A starting point citing this series by name and code. Replace the bracketed terms with your contract's actual scope before use.
The [affected portion] of the Contract Price shall be adjusted using US PPI — Petroleum Lubricating Oil and Grease Manufacturing (BLS series PCU324191324191), published by BLS. Base Period: the index value published for September 2026 (or the month of contract signing, if different) is the Base Value. Adjustment: at each Adjustment Date, the Current Value is the most recently published three-month average of the index (the Averaging Window). The Escalation Factor equals Current Value divided by Base Value. Cap: the Escalation Factor applied under this clause shall not exceed 1.10 or fall below 0.90 (a 10% cap and floor) in any single Adjustment Date, regardless of the index's actual movement. [Replace bracketed terms with your contract's actual affected-portion definition and adjustment-date schedule before use. This is a drafting starting point, not legal advice.]
Use when neither contract party holds an Argus or ICIS subscription, or as a free sanity check against a subscription-based number.
Base oils have two real named benchmarks, Argus Base Oils and ICIS Base Oils-Lubes, both weekly, both subscription-only. A domestic BLS proxy exists as a free fallback, PCU324191324191 for lubricating oil and grease. There is no confirmed standalone "Argus Additives" product, despite that name circulating informally, so verify the exact report name before citing one in a contract.
Escalake tracks US PPI — Petroleum Lubricating Oil and Grease Manufacturing, applies your formula, and gives both sides a number they can confirm, no spreadsheet required.
