Масло на одну гонку, для конкретных целей и двигателей. Для большинства моторов не подходит, не только по вязкости,
но и по содержанию цинка-фосфора.
Вот "типичный" представитель линейки W-10 и его рекомендации:
- Used by many NHRA Pro Stock teams for dyno testing
- Much longer drain intervals than competing brands at similar viscosity
- Also used in Jr. Dragster engines
- Popular in IHRA Pro Stock, Top Sportsman (normally aspirated), ADRL Extreme Pro Stock and NHRA Competition Eliminator
ABOUT RED LINE MOTOR OIL FOR RACING
- Reformulated for improved frictional properties
- Special detergents for improved lubricity and less detonation
- Polyol ester base stocks provide more stability and film strength when exposed to excess fuel dilution
- Each of these products has no less than 2200ppm of zinc and phosphorus for antiwear
- Each race oil product is a multi-grade, offering 2-4% more power than oil of a similar viscosity - 20WT is a 5W20, 30WT is a 10W30, 40WT is a 15W40, 50WT is a 15W50
- Improved protection at startup, lower oil temp, cleanliness
- Remember to change these oils more frequently than regular motor oils

*************************************
Но этой вязкостью дело не ограничивается.
Имеется w-5 и w-2. Есть желающие залить?

На горячую вязкость
3 сс!
