Hubert Glass Oil Synthetic 40W Racing Motor Oil 55-Gallon Drum #G40S-D
The Hubert Glass Oil #G40S-D is Glass Synthetic 40W motor oil in a 55-gallon drum — a heavy straight racing-grade from a blender who has been making oil since 1953. Carried in the Glass price book for dirt-track, late-model and other engines spec'd to a heavy 40-weight fill.
Order it for the application, not instead of a multi-grade: straight 40W goes where the engine builder or rulebook calls for it. Questions on whether it fits your program? Call before the order ships.
Where It Works — Per the Data Sheet / Price Book
- Racing engines spec'd to a straight 40W fill

Features & Benefits
- A true racing weight, in drum quantity. One drum covers a season of maintenance for a serious program.
- Texas-blended. Made in-house in Jacksonville, Texas.
Questions Shops Ask
Is 40W the same as 10W-40?
No. Straight 40W is a single-grade racing-style oil; 10W-40 is a multi-grade for street engines. If your engine calls for 10W-40, do not substitute this — call (817) 865-3707 and we will match the right product.
Is there a minimum order?
Yes — see 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.
