Out of the blue my motor oil started to disappear... i've had a bad start one time when the motor was flooded, then iv notice my oil started disappearing by looking at the dipstick. Theres no blue smoke coming out the tail pipe , so i'm lost...

Anyone with 15w40 experience?
BTW once i noticed this , i started pouring 10w40 instead of 10w30 in....(if thats any help)



luckily i noticed this before a catastrophic disaster would of happened

Check your coolant. Does the color look right?

color seems ok, but i have noticed that its very slowly disappearing from my overflow container as well... and iv just replaced the LIM/UIM gaskets about a year ago.

why? out of curiosity.

The oil has to go some where. It'* either dripping on the ground, going in to your coolant, or burning in the cylinders.

How about pooling on top of the LIM. If you don't apply sealer to the LIM bolts, the oil can wick up them and pool on the lim.

My car seems to be doing the same thing. I can't figure it out.
I'm losing coolant, I know, I can see it dripping from a hose [see my other post]
The coolant loss seems to be less severe than it was before, I think my shop might have fixed it for me if it was an easy fix. But the oil seems to be just disappearing.

I know it'* not burning oil or coolant, I checked the exhaust. My guess is it'* leaking out of the bottom somehow. I can see oil all over the bottom, but I assumed that was from when the oil cap blew off and oil went everywhere [last year'* disaster]

Do you seem to have abnormally low oil pressure? I do, and I think it might be because i'm losing oil. But to me it'* not a big deal, I just keep an eye on the pressure, check it every so often, and make sure I keep a few quarts in the trunk. The way I see it, if it'* just leaking oil, it'* cheaper to add it every few weeks than fix the problem.

By the way, what color is the coolant supposed to be? After it'* been used for a while..

If you have DEXcool in the system it will be a pink color.

When did dex change coloring from orange to pink?

I don't use DEXcool, there'* some sticker talking about it but I just went with regular 50/50 coolant. I hope that'* not bad O_o I heard some bad things about what dexcool does to the engine so I never used it. Not sure if it'* true or not, but I just said better safe than sorry.

Pink orange, what ever. Looks pink to me.

Don't believe the DEX horrer stories. How ever. If you added any other coolant other then DEX when you have DEX in the system it will sludge up and turn black. You will need to drain and flush the system.
