Hubert Glass Oil Synthetic 0W-20 Motor Oil, 4 x 5-Quart Case #G020S-5Q
The Hubert Glass Oil #G020S-5Q is Glass Full Synthetic 0W-20 motor oil in a 4 x 5-quart case — 20 quarts (5 gallons) of API SP / ILSAC GF-6 synthetic for gasoline engines whose owner's manual calls for SAE 0W-20. Hubert Glass Oil Co. blends it in Jacksonville, Texas, and the Glass Full Synthetic line is their top-tier engine oil: four grades, one data sheet, rated API SP / ILSAC GF-6 across the board.
On the data sheet's own numbers for 0W-20: 44.26 cSt at 40 °C and 8.6 cSt at 100 °C, a 176 viscosity index — the highest in the line — a flash point above 200 °C (COC) and a cold-crank of 4,230 cP at -35 °C. That VI and CCS pair is the 0W-20 story: maximum cold-start flow for the modern engines that specify it. The sheet prints no pour point for this grade, so the page does not invent one.

- Containers are not designed to hold pressure — never pressurize, cut, weld or heat them
- Bonding and grounding may be needed during handling (static)
- Used oil goes to a collection service, not the trash
Questions Shops Ask
Which grade does my vehicle or fleet need?
The oil cap and owner's manual are the authority. This case is 0W-20 — for engines specified for it. If your cap calls for 5W-20, 5W-30 or 10W-30, we stock those grades of the same line (G520S-5Q, G530S-5Q, G1030S-5Q). Never substitute grades unless the engine documentation allows it.
Is this oil licensed to API SP / ILSAC GF-6?
Per the manufacturer's data sheet, the Glass Full Synthetic line is rated API SP / ILSAC GF-6 across all four grades (0W-20, 5W-20, 5W-30, 10W-30). The sheet lists no OEM-specific approvals — no dexos, Ford or Chrysler specs — so if your engine requires a specific OEM approval, check that requirement before ordering.
Why 0W-20?
It is the thinnest grade of the line with the strongest viscosity index — 176 against 159 for the 5W grades — and a cold-crank of 4,230 cP at -35 °C. Engines designed for 0W-20 rely on that flow at cold start; if your engine calls for it, do not step up to a heavier grade without checking the OEM guidance.
Is there a minimum order?
Yes — there is a minimum for Glass Oil orders, stated in the highlighted notice on this page. If the Glass Oil items in your cart fall short at checkout, we cannot fulfill the order; we will contact you and refund you in full. Questions about combining Glass Oil items to reach it? Call (817) 865-3707.
How should I handle and store it?
Per the SDS (9719 Rev 4, dated 2025-12-30): it is not regulated as a hazardous material for transport, carries NFPA ratings of Health 0 / Flammability 1 / Reactivity 0, and is harmful to aquatic life — avoid release to the environment. The jugs are not pressure containers: never pressurize, cut, weld or heat them, and watch for static during handling. Route used oil to a collection service.

Fitment & Handling
Confirm the SAE grade your engine specifies before filling — the oil cap and owner's manual are the authority, and the data sheet's own guidance is to confirm the product against the OEM recommendation for the equipment's operating conditions. This line carries API SP / ILSAC GF-6; the data sheet claims no OEM-specific approvals. Do not substitute grades unless the engine documentation allows it. For the cold-start grade your engine specifies, this is the 0W-20 case of the Glass Full Synthetic line.
