I guess I change my oil too often.

    I change my oil every 5K miles using Mobil 1 5W-30.

    I read an article on Edmunds that talks about every 7800 miles. I do believe that every 3K miles is ridiculous.

    Should I go with 7800 miles? If yes, how often should the filter go? The AC Delco PF-48 is a pretty inexpensive and changing it more frequently is not a big hassle.

    What do the other forum members think.

    i do mine every three months...needed or not due to low mileage driving.
    i think oil is cheap, i change oil on 4 cars, yet our 2010 crew still goes to the dealer.
    i only chamge the filters though, 3 times a year, not 4 times.
    i agree that changing it frequently is not a hassle, plus i get to check for other
    things underneath the kids' and neices' cars....Brian from Canada

    My HHR runs on Mobil 1 5w30, I am planning on running 8-10k on an oil change.
    My Colorado runs on Mobil 1 5w30, It will get changed every 3k because it gets ran HARD.

    The filter gets changed with the oil, I try to use Wix or Bosch and I always get a larger size filter than what is called for.

    It really depends on if you baby it, or drive it hard.

    Use synthetic oil and the Oil Life Monitor.

    IMO 4 times a year is overkill and you're just throwing money down the drain by changing good oil (I assume you drive ~15K a year).

    Right now I changing three times a year, but would like to do twice a year.

    I use Mobil 1 5W-30. With the new GM dexOS thing, you have to run semi-synthetic or full synthetic now.

    Agreed on the oil, but as far as filters, I only use AC Delco, I have found that the other filters (no matter how cool they look, or how much they cost) are JUNK.

    I drive ~15K a year, so I'm going to start changing the oil every 7500 miles.

    I chabge mine every 5k. I also use Mobil 1 5w-30. The filter is K&N. To me it is cheap insurance. I look at the old oil to see if things have changed. Such as signs of water or antifreeze and metal. Overkill yes! I do a lot of short trips (4 miles door to door to work). I average about 15k a year so changing the oil 3 times a year isn't bad to me.

    Wait, wait, wait! Am I understanding this correctly? You go one oil change and change just the oil and not the filter? I must not be understanding that. That is like taking a shower but putting dirty underwear back on. Filters are cheap. You can't be using mobile 1 and calling it "cheap" I know a few people that have cottages in Canada and Mobile one is nearly double the price there.

    I was talking to the service manager a few months ago. He said that with the new dexOS and the longer oil change intervals, they are seeing record numbers of broken timing chains on new trucks. He said that they are seeing them break at 30000-65000 miles. It seems to think that it is directly related to the longer 7,500 mile intervals. I also agree with the AC only filter. I will not use anything else. Sweet, this filter filters down to .000001 microns (exaggerated), to me that just increases the chance of the filter plugging and hopefully it bypasses like it is supposed to. I know a few techs that insist that the k&n, and the like, plug after about 1000 miles and basically your engine runs unfiltered oil through the bypass until you change the filter. I don't know if I agree with that thinking, but it does give me something to think about. GM designed the filter for what filtering they think is needed. If I wanted "More" filtering, i would add a bypass filter using an additional AC filter. I change my oil when the oil life monitor says to. But, I keep my eye on the miles, monitor %, and oil. I check my oil at every fill up. I look for level and condition/color. With my 2002 it would look the same when I took it out than when I put it in. In the 03 at about 75% life left it looked black like coal. In my 05 it start looking dirty at about 45% left/ I changed the oil the day I bought it. I now have driven 8000 miles since purchasing it. I changed it one other time with the monitor at 10%. Right now I have 50% left. So, I figure that I am getting about 5000 per oil change.

    I change my oil every 5,000mi and use a Puralator 12222 filter and pour Mobile 1 full synthetic back in.

    mine is done every 5k. my last two trucks i did every three. that may have been overkill, it may not have been. this truck seems to handle more miles between ok. i keep an eye on the oil, and it never looks to bad.

    yeah, i figure 3 filters for 4 changes isn't too bad as all the vehicles only get
    about 2 or 3000 miles on them between changes,,,,It's not the money to buy
    the filters, i just figure if others are vdoing 2 or 3 changes a year with filters
    that I would save the kids a few bucks and use 1 less filter a year??!!
    ....not sure if it hurts anything, but it hasnt for the past 10 or 12 years,

    ....no, not using Mobil one....use other name brands, and i am not sure if
    skipping the 1 filter would do any damage based on the low use it
    would get every 3 months----what do you think???

    My grandfather used to change the filter every 3,000 and the oil every 6000. He did it to a 1979 chevy station wagon with a 350. He sold the car to my dad. My dad drove it until the odometer had 500,000 miles on it. then the odometer stopped working and he drove it for another 5 years. He sold it to a scrap yard in 1995 because the body rusted out beyond repair.

    I change it every 3k... For some reason, my truck will read "Change engine oil" even before the 3k miles...

    Broken timing chains!!! Let me get this straight, if you change the oil every 7500 miles, you're more likely to break a timing chain? I'm having a hard time buying that.

    I was tossing around the idea of changing the oil every 8K miles, but changing the filter every 4K miles.

    I did not change the oil the day I got the truck, but every new vehicle I have ever had I have changed the oil at 1K miles and then 5K after that.

    As far as checking the oil color, unless the oil is the consistency of tar, you cannot judge the oil by its color or looks.

    That is what the service manager seems to think! I changed it the day I got it because I bought it used. The dealer had just done it but it had a MOPAR filter on it. :gasp:I am not trying to judge the viscosity or breakdown of the oil, I am merely looking at how dirty it looks. Jet black oil after 500 miles would concern me some. Looking at it at every fill up may give me an indication that something crazy is going on. If I check it and it smells like gas or went from looking new to looking black in 200 miles, I may want to do some investigating.

    x2 on what Pikey said about the timing chains, I have heard that before but don't know how valid it is.

    Every 3K miles is WAY overkill. You are just spending more money than needed.

    How is it way over kill? I have 13/14 year old tahoe with 155k on it. I don't use synthetic either. Its costs me 20/25 bucks every 3ish months... Big freakin deal...

    There are no credible experts/mechanics/etc. that recommend you change oil every 3K miles. That was a myth perpetuated by service facilities to get customers in more frequently to spend more $$$$.

    If you like changing the oil in your Tahoe, go ahead, it's still way overkill.

    I've been changing oil every 3k for every single one of my cars/trucks/motorcycles since I began owning them. And the way I see it, it never caused any problems by changing it too often. Its cheap enough, so why not?

    You did create this thread to get people's opinions right? Not to call anyone who doesn't agree with you "OverKill"
