    Hmmm, interesting.

    Cost cutting I assume, much like the cabin filters in the early GMT-800 stuff then dropped in later years.

    Re: Cadillac 2006 SRX funny engine noise

    My funny engine noise was indeed the oil. Cross country trip must have done it. Thanks so much for the responses. We filled it up...got some good octane gas in her and no more sounds-thank you so much for making me aware of how to take care of my car. Never would have thought I was low on oil-no oil pressure light, no check engine light and all diagnostics say everything was fine. Car shifts correctly now too. Thank you so much!!!!!!!!!

    I'm glad the sound went away and it drives OK. But, I hope there wasn't any permanent damage. Check the threads about timing chain symptoms and be on the lookout for that problem. It seems that problem often starts due to driving with low oil level.

    My last oil change I added Bardahl No Smoke-Stop Leak Original Formula to the oil. After 10% of oil life used I show no signs that I burned or lost any oil. I was adding about 2 quarts per oil change previously. I have a V-6 with 72,000 miles. You know what they say about the phsyc factor after a fluid change everything sounds and runs better. Well the car feels more poweful and runs smoother. In my opinion...for now anyways....

    Add oil until the level is midway on the oil level indication part of the dipstick before you drive anywhere. As said above running the V6 VVT engine low on oil will screw it up.

    The fact the engine requires a full synthetic oil is the reason an oil change is expensive. Most oil changers charge quite a bit more for Mobil 1!

    WalMart continues to be my cheapest source for Mobil1 (I add a quart or so frequently to my '06 V6). I've become convinced that Sea Foam and Marvel Mystery Oil
    are worthwhile addatives, so I'm looking forward to hearing how Bardhal works out as well, Hope everyone keeps up with these marvelous posts; I love these forums.

    Blessings.

    I still joke that my 3.6 SRX was my 2-cycle Cadillac. I kept bottles of Mobil 1 on my workbench. The only engine of mine that needs the same level of oil monitoring is the 1985 Kohler in my John Deere tractor.

    Re: Cadillac 2006 SRX funny engine noise

    Valve timing could be off slightly due to poor quality gasoline. With rapid changes in temperature, there is also possibility of moisture in the tank, which can make the engine run rough. You could try adding gas cleaner/drying agent or fill up at another station and see if the problem goes away.

    How is it that poor fuel can change valve timing?

    This is an out of oil issue.

    thank you, thank you, thank you, for your reply. My srx had the same symptoms as above, with 60% useful life showing on the dash. I decided to take the advice you gave just in case and was shocked to find a bone dry dip stick. don't know where the oil went? Hopefully I changed the oil before it's too late.
    again thank you.

    Get use to adding and keeping a gallon of oil in your truck at all times. I check it every other day just cause I absolutely do not trust this engine.

    Where is the oil going? Are the spark plugs really gooped up when they're changed? Is it leaking somewhere else?

    Good place to look as the spark plug tube seals most of the time Dry out crack and leak but I'm not sure this his total issue as he is losing a good bit of oil and only so much will be in that tube.think he has other issues.
