TVR servicing schedule and maintenance intervals
A consolidated servicing guide for TVR road cars, drawn from owner-club and specialist recommendations. The intervals below are typical for road use of Speed Six, AJP8 and Rover V8 powered cars (Cerbera, Chimaera, Griffith, Tuscan, Tamora and similar). Always cross-check against the manufacturer’s handbook for your specific car and engine, and treat anything brake-, fuel- or suspension-related as safety critical.
Time-based annual checks
Section titled “Time-based annual checks”These should be done every year regardless of how few miles the car has covered — TVRs are often laid up over winter and small problems (perished hoses, sticking calipers, a rusting servo) tend to appear after periods of inactivity.
- Engine oil and filter change.
- Coolant level and condition check; top up as required.
- Brake fluid renewal every two years (DOT 4 or DOT 5.1).
- All fluid levels checked.
- Tyre pressures and condition (including age and sidewall cracking).
- Visual chassis inspection for rust, particularly around outriggers and suspension mounts.
- Brake pads and discs inspected for wear and corrosion.
- All belts and hoses examined for cracking or perishing.
- Door hinges, locks and bonnet catches lubricated.
- Function check of lights, wipers, washers and other electrical systems.
- Hood operation on convertible models.
Mileage-based service intervals
Section titled “Mileage-based service intervals”Most TVR specialists work to short oil-change intervals on the multi-valve engines because the Speed Six and AJP8 are sensitive to oil condition. The schedule below is cumulative — a 12,000-mile service includes everything from the 6,000 and 3,000 services.
| Interval | Key tasks |
|---|---|
| 3,000 miles | Engine oil and filter; check oil pressure (Speed Six minimum ~3 bar hot at idle); inspect for oil leaks; coolant level and condition; brake fluid level; inspect brake servo for corrosion (especially underside); tyre pressures. |
| 6,000 miles | All of the above, plus: inspect spark plugs (replace if needed); check and adjust throttle linkages; check suspension for play/wear; grease all greasable points; inspect CV boots; check exhaust system and mountings; inspect fuel filter. |
| 12,000 miles | All of the above, plus: replace fuel filter; check valve clearances (Speed Six); renew spark plugs; check belt condition; check wheel bearings for play; check steering rack for leaks and play; check brake servo operation; inspect brake pipes for corrosion; check clutch operation and adjustment. |
| 24,000 miles | All of the above, plus: renew brake fluid (if not done within 2 years); renew coolant; check catalytic converter condition; inspect all suspension bushes; check differential oil level. |
Recommended fluids
Section titled “Recommended fluids”These are the grades most commonly used by TVR specialists. Confirm with your engine builder if the car has been modified or rebuilt to a non-standard specification.
| System | Recommended fluid | Notes |
|---|---|---|
| Engine oil | 10W-60 semi- or fully-synthetic | 15W-50 also used by some owners. Avoid thin grades such as 0W-30 — insufficient protection for high-revving TVR engines. Change every ~3,000 miles. |
| Gearbox — Rover LT77 | EP80 or EP90 | As used in Griffith/Chimaera and S-series. |
| Gearbox — BorgWarner T5 | EP80 (or manufacturer spec) | Common in later Rover V8 cars. |
| Gearbox — TVR 5-speed (Cerbera) | Check with specialist | Grade varies by build; confirm before topping up. |
| Differential | EP90 hypoid gear oil | Check level at every service. |
| Brake fluid | DOT 4 minimum; DOT 5.1 for track use | Do not use DOT 5 silicone fluid in standard systems. Renew every 2 years. |
| Coolant | Ethylene glycol antifreeze, mixed with distilled water | Renew every 2 years; tap water encourages internal corrosion. |
Caution — safety-critical work
Section titled “Caution — safety-critical work”Brake fluid renewal, brake pipe and servo inspection, suspension bush replacement and fuel system work should be carried out to the manufacturer’s torque and routing specification. If you are unsure, hand the job to a TVR specialist rather than guessing.
Spares worth carrying
Section titled “Spares worth carrying”TVRs reward a well-stocked boot. The list below covers the items most often needed at the roadside.
| Category | Item | Notes |
|---|---|---|
| Ignition | Spare coil pack | Particularly for AJP8 and Speed Six. |
| Electrical | Spare relays | Fuel pump, ignition and main beam at minimum. |
| Electrical | Assorted fuses | Match the ratings used in your fusebox. |
| Drive belts | Spare auxiliary/fan belt | Correct length for your engine. |
| Fluids | 1 L engine oil, 1 L coolant, small bottle of brake fluid | Top-up quantities only. |
| Lighting | Spare bulbs | Headlight, sidelight, indicator. |
| Get-you-home | Duct tape and cable ties | A TVR essential. |
Useful tools to keep with the car
Section titled “Useful tools to keep with the car”- Multimeter for tracing electrical faults.
- Jump leads.
- Basic metric socket set and screwdrivers (flat and Phillips).
- Pliers and wire cutters.
- Torque wrench for wheel nuts and roadside repairs.
- Jack and wheel brace appropriate for the car’s weight and ground clearance.
- Tyre pressure gauge.
- Infrared thermometer — useful for spot-checking running temperatures on cooling system, brakes and exhaust.
Compiled from TVR owner-club and specialist recommendations — always verify against the manufacturer’s handbook and your own specialist before relying on it.
