    Check Oil Level message in DIC

    On my 04 dhs approx. between a month and two months after getting an oil change my check oil level comes on and sure enough my oil is low. Are our cars known for burning oil quickly or do I have a bigger problem I need to look into?

    2 years here and you've never read anything on oil consumption? Yes, some oil consumption is normal. If it's excessive, some WOT will likely help (this is in the Technical Archives).

    By the time you get the oil level warning, you're 2 quarts low... I take it you aren't checking your oil level regularly?

    Re: check oil level

    Sounds like this is a car that has to scream "Help !" before the hood gets opened.

    , You're supposed to open that hood every week and look at, measure, touch everything.............. or one night, the thing you didn't check is going to crap out and leave you stranded in the boondocks. Do you manually check your tire pressures at least monthly ?

    Please go way up ^^^ to the top black bar and study the entire Cadillac Technical Archive. There are two articles on oil, oil life, and consumption that you NEED to read. GM says an acceptable oil use rate is one quart in 2,000 miles. Some Northstars use more oil than that, most use a lot less.

    Re: check oil level

    I take it by "two months after getting an oil change" you did not do the job yourself. Do you know for a fact that they put the proper amount of oil in it?

    Yes I'm positive they put the proper amount which is usually around 6-8 qtz. No I did not do my own because currently where I live (condos) my HOA does not allow car repairs on property so its easy to go get it done down the street from my house.

    I check my fluids often but I'll admit I have been slacking a little because I definitely haven't been checking my fluids weekly.

    Around 6-8 quarts? If they only put in 6 quarts, you're starting out 2 quarts low.

    Yeah, the proper amount is 7.5 quarts from empty, half way up the hash marks on the dipstick (xxxxxXxxxxx).

    And 8 quarts is too much ... 7.5 is the spec ..I check mine every time I get gas . I never trust oil change places and would check the oil level my self before I moved the car or paid for the oil change.

    Re: check oil level

    I believe the owner's manual calls for 5w30. Any reason not to run something like 10-40 or thicker? Might slow down the oil consumption.

    It won't affect oil consumption. Use 10W-30 if you feel the need for a thicker oil, but any -40 weight is too viscous at operating temperature

    Yeah, that ^^^

    The Northstar engine oil lubricated bearing clearances are not set up for -40 oils in any sort of passenger car duty.

    Yeah I think I'm going to start using 10-30 vs 5-30 to slow down the consumption. My car now has 140k on it so that may be another reason for the faster consumption. And after all of the trouble I'm going back to doing it myself. Hey has anyone switched to synthetic?

    10W-30 is only more viscous when the engine is cold. It will make no difference.

    Yes, there are members using synthetic.

    Re: check oil level

    Yeah, that.

    The 5W-30 theoretically makes it easier for the engine to start and run during warmup - when the oil warms to about 160 degrees, any xW-30 oil is all the same viscosity. 5W- also gives a theoretical gas mileage increase when cold/cool (less drag in the engine rotating machinery) so that allows a tiny "improvement" in CAFE to satisfy the EPA for a while - until the bureaucratic fools come up with yet another "save us from ourselves" jackass idea.
