service center ko na sya pinapagawa

[ninjababez]

voted doesnt matter ^_^
i do it usually after 30 minutes (or more) naka park, mainit naman lagi so mag drain talaga ang oil.
tapos pag patak patak nalang; i jackup passenger side, then driver side. yosi break, youtube, or kain muna bago punasan bago kabit drain bolt; next naman yung oil filter hehehe

When engine is cold, oil is thicker, thus, draining it when warm would be better as the motor oil is less viscous

Di ba mas malapot pag mainit? San napunta yung 0w30?
