Ravenol Running In Oil SAE30 5 Litre

RAVENOL Running-In / Break-In oil is a non friction modified, low detergent & dispersant SAE30 engine oil, designed for the critical running in period for both new and re-built 4-stroke engines. The high zinc formulation protects the valve train including camshafts, followers, rockers and pushrods during the running-in period. It allows the piston rings to bed in correctly with the cylinder walls and prevents glazing of the bores.

Note this oil should only be used for a maximum of 500 miles or so after which both oil and filter should be replaced.

Not suitable for vehicles with catalytic converters

OUR TIP:
This oil has been developed for use in engines that are run-in on the road. Ask your engine builder which rev range brings the optimal levels of torque, and try to remain within that range. Driving at low engine speeds can be as detrimental to the successful running-in of your new engine as revving it too highly! Try to avoid long sections of motorway or heavy town traffic, instead head off to the mountains and drive some of the beautiful twisty roads we have in this country, frequently changing gear and keeping the engine "on the cam". 
NB. Your engine will use oil during the running-in period, so check the oil level frequently - at least every 80 miles or so - it is not unusual to use an extra litre before the engine is run-in, so make sure you order enough!
Once your engine stops using oil, usually between 3-500 miles, it is run-in, and it is time to change to the RAVENOL oil recommended for your car.
