Off-Season Storage Checklist for Track & Performance Cars

A track car can spend more time parked than running. Before a long break, prepare the engine, fuel system, battery and tires together. This checklist helps you plan that work without assuming that every performance engine needs the same procedure.

Quick answer: choose a dry storage environment, follow the manufacturer's fluid and fuel instructions, ask your engine builder whether internal fogging protection is appropriate, and document how the car must be returned to service.

1. Decide what kind of storage you are preparing for

Tell your technician how long the car is likely to sit, where it will be kept, which fuel it uses and whether the engine has been modified. A race engine in an unconditioned trailer can need a different plan from a standard road car in a climate-controlled garage.

Use the vehicle manufacturer's service information and the engine builder's instructions as the starting point. A general checklist cannot establish compatibility for every turbocharger, intake system, engine coating or fuel system.

2. Prepare the car and storage space

• Clean the vehicle and let it dry completely before covering it.
• Choose a dry, ventilated location and a cover appropriate to that environment.
• Check for leaks and address existing mechanical problems before layup.
• Record the storage date, fuel, maintenance performed and planned restart checks.

3. Address oil, coolant and fuel separately

Check the engine oil's condition and maintenance interval; arrange an oil and filter change when appropriate. Check coolant level and the specified mixture for your climate.

Follow the fuel-system manufacturer's or builder's storage procedure, particularly for ethanol blends and methanol race fuels. Use a compatible fuel stabilizer only as directed by its label. Fogging oil and fuel stabilizer perform different jobs; one does not replace the other.

Browse engine oils or ask EDO about a storage preparation plan.

4. Consider internal engine protection

Moisture can contribute to corrosion on exposed internal metal surfaces during inactivity. FOGGIT FG-101 engine fogging oil is marketed for high-performance and racing engines during downtime and storage. It is intended to leave a protective film on treated surfaces.

Before applying it, confirm that fogging is appropriate for your engine and establish the method with the builder. Follow the current product label for application quantity and technique. Intake access, fuel and ignition isolation, and restart steps are engine-specific; do not spray into an arbitrary intake location or use an unverified universal procedure.

5. Prepare the battery and tires

Follow the battery manufacturer's storage instructions. If a maintainer is appropriate, select one compatible with the battery chemistry and electrical system. Check tire pressure and use the tire manufacturer's guidance for extended parking and flat-spot prevention.

Keep a clear checklist of any disconnected components or temporary covers so they are addressed before the next start.

6. Make a return-to-service checklist

• Inspect for leaks, pests, damaged wiring and deterioration.
• Remove any temporary intake or exhaust covers before starting.
• Check fluids, battery condition, tires and brakes.
• Follow the builder's procedure for restoring fuel and ignition and preparing oil pressure.
• Stop and investigate persistent misfires, abnormal noises or warning lights.

Fogging protection does not repair existing corrosion or guarantee a fault-free restart. If the engine's storage history is unknown or corrosion is suspected, have it inspected before running it.
