Do any of you save and reuse your short OCI oil?

[zerosoma]

In the upper midwest we get colder temps earlier in the year, and I changed my Hyundai's oil to Valvoline 10w40 about 2 months ago. There's less than 1k on it and I'm thinking of draining it at the end of the month. Obviously there's additive left and a good amount of oil that can be used from this short fill. Do you ever reuse oil you've drained in an otherwise pretty clean engine?

No

Exactly Oil is pretty cheap, especialy something like pyb

Cross contamination would be a huge issue. The risk isn't worth saving just a few bucks.

I don't because I would not put such a heavy oil in my car knowing winter was coming. Actually I would not put such a heavy oil in a regular modern car at all, unless in emergency.

According to the manual it's fine...



I wouldn't reuse it in any of my vehicles. Thats just me. But I'd use it in my moms oil burning E150 as top up.

No but I used to give it to a neighbor with an oil burner Chevy van. He used it at a rate of about a qt. every 200 miles IIRC.

I remember a friend had an old Toyota that burnt a lot of oil. He would come down to my workshop and top his car up with oil from my waste oil drum. IT never got an oil change. That car kept on running for years.

I drained some very expensive Selenia that I did a UOA on, TBN 7, no contaminants. I was planning to keep it for something else but when it came time to fill another vehicle I grabbed a new jug and the Selenia when to waste.

Not any more.

I do have two anecdotes:

I had a Corvair with a presumed cracked piston that got ~15 miles per quart on used Delo 15w40 or ~45 miles per quart on used Aeroshell 50.

My Dad doesn't really buy the whole oil change concept. I had a Mazda for years which I changed with Napa 10w30 every 3,000 miles like clockwork. One time I asked my Dad if he would like me to save the oil in a clean container for him to use for top ups since it came out clean. He said "no, don't bother". Some time later he used filthy sludgy contaminated with moisture waste oil straight out of my plastic collection jug. It wiped out the rear main seal on his Ford 300 within a week.

i put it in an old lawn mower that uses lots of oil.

 

[kschachn]

Yeah, umm no. But like some others, I had a friend who used the drain oil from his Porsche in his Buick Something that was his winter car.

Your old lawnmower used a lot of oil because you used old oil in it

Why not just use 5w-xx or 0w-xx year round? Then you won't waste oil by disposing of it prematurely. If you use an extended drain oil/filter (the 1yr/15K variety like Mobil 1 EP), it will cost less per mile than conventional oil if you are an average or high mileage driver and if your car does not consume much oil.

 

[kschachn]

Yeah, there was this guy in college who commuted from home. His car (a brown and forest green, brush-painted something with a checkerboard vinyl top) burned so much oil that he had to put a quart in at home, then at school for the return trip. That was about 15 miles too. He carried cases of K Mart oil in his trunk.

Exactly. Change it once a year (most people) and do it when you don't have to get under a car when it's cold outside.

Several years ago I gave my 10K M1 to a fellow worker to use in his mid 70s Chevy V8. He changed his filter twice a year, but in the 4 years he did this, he never drained the pan. The engine ran fine when he finally sold it. He coined the phrase" Got any M2 for me".

If its not worth putting new oil in, its not worth driving. And I drive some pretty old cars with high millage.

Recycling it at the auto parts store is a good idea instead of giving it a chance to get contaminated.

If I were to change the oil early in one vehicle, I wouldn't go through the work to put it in something else. The only time I would ever dump old oil into a car is if it were only a field car needing oil. The comment about the someone dumping in a quart every 200 miles made me smile. I thought my Camry's 1200 miles per quart was something to be concerned with. Guess not.
