I am tired of hearing about the 3,000 mile oil change as being unnecessary and wasteful.
There are numerous people saying that 3,000 mile oil changes are not needed as oil lasts 5,000 to 20,000 miles depending on the oil used. While this may be true from an additive and shear stability viewpoint it is not the only matter. Some cars are not driven 3,000 miles in 10 years.
TIME is an independent variable. MOST manufacturers state the oils must be changed at least yearly OR within some mileage criteria. Again, the “OR YEARLY” part is equally important.
I refer to the diurnal heating and cooling cycle that introduces moisture into your engine. This results in corrosion as the water builds up. In arid climates it is less of a problem but in sunny Florida where moisture abounds it is a severe problem, especially for sports cars that sit around with a lack of use. Also, the northern cold winter cycle is particularly hard on mineral based oils that may form gels. This is why I advocate changing oils in the spring of every year for those cars that do not meet the mileage requirement.
