Oil change newbie question

[Nico911]

Hi everyone.

I'm just questioning myself : there's 2 draining plugs on a 911 (1985 in my case) but only one filling spot. It makes me wonder if there's a special procedure to fill the thing up back again ?

Be ready for a whole lot of oil to come out! It comes out fast and can overflow easily.

Enzo's link should have everything you need, good luck.

You can make a cheap 12 quart capacity oil drain pan out of a laundry detergent tub. Cut the tub with hacksaw or tin snips at a height that just allows you to push the tub under the oil tank - that is usually enough. A small notch to pass the drain bolt may be required - just make that sucker as tall as you can. A second, smaller drain pan is used directly under the engine sump.

EDIT: This is what I had the wife purchase for Father's Day: http://www.amazon.com/Fox-Run-12-Quart-Stainless-Mixing/dp/B0000VLQ0C/ref=sr_1_1?ie=UTF8&qid=1380555104&sr=8-1&keywords=12+quart+bowl+stainless.

This is a true understatement.... fast doesn't even begin to describe it!

You WILL have 10 qts of oil all over the place before you realize it.

I bought this for oil change use and it worked great.

Blitz/5 gal. oil drain pan (11845) | Oil Drain Pan | AutoZone.com

No need to lift the car, plenty of capacity, no splashing, and easy pouring into a container for transport.

DO NOT TAKE A CHANCE ON MESSIN UP YOU GARAGE FLOOR!!!!!!!!!!!!!

Get the LARGEST CAPACITY (12 quart minimum) container you can that is low enough to fit under both drain plugs. When unscrewing the plug on the oil tank, as it get close to unthreading (your using your hand now), push up as you turn to hold off the huge discharge. THE GAME IS: can you hang onto the drain plug without it falling into the oil pan and getting oil up to your elbow??????

Drain all the oil before changing out the filter.

Do not forget the new crush washers for both plugs.

After your first oil change, your a pro.

If you drop the plug......it automatically gets stuck in the oil catch can hole.....so, where an insulated glove as the oil will be warm/hot.

This may be obvious to anyone who has actually drained oil but...

You don't need a 12qt oil pan because you drain the oil in two phases. I happened to have two great smaller pans and use them one at a time. From my limited experience, approximately the same qty oil comes out of the sump and tank.

You better check your oil real fast if you get the same amount of oil from the tank and sump. Something is drastically wrong. Minimum from tank about 10 qts sump about a qt or so.

I gotta chime in with r-mm. I use 2 drain pans, and the tank drains more, but the ratio seems to be about 4 qts sump, 6-7 qts tank.
And yes, comes out very fast. I always try to get my hand/arm out of the way of the flow as fast as possible so as not to have oil running all the way up my arm to my armpit.

Yep what Craig said. Prolly not 1:1 but its not 10:1. Bottom line, the autozone special "blitz" that doesn't even say how many qts it holds has never done me wrong.

just fish the drain plugs out with a magnetic pick-up tool

[schulr]

Changing my oil today and got distracted and forgot to replace the filter. It appears I can still remove the filter without impacting the new oil I just put in. Is this the case?

[Targa Time]

Yes.

[schulr]

Thanks, pretty lame on my part.

[JQ911]

Not to hijack but I attempted my first oil change a while ago. I was half way successful having drained the oil at the right side oil tank without a problem. When I was about to remove the 15mm drain plug at the crankcase, I could not get it to move nor budge until the plugs got rounded off .

I got a vice grip and attempted to turn it as well as a little help with the hammer but the vice grip slides and further rounds off the drain plug. And so I ordered now from the host but my concern now is how to take out the rounded plugs given vice grip option was not successful?

I will try again tomorrow but need your expertise on these things.

^^ Pipe wrench and perhaps some propane/MAPP gas to heat case around plug.

[JQ911]

Thanks Jeff! Will try the above. I saw this and just curious if somebody has experience on these bolt removers?

[r-mm]

There is a lot of access around that bolt - enough to cut a small slot in it with a dremel or cut off tool and whack at it with a chisel and deadblow hammer. The torque value on that guy is up there, but once you break it free it'll spin off like a dream.
