Hubert Glass Oil Synthetic Blend 10W-30 CK-4 Diesel Motor Oil 55-Gallon Drum #G1030D-D
The Hubert Glass Oil #G1030D-D is Glass Syn Blend CK-4 10W-30 HD diesel engine oil in 55-gallon drum — the 10W-30 fleet grade for diesel operations that want the thinner cold-flow spread without stepping up to a full synthetic.
A 10W-30 CK-4 goes where the equipment documentation calls for it — winter service, mixed fleets, or engines spec'd below 15W-40. We confirm the spec before the order ships.
Where It Works — Per the Data Sheet / Price Book
- Diesel equipment spec'd to a 10W-30 CK-4 fill
- Winter and cold-start service where the 10W spread beats 15W-40
Features & Benefits
- The 10W-30 fleet grade. Cold-flow spread for diesel service, from the Glass heavy-duty book.
- Every format. Drum for the yard, pail and 3-gallon case for the field.
