Pressure first. Then the start.
The sequence is the product: oil moves before the engine does.
Build oil pressure first. Start the engine second.
No Dry Starts® is designed to activate an electrically driven oil pump before cranking. The system routes oil through the engine’s lubrication circuit and, in applicable configurations, confirms a pressure threshold before allowing startup. The goal is simple: reduce the interval between engine movement and effective oil delivery.
Step 1: You request a start.
The driver turns the key or presses start, as always.
Step 2: The system pre-primes the oil circuit.
An electric pump moves oil through the engine’s lubrication circuit before the starter turns the engine.
Step 3: Pressure is verified and the engine is permitted to start.
Subject to the final vehicle-specific safety strategy.
Traditional startup versus pre-primed startup.
Traditional startup
- Driver requests engine start
- Engine begins rotatingEngine turning
- Mechanical oil pump develops pressure during rotationEngine turning
- Oil circulation increases as engine runs
- Startup lubrication depends on residual oil and pressure rise
No Dry Starts® concept
- Driver requests engine start
- Electric pre-prime cycle beginsEngine still
- Oil pressure is built before crankingEngine still
- Pressure check can authorize startup
- Designed to reduce time spent rotating before oil delivery
Actual behavior depends on engine design, oil viscosity, installation, pump capacity, control strategy and operating conditions. The sequence is shown for explanation and is not to scale.
Designed to fit where the oil filter already lives.
Our lead prototype concept uses a compact sandwich adapter installed between the engine block and a compatible spin-on oil filter. The adapter houses or interfaces with an electric priming pump, allowing a targeted retrofit architecture without requiring an entirely redesigned engine.

Oil pressure first. Engine startup second.
The way engines start has remained largely unchanged. We are working to change what happens before they turn.
