Five-gallon pail of Royal Purple Duralec Ultra SAE 10W-30, part number 85456. Duralec Ultra is built around Royal Purple's proprietary Synerlec additive technology, which the manufacturer rates at up to four times the film strength of leading competitors.
The 10W-30 grade of Duralec Ultra carries an HTHS of 3.3 cP at 150 C and a pour point of -48 C (-54 F), so it flows readily on cold starts while still holding film thickness at operating temperature. Pail quantity suits shops and owners servicing several machines.
Key Features
- Synerlec additive technology for high film strength and lubricity
- Wear protection rated by Royal Purple at up to 33 percent better than CK-4 requirements
- Oil life rated at up to 40 percent better than CK-4 requirements
- Improved cold-flow behavior and start-up protection
- Reduced oil consumption and advanced synthetic solvency to keep internals clean
- Suited to older-generation, high-output diesel engines as well as current on/off-highway equipment
