Overview
The Lucas Oil Synthetic SAE 10W-40 Motor Oil, part number 10942, is a synthetic 10W-40 oil that Lucas positions for precision ET racing. Lucas says its steady viscosity is intended for that use.
The additive package reduces drag while still guarding metal surfaces, and the oil suits normal highway use. It is universal fit, so it is not tied to a named vehicle.
Key features
- Synthetic 10W-40 viscosity grade
- Lubricity agents in the additive package
- Anti-seize agents that guard metal
- Steady viscosity for precision ET racing, per Lucas
- Suited to normal highway use
Racing oil on the street
Racing oils are built to hold their viscosity steady under high heat and sustained load, which is useful on track but also changes how the oil behaves on a cold morning. A 10W-40 synthetic gives a thinner start-up flow than a heavier grade, and that matters for engines that see frequent cold starts. Before using any racing-oriented oil in a street engine, confirm the grade and category your engine calls for.
Track use generally adds heat, rpm and oil stress, so the oil may need checking more often than on the road. Look at color, level and smell after each session, and keep a log of how many events the oil has seen. Keep filters and drain plugs in good condition as well.
- Check oil level before and after each session
- Note any change in color or smell
- Keep a service log for track and street use
