Calcium compounds are widely used. There are vast deposits of limestone (calcium carbonate) used directly as a building stone and indirectly for cement. When limestone is heated in kilns it gives off carbon dioxide gas leaving behind quicklime (calcium oxide).
How to Change Transmission Fluid. Transmission fluid needs to be changed from time to time in order to extend the life of the transmission, usually every 30,000â60,000 miles (48,000â97,000 km) (sometimes more â check your owner's manual for service intervals).
My owners manual states that I should change my transmission fluid and filter at 100,000 miles for a vehicle that experiences normal driving. My question is this- should I follow the owners manual on this or change out the fluid and filter at 75,000 miles?
