                      Report of Independent Auditors


Plan Administrator
The BP America Savings and Investment Plan
Cleveland, Ohio


We  have  audited the accompanying statements of net assets  available  for
plan  benefits  of  The  BP  America Savings  and  Investment  Plan  as  of
December  31, 1998 and 1997, and the related statements of changes  in  net
assets  available  for  plan  benefits for the  years  then  ended.   These
financial statements are the responsibility of the Plan's management.   Our
responsibility is to express an opinion on these financial statements based
on our audits.

We  conducted  our  audits in accordance with generally  accepted  auditing
standards.  Those standards require that we plan and perform the  audit  to
obtain reasonable assurance about whether the financial statements are free
of  material  misstatement.  An audit includes examining, on a test  basis,
evidence   supporting  the  amounts  and  disclosures  in   the   financial
statements.   An  audit  also includes assessing the accounting  principles
used  and  significant estimates made by management, as well as  evaluating
the  overall financial statement presentation.  We believe that our  audits
provide a reasonable basis for our opinion.

In  our opinion, the financial statements referred to above present fairly,
in all material respects, the net assets available for plan benefits of the
Plan  at  December  31, 1998 and 1997, and the changes in  its  net  assets
available  for  plan benefits for the years then ended, in conformity  with
generally accepted accounting principles.

                THE BP AMERICA SAVINGS AND INVESTMENT PLAN

                       Notes to Financial Statements
                             December 30, 1998

NOTE A - DESCRIPTION OF PLAN

The  following description of The BP America Savings and Investment  (the  Plan)
provides  only  general  information. Participants  should  refer  to  the  Plan
document for a more complete description of the Plan's provisions.

General  Provisions. BP Amoco p.l.c. was created on December  31,  1998  by  the
merger  of  Amoco  Corporation and The British Petroleum  Company  p.l.c.  (BP).
Following  this  merger, BP was renamed BP Amoco p.l.c. (BP Amoco).  BP  America
Inc.  (the  Company)  is  an  indirect wholly owned subsidiary  of  The  British
Petroleum Company p.l.c. (BP). The Plan became effective July 1, 1952.

The  Plan is a defined contribution plan, which is subject to and complies  with
the  Employee  Retirement Income Security Act of 1974, as amended (ERISA).  Plan
assets  are  held in a trust under the terms and provisions of the Savings  Plan
Master  Trust  Agreement  between the Company and  Bankers  Trust  Company  (the
Trustee).  The Company is the Plan sponsor and an officer of the Company  serves
as  Plan  Administrator. Metropolitan Life Insurance Company is the Plan record-
keeper. Effective February 1,1999, Fidelity Management Trust Company will become
the Plan's trustee and Fidelity Investments Institutional Services Company, Inc.
will become the Plan's record-keeper.

Effective August 10, 1998, in accordance with the Agreement for the Purchase and
Sale of Lima Oil Refinery between a subsidiary of the Company and Clark Refining
and  Marketing  Inc.,  (Clark), dated July 1, 1998,  the  accounts  and  related
liabilities  of those participants whose employment transferred to  Clark  as  a
result of the sale (excluding certain employees and participants) were spun  off
from  the  Plan  and transferred to the Clark Retirement Savings Plan  (the  New
Plan).   In   conjunction   with   this  spin-off,  approximately   $29,383,000,
representing  the  value of the accounts of those employees transferred  to  the
buyer group, was transferred during 1998 to the trustee of the New Plan.

The  Company  may amend or terminate the Plan at any time.  Upon any termination
of  the Plan, the participating  employees are 100 percent vested in both  their
own and the Company's matching contributions included in the employees' accounts
at the time of termination.

Eligibility.   Employees  in participating collective  bargaining  units  of  an
affiliated  company  are eligible to participate in the Plan.  Employees  become
eligible  to participate after six months of continuous service. Fee-for-service
workers and independent contractors are ineligible to participate in the Plan.

                THE BP AMERICA SAVINGS AND INVESTMENT PLAN

                       Notes to Financial Statements
                             December 30, 1998

NOTE A - DESCRIPTION OF PLAN (continued)

Contributions.  Participants may contribute to the Plan on a before-tax basis or
an  after-tax  basis  up  to  16% of base pay, subject  to  legal  restrictions.
Participants may elect any of the following investment funds:  (i) BP ADS  Fund,
(ii)  Vanguard Windsor Fund,  (iii) Vanguard Growth and Income Fund,  and   (iv)
Income Fund.  Participant contributions are remitted semi-monthly to the Trustee
and  are  credited to the participant's account.  Participants  may  change  the
percentage  they contribute and the investment direction of their  contributions
throughout the year.

The  Company  contributes  quarterly  to  the  Plan  an  amount  equal  to  each
participant's contribution up to 6% of base pay. Company contributions are  made
in investments which follow the participant investment direction.

Forfeitures of employer contributions by participants who withdrew from the Plan
before  vesting  amounted  to $1,021 in 1998 and  $0  in  1997.  The  Plan  uses
forfeitures to pay certain administrative expenses and to reduce future  Company
contributions.

Investment  Transfers.   Participants may elect to sell  any  portion  of  their
investment  fund(s)  and  reinvest the proceeds in one  or  more  of  the  other
available  investment  alternatives. Investment transfers  are  limited  to  one
transfer for every three month period.

Vesting.   For  employees electing to participate in the Plan,  vesting  in  the
Company  contributions occurs after the earlier of 4 years of Plan participation
or  5  years  of continuous employment with the Company. Employees automatically
are  fully vested at death, at age 65, if declared mentally incompetent,  or  if
permanently  and  totally  disabled. Certain  collective  bargaining  agreements
provide  for  immediate vesting when a participant's employment is involuntarily
terminated  as  a  result of the sale or other disposition of  a  subsidiary  or
division on or after February 1, 1996. Employees are always completely vested in
their own contributions and all earnings pertaining to their account.

Loans.  Loans of up to one-half of the vested account balance (but not more than
$50,000  reduced by the highest outstanding loan balance of the prior 12 months)
may  be  made from the Plan.  Repayment may not exceed 60 months.  The  interest
rate on an individual participant's Plan loan remains fixed over the life of the
loan.  The  interest rate is the prime rate in effect on the 15th of  the  month
immediately preceding the quarter in which the loan was approved, plus 1%.

                             December 30, 1998

NOTE A - DESCRIPTION OF PLAN (concluded)

Withdrawals. Active Plan participants may generally receive, for any reason, in-
service  withdrawals of their after-tax contributions, associated earnings  and,
if  they  are  vested, all related Company contributions and  earnings  thereon.
Withdrawals  of before-tax contributions and the pre-1988 earnings thereon,  are
generally available only for participants if at least age 59 1/2, if totally and
permanently  disabled or in the case of approved financial hardship. Withdrawals
may  be received in cash or in kind, except hardship withdrawals  which can only
be paid in cash.

Retirement   and  Termination  of  Employment.   Upon  termination   of   active
participation  by  reason  of retirement, distribution  of  the  vested  account
balance  may  generally  be made at the participant's election  in  one  of  the
following forms:

     a)  immediate or postponed lump sum
     b)  purchase of an annuity from an insurance company
     c)  installment payments
     d)  partial withdrawals

For  termination  other than by retirement, participants  are  only  allowed  to
select either an immediate or postponed lump sum distribution.

NOTE B - PLAN AMENDMENTS

During  1997,  two investment funds were renamed and  the Plan  was  amended  to
clarify the calculation of matching contributions and the restoration of account
balances upon reemployment.

During  1998, the Plan eliminated the U.S. Government Bond Fund and amended  the
description of classes or groups of eligible employees.

NOTE C - ACCOUNTING POLICIES

General.  The financial statements of the Plan are prepared on the accrual basis
of  accounting  in  accordance  with generally  accepted  accounting  principles
(GAAP).

Use  of  Estimates.  The preparation of financial statements in conformity  with
GAAP  requires  the Company to make estimates and assumptions  that  affect  the
reported  amount of net assets.  Actual results could differ from the  estimates
and assumptions used.

                             December 30, 1998

NOTE C - ACCOUNTING POLICIES (concluded)

Investment  Valuation.   Investments are valued  at  quoted  market  prices,  if
available.  Investments in guaranteed investment contracts, owned by the  Master
Trust, including the Plan's share of such contracts held in the Income Fund, are
valued  at fair value because the contracts are not fully benefit responsive  as
there  is  a  severe  penalty  for  early  withdrawal.  Investments  in  managed
portfolios,   collateralized   mortgage  obligations,   and   other   government
obligations  held  in the Income Fund are carried at market value,  adjusted  to
reflect,  if  applicable,  amounts  that  would  become  due  or  payable  under
agreements with financial institutions should the underlying securities be  sold
prior  to  maturity.  Other investments for which no quoted  market  prices  are
available  are  valued at fair value as determined by the Bankers Trust  Company
based  on the advice of its investment consultants. Realized gains or losses  on
security transactions are determined on the trade date by the difference between
proceeds  received and average cost of the investment.  Premiums  and  discounts
are amortized over the life of the securities.

Plan  Expenses.   Administrative expenses are primarily  paid  by  the  Company;
investment processing fees are paid by affected participants from Plan assets.

                THE BP AMERICA SAVINGS AND INVESTMENT PLAN

                       Notes to Financial Statements
                             December 30, 1998

NOTE E - INCOME TAX STATUS

The  Internal Revenue Service has determined and informed the Company by  letter
dated  February 5, 1996, that the  Plan qualifies under Section  401(a)  of  the
Internal Revenue Code (the Code) and that the Trust is tax exempt under  Section
501(a) of the Code.  The Plan has been amended since receiving the determination
letter.  However, the Plan administrator and the Company's tax  counsel  believe
the  Plan continues to meet the applicable tax qualification requirements of the
Code.

NOTE F - INCOME FUND

The  Income Fund (formerly the Fixed Income Fund) invests primarily with managed
portfolio companies and  insurance companies in contracts where the repayment of
principal and payment of interest at a fixed rate for a fixed period of time are
backed  by  the  financial  strength of such financial  institutions.  The  Plan
intends  to hold these contracts to maturity. The Income Fund does not  purchase
on  margin  or  leverage  investments, which  limits  potential  losses  to  the
investments  themselves. The Income Fund also invests in U.S.  Government-backed
agency obligations or in contracts backed by such obligations.

The  managed  portfolio companies invest in mortgage-backed  obligations,  money
market instruments, corporate bonds, assets-backed securities, private placement
bonds,  fixed  income securities, non-convertible preferred stock,  futures  and
options,  government  notes  and bonds,  and foreign  corporate  and  government
bonds. The investment contracts contain investment-type concentration guidelines
and quality guidelines based on the market value of the portfolio.

The  Plan's relative interest in the contracts with managed portfolio  companies
and  insurance  companies represents the maximum potential  credit  losses  from
concentrations of credit risk associated with its investment in the Income Fund.

In  order  to  assure the realization of the carrying amount  of  collateralized
mortgage  obligations,  should the securities be sold  prior  to  maturity,  the
Income Fund enters into agreements with financial institutions, under the  terms
of  which,  in certain situations, upon the sale of the securities,  the  Income
Fund  would  receive the carrying amount of the securities with  any  difference
between such carrying amount and the sales proceeds charged or credited  to  the
account of the financial institution.  At December 30, 1998 and 1997, the Plan's
relative interest in amounts that would be received by the Income Fund from such
financial institutions amounted to $950,000 and $3,830,000, respectively.

                             December 30, 1998

NOTE F - INCOME FUND (continued)

Certain  other employee benefit plans of the Company participate in  the  Income
Fund.   Each plan's relative interest in the Income Fund and the related  income
and administrative expense is determined on a basis proportionate to each plan's
past  contributions  adjusted  to  reflect distributions,  transfers  and  prior
investment  earnings.  The Plan's share of the Income Fund was 4.5% at  December
30, 1998 and 5.7% at December 30, 1997.

Participants' accounts earn a blended rate, or weighted average, of all  of  the
investments  held  in  the Income Fund.  Identified below are  the  Income  Fund
investments as of December 30, 1998 and 1997:

                THE BP AMERICA SAVINGS AND INVESTMENT PLAN

                       Notes to Financial Statements
                             December 30, 1998

NOTE H - YEAR 2000 (UNAUDITED)

The Year 2000 issue, which stems from computer programs written using two digits
rather  than  four  to  define the applicable year, could result  in  processing
faults on the change of the century, producing a wide range of consequences.

The  Plan  relies on some Company systems for certain aspects of its  operation.
The  Company  has  conducted a risk-based review of  its  computer  systems  and
computer-controlled  processes to identify those which  could  be  affected  and
developed  an implementation plan to test and remediate the faults. The  Company
is  replacing  or  repairing the affected systems, in close  collaboration  with
system  suppliers.  All business-critical work is due to be completed  by  June,
1999.

The  Company and the Plan are also exposed, to an unquantifiable degree, to  the
failure of third party service providers to deal with their Year 2000 exposures;
the Company is taking all practical steps to mitigate the effect.
