Burning 3.9qts every 1000 miles

You REALLY should put a after your comments like that.
Somebody might take it seriously.

 

i know, i'm a bad boy

 

As it’s been said, there is no low oil light. What you see is the low oil pressure light. It will be interesting to see how long the engine lasts. Please keep us informed and let us know what the mileage is when you throw a piston.

 

Look for my post on this, it may be of some help.

I would recommend a little 2 cycle and mmo in the gas tank. I would also run Run e15 to help keep things cleaned out.

Try 5w40 or 10w30, if it runs rough on those grades add mmo to the gasoline.
It’s running rough because it’s chugging oil.

There may be life left but I would just use cheap heavy oil.

Letting it get down to the "low oil pressure" point that often certainly is not good for it.

The only good news I see in this story is:
If you are adding almost 4 quarts every 1000 miles, you theoretically should never have to do an actual oil change.
My guess is that it will die completely before you really need a new oil filter.

 

I didn’t see a compression test, seems like engines should be available at the junk yard, cheap. If you want to go that route.

 

I see no more comments from the OP.

 

I have to say...I don't think the odds are forever in your favor here.
I pretty much think...your engine is shot.

Without being too snarky, I would ask, if you discover the vehicle is burning Oil at very high consumption rate? Why would you wait until the vehicle threw a red triangle of death code? Until it was "empty"? The common reaction is to check it more often and NOT let it get low.

Because if you had a problem, each time the engine is run down to that level of emptiness, it only exacerbates the damage.

Given your symptoms, and description of the problem and reaction....I don't see how your engine could NOT be shot.

But?

I could be wrong.

 

It would be interesting to see the compression numbers. I wonder how much blowby it has

Engine Blowby

 

Linked here: Oil consumption...what I did to correct it.

@Aztechmaster Since you haven't updated the above thread in some time, can you please post your current rate of consumption?

And not to mix up threads too much, but I've read that modern ATF doesn't have large quantities of detergents like back in the day.

Any truth to that, or additional thoughts?

 

That's good to know. However, you're still replacing and adding oil at a alarming rate.

If you are losing oil at the rates you are saying, despite not seeing a leak or smelling anything..the oil is "going somewhere".
IMO if it's not a leak, the other alternative is the vehicle is burning the Oil.
If that is the case, I would think you'd see significant smoke.

 

This thread is awesome............

If the car burns through a quart of oil about every 250 miles....that's one quart of oil for every 6 gallons of gas. (24 quarts of gas + 1 quart of oil) Ah - ha.....you have a 1.5 liter 2 cycle engine!!! No,, actually that's even more oil than most 2 cycle engines mixtures...

 

I’d be about the right mix to run this:



Hard to believe an engine will ALLOW this condition to occur.

 

Huh, I was thinking the same thing, lol.

Try a leakdown test too.

Be prepared!
