Petromin Super Ultra 7 20W-50 5L lubricates multi-valve gasoline and diesel engines. High-viscosity mineral stocks resist thermal breakdown during high-heat operation. Road dust won't compromise the protective film during standard drain intervals.
Key Features
- API SL/CF Rating: Meets lubrication requirements for older gasoline and diesel engines. Prevents metal-to-metal contact during starts; fails in modern turbo-GDI systems.
- Thermal Stability: Resists oil thinning under extreme engine operating temperatures. Maintains oil pressure during idling; degrades if engine cooling fails.
- Anti-wear Protection: Sacrificial additives coat pistons and camshafts to limit friction. Extends lifespan in high-mileage blocks; won't repair existing mechanical cracks.
- 5L Volume: Fills larger crankcases found in SUVs and light trucks. Eliminates multiple small bottles; wastes volume in small 3L city cars.
Frequently Asked Questions
Is Petromin 20W-50 good for diesel engines?
It works for light-duty diesel engines requiring API CF performance levels. The thick oil film helps seal worn piston rings in older engine blocks.
Where is Petromin engine oil manufactured?
Saudi Arabia produces this lubricant using Saudi Aramco base stocks. This origin maintains consistent chemical composition across different batches.
