I don't wish to start one of those break in oil wars but with today's oils
and good filters most of this is not necessary. At 3,000 miles those pistons
have cycled at least 9,000,000 times. (~3,000 revolutions per mile in 4th
gear X 3,000 miles). If those rings haven't seated by now they won't get
better tomorrow. Also, unless using a specific break in oil to speed up the
"break in) process modern conventional oils still have a robust anti wear-
friction package so not that much difference there. The varying engine speed
and reduced load thing may be to help form the carbon ridge and seat the
rings in the piston lands. That I have seen in a number of owner's manuals.
I do believe in lower cost oil for the first fill and a fast change. Mostly
because no matter how hard we try there will be some unwanted stuff in a
rebuilt engine. Also if there is a problem I don't want to throw away the
more expensive stuff. For oil viscosity even on rebuilt engines I still pay
attention to the original chart. Note that when you look at oil temperature
specifications these engines were labeled for maximum oil temperature of
168F. I have yet to see any of these engines run there in summer. 190-210 is
about the best I see on any with an oil temperature gauge.

Dennis,
What are your thoughts in using Mobil 1 15w-50 in my Porsche 1973 -2.0
engine ? I have always used 10w -30 regular oil in it. The engine has about
only about 3000 miles on it. It is a rebuilt 2.0 engine. Haven't really
driven it much. My plan is to work on getting it running again in the
spring. It has sat in my barn for unfortunately several years after I
rebuilt and refinished the body, the engine etc.

I would consider that Eng' to be a "NotBrokeInYet" Eng' so here is
My 2cents ~ the BreakIn Routine I Adhere To ~
For an H2OBoxer ~ Or Other OldTech Eng'
Conventional/Dino 5w30 ~ 1st Hour ~ then drain it
1000-3000RPM ~ Trying not to stay @ any 1 RPM for vary long
Conventional/Dino 5w30 ~ 0 - 1000 Miles ~ then drain it
Not over 4000RPM ~ Trying not to stay @ any 1 RPM for vary long
Conventional/Dino 5w30 ~ 1000 - 2000 Miles ~ then drain it
Not over 4000RPM ~ Trying not to stay @ any 1 RPM for vary long
Conventional/Dino 5w40 ~ 2000 - 4000 Miles ~ then drain it
Not over 4000RPM ~ Trying not to stay @ any 1 RPM for vary long
Conventional/Dino 5w40 ~ 4000 - 7000 Miles ~ then drain it
Not over 4400RPM ~ Trying not to stay @ any 1 RPM for vary long
Conventional/Dino 5w40 ~ 7000 - 10000 Miles ~ then drain it
Not over 4800RPM ~ Trying not to stay @ any 1 RPM for vary long
FullSynthetic 0w40 or 5w40 ~ 10000 - 14000 & every 4K
after that until My OilPressureGauge tells me I might want to think about
Upping to a *w50 or
an Eng'Rebuild
For a ModernEng' ~ Subi or TheLike ~
Same as Above Up To ~ 2000
Conventional/Dino 5w30 ~ 2000 - 4000 Miles ~ then drain it
Not over 4000RPM ~ Trying not to stay @ any 1 RPM for vary long
Conventional/Dino 5w30 ~ 4000 - 7000 Miles ~ then drain it
Not over 4400RPM ~ Trying not to stay @ any 1 RPM for vary long
Conventional/Dino 5w30 ~ 7000 - 10000 Miles ~ then drain it
Not over 4800RPM ~ Trying not to stay @ any 1 RPM for vary long
FullSynthetic 0w30 or 5w30 ~ 10000 - 14000 & every 4K
after that until My OilPressureGauge tells me I might want to think about
Upping to a *w40 or
an Eng'Rebuild
ALSO ~ Since that Eng' HasNot been Run in a while I would Drain the
OldOil Before Any Attempt to Start It Up ~
