    Re: Oil Consumption

    Okay I just purchased my 06 SRX today with only 43200 miles on it. I was reading the post that the SRX burns through oil like drinking a glass of water. Can anyone tell me if there is a fix for this or if putting heavier oil will slow it down. I am thinking about taking a trip but I worried now that engine might give out or I will have to pull over every hour or 2 and check oil. This is actually my first GM I have ever owned and not I am wondering if I made a good purchase. Dealership I purchased from said oil was just changed 2 months ago but check the level DIC and it said it was at 9% i will be checking it in the morning. I am just hoping that this isn't a huge oil hog and I didnt make a huge mistake in purchasing it. Any help would be great. it is a Standard V6 AWD

    Thanks

    Congrats on the new purchase! Although I don't have an SRX, I have many GM vehicles (Vette, Trailblazer, GMC 3500 and Chevy 5500 RV) and have been reading oil consumption threads for years on the various forums. While I don't discount the posts, I also believe the oil consumption is somewhat dependent on driver behavior and is generally well manageable. It appears that those that spend time driving at higher rpm, particularly unloaded, see more oil usage. And in general, the oil usage is easy to control. In my Trailblazer (5.3L V8 with 120k on it) I commute to work 60 miles each way daily and check the oil only once per week on the weekend. Generally only have to add oil about every 3000k miles which works out to about once per month for me. Given that most people used to change their oil at that point, this really doesn't bother me. For what its worth, I follow the Oil Life Monitor and change my oil at about 10-12k miles. I think for your trip, if you follow the old adage to check the oil with every fuel fill-up, you'll be fine.

    Re: Oil Consumption

    I bought a 06' SRX in October. Currently it's using about a quart every 3k, which isn't as bad as some horror stories on this forum. What about those high mileage oils or even Marvell's Mystery Oil?? I read one SRX owner used it and stopped the consumption. I'm half temped to put it in my vehicle but it only has 40k and the oil is conventional not synthetic.

    Re: Oil Consumption

    If it ain't broke, don't fix it.

    Follow the oil change instructions (owners' manual) in terms of the exact motor oil and interval. If it will make you feel any better, change it more frequently, always with a fresh filter. By the way, 3K miles and the use of just one quart of motor oil is pretty good. I have NEVER had excessive wear or a motor-oil-related failure in 43 years of driving following the manufacturers' recommended oil change intervals. I'll bet their are a lot of others on this forum that have had the exact same experience.

    By the way, some years back Consumers Reports did a test on motor oils as well as a number of well known motor oil additives on engine-rebuilt NYC taxicabs.

    After testing everything under the sun (major brands, varying change intervals within the manufacturer specs, and a whole host of motor oil additives) their simple and unqualified conclusion after tearing the engines down after a zillion miles: "No measurable or reportable difference in engine wear or longevity prospects."

    Re: Oil Consumption

    With all this talk of low oil, I figure I'd check on Sunday. I bought it used (38.038 on speedo) back in October and oil had been changed. I checked it when I brought it home and the oil level was right at the middle mark on the dip stick. A month ago I checked it at work and it was low and when I got home I put in a half a quart. My driveway is not level so I didn't check to see if it was full. On Sunday and it just barely registered on the dip stick. Took 1 1/2 quarts to get it to the middle mark and the speedo was at 41,001. Thats two quarts in 3k miles!!! Guess I need to make a trip to the dealer.... :-(

    Re: Oil Consumption

    I had 20% oil life left and went to check my oil. It took two quarts and it's just barely on the dipstick now. I am going to have to run out to get more oil now. I am amazed, there is no way a modern engine should burn so much oil that it's unsafe to operate between oil change intervals.

    My LS6 and LSJ did burn more than 1/2 between oil changes. I am not sure how oil level would affect the timing chain, but I know from my motorcycle days a properly lubed and maintained chain will last longer.

    Re: Oil Consumption

    was hearing front end rattle for couple days before I checked
    when I checked for oil, nothing was registering on the dipstick (this is coming back from doing errands so engine is warm)
    thought maybe coz my driveway is on an incline so went to a more level road and still same
    added a litre of oil and it barely registered on the stick, put in 3 litres (about 3.17 qts before it got to mid-level on stick)
    no more rattle
    never occurred to me to check oil level when I first picked it up from the dealer (just about 4500 kms or 2796 miles by me)
    man, i was halfway to an actual oil change already, heh, dic still says 63% oil life, thought it should have increased after that, lol
    I'll be checking on that constantly now

    Re: Oil Consumption

    You really can't go wrong if you check your oil once per week. My '08 V6 uses no oil in daily in town driving. however, trips can cause it to use about 1/2 quart if the engine has to run above 3000 rpms to maintain desired speed.

    My 69 Daytona used about 1 qt in 800 miles. It used up spark plugs a lot faster when "cruising the main drag". Engine, 426 Hemi.

    Before my timing chains and engine cleaned (about 3-4 qts of oil sludge and a clogged pickup screen and leaks lol i was losing 3+ qts every 1k. Now Im down to 1 qt every 3k. Also did the pcv mod to get rid of the oil in the air intake.

    Re: Oil Consumption

    I have a 2007 V6 AWD and my consumption is around 1-1.5 qt. in 5000 miles. It is more than other engines I have run, but don't consider that excessive. There is never any smoke seen, so am not too concerned. It currently has 83K miles where I have done the last 40K and it has been consistent.

    Re: Oil Consumption

    My husband has to check my oil frequently and add a quart less than 1,000 miles. It's ridiculous that this is considered "normal" in today's auto market. We were told to just "deal with it" that it is "normal."

    Not 'normal' but far too common.

    These 3.6L engines are huge POS's and GM know it.

    I'd like the moderator to please remove this post. There is a serious problem with the 3.6 engine in the SRX. Everyone knows it. Many owners, me included, are putting in a quart every 1,000 to 1,500 miles. What is unclear to everyone on this forum is that no one actually knows the percentage of cars with the problem. It's a mystery and we will not know the actual facts. Its very difficult to continue to bring the car back to the dealer for the usage test unless you're retired. On the positive side, I don't know if the excessive usage is causing any additional problems, i.e. catalytic converter, etc. I have 125K miles on my car, still getting 22 mpg highway and the only negative is another $8 worth of Mobil 1 every 3 fill-ups.
