I'm an idiot (gas in oil)

Hillbilly_H · Nov 22, 2011

My H needed to be topped off with oil. So I followed procedure, grabbed my jug of non-detergeant and started pouring it into the funnel. I quickly realized I was pouring old gas (now varnish) I had put into an oil container becasue thats all I had to use at the time.

I"d guess that only about an ounce went in. Would you guys suggest to change the oil immediatley or could I get by since it was such a small amount?

Thanks

Depends on what you mean by a small amount. If say a cup or less you should be ok but if say a qt change it. Now for a question why the heck run a non-detergent oil when the newer oils are by far better and will not hurt you engine and probably help it

Don't worry about it...

An ounce of stale gas diluted in 6 or so quarts of crankcase oil (= 1 part in almost 200) won't hurt a thing.

You might want to label that container however(!)

For only an ounce , don't worry about it , it will evaporate in a few minutes of running. And switch to detergent oil next time it's due , that non det. will sludge up your engine .....

Not to worry mate, Heck if only an ounce may help things lol Look at those additives that supposeldy unstick sticky lifters and Rislone and all that junk where you add an entire quart.

Ive done things far worse

It has never had deteargent through it, there are gunk spots in the nooks and crannys that I've been told deteargent would loosen up and may damage things.

dhermesc · Nov 22, 2011

If your engine is that gunked up leaving it in there isn't helping it any.

old · Nov 22, 2011

Yep the stuff would loosen up and that is what the filter is for. Ya you might want to change the oil 2 or 3 times in say 40 hours of running time but after that the engine will be by far better off. Just think all that junk can/will clog up oil passage ways and no oil to a part means a part that will go bad or worse lock up the engine or throw a rod out the side of the block is say one of the rods stop getting oil

John M · Nov 22, 2011

Me personally, Id drain it, but that's just me. I would just feel better knowing I wasn't running the risk, albeit slight with such a small amount, of hurting the bearings. When I have one I don't know the history of, I drain, remove the oil pan, and have a look-see up inside the block, if its dirty/gunky. I pull the valve cover and lifter cover, get as much of the gunk out as I can, then run the cheapest oil I can get replacing one quart at a time with detergent, changing it every 20 or so hours until I get straight detergent oil in there. Yes, its a little expensive, that's why I use the cheapest oil I can buy when I do this. I haven't really ran across one bad enough in a few years now that warrant it though.

Dumb things, you have no corner on the market. I recall as a kid, my dad changing the oil in the Farmall A. With the hood and muffler off, he poured the first can directly into the exhaust pipe. Had to suck the oil out of the cylinders with a straw!

JRSutton · Nov 22, 2011

If you've ever had trouble starting an engine, you probably got that much gas in the oil just from cranking, cranking, and cranking with no fire.

It builds in the cylinders and seeps down past the rings.

Check the oil after running the engine for a while. If it's at all milky looking, swap it out. Otherwise I'm sure you're fine.

an ounce? .. i mighta added more..

think about the other solvent addatives to the oil like MMO or seafoam. those are pretty drastic solvents just like gas and like 10-12 ounces.

i wouldn't loose a moments sleep over it..

Here's a thought. The dual fueler's have petcocks on them to drain off the kero or distillate that ran past the rings. All you did was drain off about 1 quart and add fresh oil. The oil that was in there was already diluted, and continued to be diluted until you changed ALL the oil.

Do you really think that a bit of old gas in the oil is going to hurt anything? All gas, diesel, kero, or distillate will do is lower the viscosity of the oil. The old manuals said to add Kero to the tranny in really cold weather. I think you are fine.

Might most likely probably assumably etc.... it'll never hurt a thing....but for the cost of an oil change versus your peace of mind- why chance it?

I remember the time a employee filled my f-350 diesel up with gas, made it about 500ft and engine started knocking and spitting, and jerking..not fun

Had it towed to ford dealer, 1200.00 later, it was back on the road. I guess what saved it was winter and very cold that day and he did not go further than 500ft. and the tank was half full of diesel to begin with.
