What the hell is going on??

[bfisher88]

So I did an oil change yesterday. Added 5L of ELF NF 5W40. Indicator just came on that said engine oil level is low. Checked the oil, it was pretty much empty. Checked under the hood and under the car, no oil had been leaking, everything was dry? What the hell am I missing?

[manguyen]

u drive a 3.0 or 1.8?

[bfisher88]

3.0

[SeKKeY]

i had to replace my oil level sensor, located at the bottom of the pan

[bfisher88]

I checked the dipstick as well... Bone dry except for the end of it....

[Ill 3.0]

3.0 takes about 6.5L...

[bfisher88]

So why would the indicator and the dipstick be showing pretty much empty when there is 5 quarts in there?

[SeKKeY]

because your oil sensor isnt sending the signal?

[AudiA4_20T]

that 1.5 quarts will make a huge difference, fill it up to the full and wait to see if it eats any

[bfisher88]

Yep that was it, i'm retarded and I needed that extra quart and a half. Now, I used a normal 5w40 instead of full synthetic, to get that last quart or so. Should I worry about it or just run it like it is?

change your oil again, the two oil won't mix. it's not good.

[pondside36]

oh man.. Like Maverick said change your oil

[lookaught]

What the hell are you two talking about? He added a little dino to his car, there is no NEED to change it all, unless you really want to waste the money on 6.5 quarts of new synth.

The additives are slightly different, but it won't harm the engine and it will mix together just fine. How do you think they make blended oil? Magic?

Dont waste your money, just change your oil in 5k or whatever interval you use and dont sweat it. Everyone here is paranoid to an extreme.

the 2 oils mixing with create more air bubbles and "foam" when the manufacture creates semi syn they do NOT jsut take full syn and non and put them in the same can.

change your oil but its your call, after all, its your car.

Not to be an ass but can you cite some evidence that topping off synth oil with dino causes increased foam and thus engine problems. I just can't believe that he is risking his motor by having 23% dino oil, I have never, ever seen or heard of an issue like this, and people mix oils all the time... some on purpose every time they change their oil and their cars run for hundreds of thousands of miles.

Obviously the chemical engineers dont just pour two shelf oils together to make their blended variety, but a blanket statement that "they dont mix" is a quite the overstatement. Im not a petroleum engineer, but this isnt like mixing oil and water....

Thanks for the responses guys. I'm going to change the oil, but I won't be in a huge rush to do so. I'll place an order for more oil here pretty soon. I think I'll go Total Quarts 9000. Little bit cheaper and pretty much the same thing as ELF right.

He may be fine for a while but mixing oils unless you know the make ups of both is not a good idea...period.. oils from different companies contain different detergants.. IE Shell oil has a much higher detergant factor than Mobile oil, just how they do it. So the bi-product of mixing a synthetic and non can produce foaming, sludging, varnishing... I am an engineer... put the oil recommended or similar to OEM specs or do what you wish and see how much you get backed if something happens with your engine..

Also when we switched from Mobil to Shell on our Large Medium speed Diesels and reduction gears we had to pump sumps dry and then wipe clean to prevent contamination... granted our engines are much smaller with a lot less horsepower, it is still a concern when mixing two different oils..

Just purchased 15qt. of Total Quartz 9000 5w40. That should be enough Thanks for the responses guys.
