- - - Need Winter Advice__Big Time - - - -
Hey gang,
I've been away from home for a while now. I left my baby without changing its oil. Its been sitting in the garage for about one month now. My question is - when I get back home to U.S, do I start it (warm it up) and then change its oil. Or do I simply change the "old" oil, without making the dirty oil run through the engine?
As usual, I always appreciate the forum, and you guys...

well....I usually run my car before draining the oil just so it flows faster....at this point I would imagine everything has pretty much drained down anyway....I suppose you could just drain it and add some new oil to help flush out any dirt that may have settled and then fill it as normal....
FWIW I doubt that starting it and running would do anything more than just circulate the oil
but I am no expert

I would say drain it, add some new oil, let it drain, make sure the new oil filter is filled with new oil before installing, then fill with new oil.
I do not see why you would want to run the old oil through the engine first.

That's exactly what I would do.

There are many reasons to change engine oil. Three that might apply are particulate matter, moisture, and acids that result from moisture.
If the oil is very dirty or oil mileage is high (7k+), then suggest draining it without starting it, remove filter, pour a new quart in engine to flush the pan, reinstall plug, pre-fill the new filter and install it and the new oil (approx 7 quarts between filter and new oil, excludes flush quart). Reason: don't want to pump dirt and acids around the engine.
If the oil is clean and mileage is reasonable ( less than 5k), then take it for a drive and get the oil up to temperature (200+) and thereafter change the oil. Reason: removal of moisture which condensed inside the engine block after last engine running is better removed than to remain for immediate contamination of the new oil.
P.S. if easy to do, don't forget to raise the butt a bit higher than the front (e.g. 1 notch higher on jack stands or don't use hockey puck in front if flat jacking pad) to assure the extra sediment is drained too.

I always change the oil in mine before I put it away for the winter, but didn't this time because I only drove about 1,000 miles last year. When I take it out of storage I let it warm up for 10-15 minutes before driving it. I'll have the oil changed within a couple of days after that.

If the oil isn't at the end of it's life span and/or dirty I would take the car out for a drive of at least 20 minutes. This will get the oil hot enough that the moisture in it will burn off. Then change the oil while it is still hot. It will drain much better if it is hot. Fill up with new oil and let er RIP.

I would definitely recommend running it until it's fully warmed up, then draining it. The idea is to get all the nasty stuff back "in suspension" in the oil before draining it -- that takes advantage of the detergent properties of the oil. If you simply drain it cold, you will leave a lot of the contaminants and deposits in the engine.
