S63 guide

• Engine oil every 5,000 miles or once a year, and after track or race events. We recommend 5W-40 and a genuine filter. It takes 8.5 litres; buy 10 so you have a top-up.
• Gearbox oil every 50,000 miles or 5 years, BMW or Motul DCT fluid.
• Diff oil every 10,000 miles or two years, 75W-140, 1.1 litres.
• Spark plugs every 15,000 miles or two years, gapped at 0.022 inch unless on a hybrid turbo or methanol setup.
• Coil packs every 25,000 miles or 3 years.
• Panel filters every 10,000 miles or two years. Avoid oiled filters, which contaminate the MAF sensors and cause misfires, and check the MAF sensors whenever you change a filter.
• Injectors aren't a service item, and fitting them isn't a DIY job: it needs a removal tool and coding, on a 200 bar fuel system.

• Start the car, idle for 20 to 30 seconds, then drive gently until the oil reaches about 80 C. Oil pressure stays higher and everything warms faster than when idling.
• Full throttle at low rpm stresses the rods and clutch. Below 3,000 rpm, drop a gear first. We go to full power from 4,000 rpm.
• Never rev hard when parked and cold, and never hold it on the limiter when parked.
• When driving hard, use 3 bars on the gearbox setting (D3 or S3). Lower modes put less pressure on the clutch and it wears faster.
• On stock turbos, short shift at 6,500 rpm for the best speed and power, and don't go past 7,000.
• Always use 99 RON fuel. Most stations' premium fuel is only 97 RON.
• Brakes: OEM discs and genuine pads for the road. For track use keep OEM at the rear and fit Pagid RS29 at the front.
• Tyres: we use Michelin 4S, 265 front and 305 rear. Cold pressures of 34 psi front and 30 psi rear help traction.

• Engine oil every 5,000 miles or once a year, and after track or race events. We recommend 5W-40 and a genuine filter. It takes 10 litres; buy 11 so you have a top-up.
• Gearbox oil every 50,000 miles. BMW says it's lifetime (100,000 miles).
• Diff oil every 30,000 miles. BMW recommends 90,000.
• Spark plugs every 15,000 miles or two years.
• Coil packs every 25,000 miles or three years.
• Air filters every 10,000 miles or two years.

No. It's there to warm the catalytic converters quickly for emissions. It's arguably bad for engine health, and on a decatted car only the noise is left.

Coolant and oil temperatures are controlled by the engine ECUs. Sport Plus, for example, asks for a lower temperature and gets it quickly.

The engine wasn't designed for oil that thick, and these engines already have a reputation for bearing wear. We wouldn't use it unless the engine was built with its specs checked to suit.

A remap stays detectable by BMW even after flashing back, so only tune your car if you aren't keeping the warranty.

Yes. They're written in-house by Tommy, you decide how aggressive the tune is, and you can see the datalogging and adjustments while you visit.
