CRC Aerostart a starting fluid which is uses a highly effective formula to help start neglected engines that need an extra bit of encouragement. CRC Aerostart is a balanced formulation which combines volatile solvents, upper cylinder lubricants and corrosion inhibitors, each designed to play a vital role in engines which have been sitting for extended periods. The handy 150g can is a perfect size to keep in the glove box or storage compartment of any cars, boats, trucks, buses, tractors, chainsaws or any petrol or diesel powered engines. Simply have someone spray it into your car's air intake whilst cranking the start motor and watch your car rumble into life! Older vehicles and project cars with fuel system issues needing attention can often be given an extra bit of motivation with Aerostart. Although we recommend replacing fuel system components when they've past their use by, for occasional vehicles or just to move them around the workshop or garage, Aerostart is great for getting those tired motors running. Starting fluid can also be necessary for perfectly healthy vehicles that have been sitting for some time. Fuel systems often run dry or will form air bubbles meaning that the fuel system can't build pressure and operate correctly. Aerostart will effectively allow the engine to run without its normal fuel supply, but once running will eventually build pressure and draw fuel from its own tank. Starting spray is also great to keep in the car when you're hitting the slopes in the snow season as cold conditions can also make it harder for engines to start, the same can be said for excessively humid conditions in the tropics.
