Review: Great primary oil. - Good stuff. Runs quiet. Dissipates heat. Compatible with HD big twins. Good value. Review: Smooth.. - This stuff is legit. I recently had a clutch cable break. I was running formula+ in the primary. I installed this when I installed the new cable as the clutch was slipping prior. Shifting into first is smooth, and primary noise is minimal at idle. So far it’s doing great. Maybe 200ish miles. ## Features - Cools and quiets - Designed for heavy duty high performance situations - Meets or exceeds all OEM requirements ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005MZD0NM | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #33,832 in Automotive ( See Top 100 in Automotive ) #457 in Motor Oils | | Brand | Lucas Oil | | Brand Name | Lucas Oil | | Compatible with Vehicle Type | Various | | Container Type | Bottle | | Customer Reviews | 4.8 out of 5 stars 1,030 Reviews | | Global Trade Identification Number | 00049807107901 | | Included Components | 1x 1 Quart bottle | | Item Type Name | chaincase oil | | Item Weight | 2 pounds | | Liquid Volume | 1 quarts | | Manufacturer | Lucas Oil | | Manufacturer Part Number | 10790 | | Model Number | 10790 | | Number of Packs | 1 | | Package Information | Bottle | | SAE J300 Viscosity Grade | 10W | | Size | 1 Quart | | UPC | 049807407902 049807107901 | | Unit Count | 128 Fluid Ounces | | Vehicle Service Type | Various | ## Product Details - **Brand:** Lucas Oil - **Liquid Volume:** 1 Quarts - **Package Information:** Bottle - **SAE J300 Viscosity Grade:** 10W - **Vehicle Service Type:** Various ## Images ![10790 Primary Chaincase Oil - 1 Quart - Image 1](https://m.media-amazon.com/images/I/51b96r6izAL.jpg) ![10790 Primary Chaincase Oil - 1 Quart - Image 2](https://m.media-amazon.com/images/I/61Wq5bKHSxL.jpg) ## Available Options This product comes in different **Number Of Items** options. ## Questions & Answers **Q: This is a lubricant right?
