Item 1(a) Name of Issuer:

     Sunoco Logistics Partners, L.P.

Item 1(b) Address of Issuer's Principal Executive Offices:

     1735 Market Street; Philadelphia PA 19103-7583

Item 2(a) Name of Persons Filing:

     This 13G is being  jointly  filed  by  Tortoise  Capital  Advisors  LLC,  a
Delaware limited liability company ("TCA"),  and Tortoise Energy  Infrastructure
Corporation, a Maryland corporation ("TYG").

     TCA and TYG have entered into an  Agreement  Regarding  Joint Filing of 13G
dated  August  31,  2005 (the  "Agreement")  pursuant  to which TCA and TYG have
agreed  to file this 13G  jointly  in  accordance  with the  provisions  of Rule
13d-1(k)(1)  of the Securities  Exchange Act of 1940, as amended (the "Act").  A
copy of the Agreement is attached hereto as Exhibit A.

Item 2(b) Address of Principal Business Office or, if None, Residence:

     The principal  business  address of both TCA and TYG is 10801 Mastin Blvd.,
Suite 222, Overland Park, Kansas 66210.

Item 2(c) Citizenship:

     TCA  is a  Delaware  limited  liability  company  and  TYG  is  a  Maryland
corporation.

Item 2(d) Title of Class of Securities:

     Common Units

Item 2(e) CUSIP Number:

     86764L108

Item 3 The Reporting Person is:

     TCA is an investment adviser in accordance with ss.  240.13d-1(b)(1)(ii)(E)
and TYG is an investment  company  registered  under Section 8 of the Investment
Company Act of 1940 (15 U.S.C. 80a-8).

Item 4 Ownership:

     TCA acts as an investment  advisor to TYG, a closed-end  investment company
registered  under the Act.  TCA, by virtue of an Investment  Advisory  Agreement
with TYG, has all investment and voting power over securities owned of record by
TYG. However,  despite its delegation of investment and voting power to TCA, TYG
may be deemed to be the  beneficial  owner  under Rule 13d-3 of the Act,  of the
securities it owns of record because it has the right to acquire  investment and
voting power through termination of the Investment Advisory Agreement. Thus, TCA
and TYG have  reported that they share voting power and  dispositive  power over
the  securities  owned of record by TYG. In addition to acting as an  investment
advisor  to TYG,  TCA also acts as an  investment  advisor  to  Tortoise  Energy
Capital  Corporation,  a closed-end  investment company registered under the Act
("TYY").  TCA, by virtue of an Investment  Advisory  Agreement with TYY, has all





investment  and voting power over  securities  owned of record by TYY.  However,
despite its  delegation of investment and voting power to TCA, TYY may be deemed
to be the  beneficial  owner under Rule 13d-3 of the Act, of the  securities  it
owns of record  because it has the right to acquire  investment and voting power
through termination of the Investment Advisory Agreement. Thus, TCA has reported
that it shares voting power and dispositive  power over the securities  owned of
record  by TYY.  TCA also  acts as an  investment  advisor  to  certain  managed
accounts.  Under contractual  agreements with individual  account holders,  TCA,
with respect to the securities held in the managed  accounts,  shares investment
and voting  power with  certain  account  holders,  and has no voting  power but
shares  investment power with certain other account  holders.  TCA may be deemed
the  beneficial  owner of the securities  covered by this  statement  under Rule
13d-3 of the Act.  None of the  securities  listed  below are owned of record by
TCA, and TCA disclaims any beneficial interest in such shares.
