"Hold my beer" moment here, got an idea. I've read a few extractor threads over the years and finally picked one up. It's the EWK 10 liter model, big, with hand pump OR pneumatic [air compressor] powered suction.
This idea would be especially useful to those who can only get about 2 qts of oil out through the dipstick when they try. Consider an example car doing 10-12k miles a year that you're using a quality full synthetic, perhaps 5 qts to make it easy. Let's say you plan on changing that 2x a year to be on the safe side even if you can probably get away with 1 change a year. So 2x changing, that's 10 qts a year. Instead of changing it 2x, why not just pull out 2 qts every 2 months [roughly] with the extractor?
I picked up a few fram ultras which are a 20,000 mile filter. And just to be paranoid, maybe do a full drain at 20,000 while I'm under there.
Who would want to do this? Anyone who doesn't like getting under their vehicle much but does want to know they have quality oil that's not ever pushed beyond it's reasonable life-span.
Why do this? For harsh engines, harsh climates, harsh driving/idling, etc, a fluid that's been in the engine for 5000-10000 miles is going to be a lot less "fresh" than one that's had 2 new quarts put in 2 months or maybe 2000 miles back right?
With an air powered extractor, I can take out 2 quarts in about a minute and cleanup is neater than pulling the pan bolt by far.
Anyone ever done it? Any reason why not to do it? I'm fully sold on oil changes from the top ever since getting he extractor and with how simple it is to pull out any volume I want this seemed like a natural progression. I think of it a little like the waverunner.. can't get more than 1/2 it's oil out at any one time ever. Thoughts? Thanks all!
