Speed Oil-3 Oil

Specific protection for high-demand slot transmissions

The Speed Oil-3 SC-5312 from Scaleauto is a very high viscosity oil specifically formulated to lubricate transmissions in slot cars. Its composition includes anti-friction and super-sliding additives that reduce gear wear and prolong the lifespan of mechanical components.

Main features

• Viscosity: very high, ideal for transmissions with greater mechanical load.
• Content: 20 ml bottle with precision applicator.
• Anti-friction additives: reduce friction between moving metal surfaces.
• Super-sliding additives: promote smoother and more consistent power transmission.

Recommended applications

This oil is designed for lubricating transmissions in slot cars: gears, crowns, pinions, and any contact points between rotating parts that bear load. Its high viscosity makes it particularly suitable when a more resilient lubricant film is required, capable of staying in place during intense running sessions or in setups with greater play between parts.

Behaviour and performance

Unlike low viscosity oils —more suitable for axles or bearings—, Speed Oil-3 forms a denser protective layer over the gear teeth. This results in less heat generated by friction, reduced premature wear, and a more consistent power transmission over time. On track, the result is a quieter running gear with a more predictable response.

Usage recommendations

• Apply a minimal amount: a drop at the contact point is sufficient to lubricate the transmission.
• Clean any excess oil before running; leftover lubricant can migrate to the tyres or braids and affect performance.
• Renew lubrication periodically, especially after long sessions or in competition.
• For axles and bearings, consider using lower viscosity oils from the same Scaleauto range, reserving Speed Oil-3 for transmissions.

Frequently asked questions

What type of transmission is Speed Oil-3 most suitable for?

It is specifically designed for transmissions with gears —crowns, pinions, and their contact points— where a more viscous and resilient lubricant film is needed that does not easily displace under load.

Can I also use it on the bearings or axles of the car?

It is not the most recommended option. Its high viscosity may create more resistance in bearings and axles than desirable. For those applications, a low or medium viscosity oil from the Scaleauto range is preferable.

How much should be applied to each gear?

One well-placed drop at the contact point is more than sufficient. Excess application can dirty the inside of the chassis and contaminate tyres or braids.

How often should I lubricate the transmission?

It depends on usage. In recreational running, every few sessions. In competition or intensive use, it is advisable to check it more regularly, as the heat generated can degrade the oil over time.

Is it compatible with plastic transmissions?

Scaleauto does not specify material restrictions, but as a general rule in the hobby, it is recommended to apply a minimal amount and check for any reaction with the gear materials before continued use.

The Scaleauto Speed Oil-3 (SC-5312) is a high-viscosity slot car transmission lubricant featuring anti-friction and super-sliding additives. Supplied in a 20 ml bottle, it is designed to protect gears, crowns and pinions in slot cars, reducing wear and ensuring smooth power transfer during club racing or recreational use. An essential maintenance product for any slot car enthusiast looking to extend the life of their drivetrain components.
