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.

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

that may be.
but i still have to bring it to them.

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..

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

Yeah, either way 1% difference in the drained oil won't make much of a difference naman dito sa atin because medyo warm climate natin. Unlike in winter countries where it is better to warm the engine oil before draining it.

I think the best would be if your engine temperature is warm when draining oil. DIY oil change is not an easy task as it requires enough tools and skills. You just need to know the proper procedure to avoid any mistakes. Draining your oil also requires proper disposal to avoid the mess in your area. However, it's still best to bring your car to your trusted car shop if you're still hesitant about the process to avoid any problems that would affect other parts of your vehicle and lessen its functionality. Hope this helps!

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.

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

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.

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
