I crank up both engines and generators and let them run for about 45 minutes. I put a load on the generators and put the engines in gear with the trolling valves active. After I shut everything down I pull my oil samples. Then I proceed to pump the oil out and start changing filters.
To answer the question, very warm. The pump won't pump cold oil.
My vehicles I take to the oil change place.

I change it warm. It needs to be warm, but not hot.

They can change it at any temp they want. I don't care.

My last change and rotate was 16 bucks (dealership). I am not going to crawl around under the car for that, no way in hell.

Guess I'm the only one. I do it cold. Temps down here don't effect oil flow that much. Get up in the morning after truck has sat all night and I know that all the oil that's going to be in the pan is in the pan. Remove the drain plug, drain the front fuel/water separator, remove oil filter that is half full now (helps Ram 6.7 less mess), replace front fuel filter, replace rear fuel filter. By this time there's little to no oil dripping from oil drain hole. Button everything up. I'm crazy so I don't even pre fill my oil filter. I poor 3 gallons of oil in the oil fill and fire her up.

Most synthetic base stock is made from natural gas. This results in an optimal, uniform molecule size without all the impurities, such as paraffin. This gives synthetics superior viscosity characteristics, particularly when soot loaded and when cold.

Bingo! I usually do mine after a trip into town. I take the long way home and it's up in the air plug pulled and I do something else for half an hour or so to let returning oil find it's way out.

Cold, after the vehicle has been sitting on ramps overnight. Takes longer to drain, yes, but I do other things to the vehicle and by the time I’m done it’s finished draining.

I do hot. With that being said, with the engine cold I first loosen up the oil drain screw (maybe a 1/4 turn to make sure it will break free easily) and then back to tight. Then, I do the same with the oil filter (break it free and then back to tight).

By doing this I do not get any exhaust pipe burns on my arms or hands from trying to get in weird postings trying to apply torque to the plug or filter.

Don't ask how I know.

Warm for me. I figure just about warm enough after I get the other car out of the garage and the ramps set up.

I learned to change oil from my master mechanic uncle. He taught me to change it hot(warm) for the cleanest change, including for all the reasons stated above. I don't change my oil anymore, but I don't think this principle has changed.

I drive it, get it home put up in the air and drain it right away. The "stuff" in the oil is suspended. The oil is hot so it drains quicker. I also have the car angled abit so that the drain plug hole is tilted towards the drain pan. And I also let it drain for at least 10-15 minutes before I put the plug back in.

Back when I used to change oil, I'd let it drain overnight. Every now and again I'd then after draining I'd add some really cheap high detergent oil and run it for 15 minutes or so and then drain that overnight. Probably overkill but it made me think I was really cleaning that sucker out.

I put one of those on last year and I love it.


I learned about those here on SIGForum and have them on my F350 and Honda Odyssey. I used it today when I changed the oil on the Odyssey. Attach a hose to the valve, put the other end into an empty oil jug from the last oil change. No mess, no burned hands. I punch a hole in the filter and let it drain.

Thank you again, to whomever suggested these.

Hot.

It also depends on how long the vehicle has sat. I bought a car that sat for 10 years and drained a gallon plus of water before oil started to flow. Condensation, humidity factor.

Love some of the answers. Growing up our Gas Station had most of the FHP work. Those cars would come in freaking smoking hot, right on to the lift and I would have to change the oil. YIKES! Noting like pulling off an oil filter right next to the exhaust pipes of a car that had been running hard for the last 6 hours or pulling the plug and feeling that nice hot oil on your hands!

I would say, close to hot, but let it sit for a good 20 mins before you drain it.
