    If you have a DI engine and don't think you need a Catch Can - LOOK AT THIS

    Just did an oil change.

    The oil change message came on at 4500 since the last one. No oil used during the 4500, but I probably could have added about 6oz (+/-) judging by the dipstick, which I have watched religiously after reading some posts here about oil usage.

    When I drained the RX Catch Can I installed at the last oil change, I was pretty shocked.

    There was a little over 4oz of oil mixed with condensation that drained from the can.

    This would have been ingested into the intake plenum, coating it and the intake valves.

    It cannot be cleaned with additives since the DI engine does NOT pass fuel over the intake valves. Just air.

    I will guess that the Catch22 (pun intended) is that it will void the drivetrain warranty.

    Re: If you have a DI engine and don't think you need a Catch Can - LOOK AT THIS

    Hey guys,

    With hundreds of thousands Cadillac CTS DI sold, not to mention other DI brands/models, and now many thousands driven >100Kmi, I can't help but wonder how few of those vehicles actually have catch-can(s) installed? So how perilous is oil ingestion, anyway? How many miles/km driven before DI engine performance and/or fuel economy degrade to the point of owner awareness? Or, is excessive oil consumption the only discernable symptom?

    BTW, my DI engne was rebuilt and later replaced by a brand new LLT engine due to excessive oil consumption caused by factory defective out-of-round cylinder bores - GM, my Cadillac dealer, and GMPP agreed. Was my original engine a one-off? Not likely, in my opinion; thus many reports of excessive oil consumption for 2008-09 CTS, both DI and PFI engines.

    Just my 2¢.

    Also, driving longer miles where your engine gets good and hot may make a difference, too. Driving fewer miles and just a couple of miles to the store, for instance, the moisture in your engine won't be removed by the heat.

    Which RX Catch Can did you get? I'm conflicted on which one to get. I'm just wondering if the $200.00 one will suffice, or if I need the $300.00 one.

    I got the less expensive one.

    I must be very lucky as I have a 3.6DI that uses virtually no oil between changes and gets 19.8mpg combined. I don't drive it like I stole it, but I don't baby it either.

    I have a 43 yr old Corvette and a Harley that I do all my own wrench-turning on.

    After seeing this, a catch can of whatever brand is a no-brainer. The non-DI engine doesn't have this problem because an occasional bottle of cleaner or top-tier fuel makes it a moot point.

    Is the 3L direct injected?

    I can't help but think that these contaminants come out during an oil change. I think if you want an oil catch can , you should be able to buy one and put it on. But if you don't have one, just like the millions of cars on the road, you will be fine.

    I'm not even sure. I'll have to look at that.

    ^ LOL ! There are very few collectible `71 H-D`s ( Shovelheads) You need to wish for `65 and older. (Panheads)
    On the other hand "chrome bumper" Vettes are gaining in value quite steadily.

    But, I certainly get your drift

    Couldn't agree more. I don't know if they come out during an oil change, but they can't be that important given the number of people that don't have them.
