    Car and Driver recently had an article detailing their 40k miles of experience with a GT350. They went on and on about how wonderful the car was, and honestly I agree with that assessment.

    They briefly mentioned how much oil they had to add between oil changes over the 40k miles: 21 quarts. No other car they have tested has been anywhere close to that much oil consumption.

    I wondered why that did not dampen their enthusiasm for the car.

    I also wondered what their break-in procedure was.

    Patience comes with age, so I was able to resist getting too crazy until 1500 miles. I do not have an oil consumption issue so far with approximately 14.5k miles. Oh, and I don't baby it anymore.

    They alluded to their break-in here: "Obeying the 1000-mile break-in period by not revving the engine sky-high took painful restraint. But once we got past it, the GT350 clicked off a zero-to-60-mph time of 4.2 seconds and ran the quarter-mile in 12.4 at 118 mph."

    They report 21.5 quarts in 40,000 miles. That's one quart every 1860 miles. Much, much better than some. And they admitted they drove it pretty aggressively.

    Glad to hear you're at 14.5K with no issues!

    Waiting to return to the US next week to pick it up at the dealer. It has 8 miles on it now.
    Think I’ll obey the manual, and past the 100 mi mark I’ll progressively increase the RPM before shifting, but in lower gears to limit the load on all mechanicals (i.e. not run up to 7500 in 3rd or 4th gear).

    Break-in Report:
    1003 miles on it. This is what I did:
    - First 100 miles totally babied it, and did the recommended Brembo break-in, doing 30 moderate slow-downs from 60 to 30 mph with a 1/2 mi of cool down between each, which pretty much got me close to 100 mi.
    - Then followed the following RPM limits procedure, up shifting and rev-match down-shifting frequently.
    -100-200 mi @MAX 3500 RPM
    -200-300 mi @MAX 4000 RPM
    -300-400 mi @MAX 4500 RPM
    -400-500 mi @MAX 5000 RPM
    -500-600 mi @MAX 5500 RPM
    -600-700 mi @MAX 6000 RPM
    -700-800 mi @MAX 6500 RPM
    -800-900 mi @MAX 6500 RPM
    -900-1000 mi @MAX 7000 RPM
    Haven’t actually gone 7500 RPM yet, but varied the RPM the whole time during the 1000 mi, and did do some WOT up to the above RPM limits in each tranche of break-in, and in the last 100 mi did a couple of 3300-7000 runs (1st, 2nd, & 3rd...7000 in 4th is just too fast...110-120 mph).
    Results:
    - Oil consumption appears to be nil, measured 16 minutes after shut-down. The oil level has always shown at the top of the top hole (always measured 15-16 mins after shut-down, and always with the hatch marks towards me). I found that even with the driver’s side catch can installed, you can easily pull the dipstick from behind the cross brace, and after wiping it clean reinsert by locating the hole looking from the front of the cross brace.
    - Driver’s side catch can bone dry
    - Passenger’s side catch can was about 9-10mm of oil, at the deepest point. The first 3 bunched-up paper towels collected 95% of it, and then dried it bone-dry with a 2nd set of 3 paper bunched-up towels.
    - No coolant or brake fluid consumption apparent.
    FYI, also got the PPF done at 300 mi. $1900, but worth it to ward off the paint chips.
    Now, if someone can tell me how to ward off the brake dust, I will be indebted!

    As much as I loved the stock brakes, the brake dust made Saturday wash day miserable.

    Rjay, I find the OEM barkes to be incredibly good despite the brake dust. Have you found the Z29 replacement pads to be equally strong/effective?

    Why doesn't everyone just follow what's in the supplement manual? At least the way I'm reading it... Go easy on it for the first 100 miles. Then go have fun with it. You really can't get too aggressive on the street anyway. Typically short bursts before you run out of room, run into traffic, or blow past the speed limit. Performance engines should see full rpm and decent loads as it's breaking in for everything to seat properly. The supplement also says don't do any track days until you have at least 1000 miles. Which is logical as it's sustained high rpm and WOT for 30 mins or more at a time versus quick bursts on the street.

    I’m aligned with your statement, and with “regular” motors, I’ve driven it like I stole it straight out of the dealership. But this is not a regular motor; it’s a FPC that is prone to more vibrations than a CPC motor, and with any rotating assembly, vibrations are not a good thing, which is likely why the supplement manual states what it does.
    So to answer your question, maybe because of other member’s FPC motors have blown up? I paid attention to the 1000 mi specified in the supplement manual, and added the suggestion from other members to gradually increase the RPM as the mileage increased to allow things to seat at higher rpms and load progressively.
    The supplement manual literally says;” Your vehicle requires a break-in period. Drive your new vehicle at least 100 mi (160 km) before performing extended wide open throttle maneuvers and at least 1,000 mi (1,600 km) before performance or competition conditions.
    Note: Vary your speed frequently in order to give the moving parts a chance to break in.”
    So, what is a “performance” condition? Is it maybe going WOT from ~3300 to 7500 RPM through 1st through 3rd gears? Furthermore, I interpret the additional note as “engine speed” as well as overall speed, hence how I broke it in, and I think the fact the note is after the 1000 mi statement to mean that the “varying speed” applies to the 1000 mi and not just the first 100 mi.
    Let me ask how you broke yours in, and how many miles it has on it now, and what oil consumption or any other conditions you’re experiencing? Does the procedure I followed make you nervous because you hammered the crap out of it just past 100 mi?
    I’m not trying to be contentious or combative; just trying to understand the source of your concern for how I broke-in Enchantress.
    If you did hammer it to 7500 rpm just past 100 mi, have no oil consumption or any other issues and have a considerable mileage on the car/engine, I’m very happy for you!

    The OEM brakes are great, it's the brake dust that kills the experience.

    I would say the Z26 pads dropped the brakes from excellent to very, very good.
