I changed the oil in my new 6.0 PSD HD from Ford at 1500 miles, 15 Qt.s of Synthetic and a $25+ filter....will be doin' that at least every 7500 miles and running the analysis.  And then there are the 17 qts in each of the CATS in my boat...I do those every 100hrs and at the end of the season...with the price of fuel this year, I will get 50 hours on the boat if I am lucky...all we do is run an hour out, anchor for the day and an hour back...oh yeah, that is about $100 in fuel.

The Bikes I do at 500 miles and then every 2500 miles and just before they go to sleep when the snow hits the ground.

That's what I was thinking, too.

Who said 6.0 PSD? Whoohoo, where there's smoke there's power. Gotta love them rolling home heating oil burnin' furnaces. Is yours stock or spooled up? Stock=Boring

As for Synthetic break-in vs petroleum based lubricants, here is my spin for the day. I use synthetic in everything I own, except break-in times. Because....I was told, the petroleum based product help with the sealing process of the gaskets, not the rings, etc. The synthetics do not allow the gaskets to "Swell". Which is why, most machine shops that offer assembly & dyno services, break the engines in with petroleum & water only (liquid cooled versions of course). When they say it helps "Seal Em Up" they are referring to the retention of fluids...No Leaks.

Michael, what'd you do on your SEEG? [smiley=nixweiss.gif]

RedFXR2, I think the Bimmers have a greater capacity than normal, don't they?  If the crankcase holds 7 or 8 quarts, that can make a difference in the recommended change intervals.  A guy I used to work with when I was in NC had a Porsche 911.  The crankcase in it held like 12 quarts or something and even though it was air-cooled, the change interval on it was in the 10,000 mile range.

I have always change oil in a new motor at 500 miles.  Ever sawed an oil filter from a new motor in half and saw all the sparkly stuff inside?  Sparkly stuff is usually good, except when it's running around in your oil.  There's always going to be some break-in that occurs on a new motor that will dirty up your oil, so in my opinion, it's better to get it out sooner as opposed to later.

Boring Right now...I only have 2500 miles since April...but it looks good sitting on the lawn!

Unfortunately, that is another myth that dates back to the infancy of the synthetic oil industry.  Back in those days, automotive gaskets were very low tech compared to what is used today (many were just plain cork gaskets), and the machining of the surfaces they sealed was nothing to write home about either.  Since the synthetics at that time were a lower viscosity (say 0W30 instead of 10W40), they would run through a poorly sealed joint a little quicker.  Thus another myth is born.

BTW, in case you think I'm nuts (which I am, but that's a different thread), this is from Mobil's web site:  

Mobil 1 does not cause leaks. In fact, new Mobil 1 was tested in dozens of industry standard and OEM tests to prove its seal performance. It is fully compatible with the elastomeric materials from which all automotive seals and gaskets are made. If an older engine is in good condition and does not have oil leaks, Mobil 1 provides the same advantages as when used in a new engine. ExxonMobil recommends taking measures to repair the leaks, then using Mobil 1. ExxonMobil also recommends following the automobile manufacturer's manual for the proper oil to use.

It makes sense, that todays gasket material is different than yesteryears...

WFP, 2500-stock miles...UGH! Spool that furnace up. It costs much less, with more reward to improve the performance of a force inducted diesel than our 103"s.

As for my SEEG,
HD Race Tuner
SE Pro 2:1
(Custom Baffle, many hours tuning for the best backpressure torque curve & sound)
Air Cleaner (with New Chrome Backplate, its about time HD released it)
Bike made 95hp, 105tq. No other mods.
If I go any further its gonna be big bucks, it will be heads, cams, etc.
For now, Im leaving it alone. The fun stuff is in the truck.

  The cross hatch on a new cylinder will be worn through in 35 miles or less. To get the best ring seating you need to press the rings against the cylinder walls during this time. The rings do not have enough inherent tension to do this. Combustion pressure forces the rings out against the cylinder walls.
 On a new engine to get the best cylinder seating you need to keep the cylinder pressure up until the rings are seated.
 I like to bring the engine up to temp, then run it wot from about 2500 up to 4500 through 2nd, 3rd and 4th. I will then ride it easy for about 5 minutes and then repeat. I do this at least 10 times.
 I learned a long time ago that the best way to make your new airplane engine use oil is to baby it for the 1st 3-6 hours. The way to make it seal well is to run it at full power for the 1st 3-6 hours. The HD engine, at least in my opinion is VERY much like an aircraft engine, (air cooled, pushrod, etc).
 Also the biggest danger early on is that of glazing. This occurs when the cylinder wall and rings get too hot. Dino oil will glaze, (cook), at a lower temp than full synthetic. So it makes absolutely no sense to break an engine in using dino oil and then switch to synthetic. You really need the synthetic in there during this critical seating period to prevent glazing.

Dammit, and we live in a town without a Krispy Kreme............

After that major flurry of expansion a few years ago, I didn't think there were any towns left without a Krispy Kreme.  

[TB]

Not only don't we have one in Boyne City, there isn't one within an hour of this place. [smiley=bigcry.gif]

[Twolanerider]

About an hour from here too.  What's even sadder is that the donut Gods tease us.  We get Krispy Kreme Sloppy Seconds in convenience stores.  Cold hours old Krispy Kreme when you know that, somewhere out there, there are warming donuts rolling down conveyer and calling your name.....   "Don, it's me, the donut, eat meeee."

[RedFXR2]

... somewhere out there, there are warming donuts rolling down conveyer and calling your name.....

[Michael]

Are we breakin in motors / engines on this post, or our waistlines?

I'll be 35 in October, I still have not experienced a Krispy Kreme.

You're giving me flashbacks to my single days in Atlanta.
