the oil will not break down as quickly but it will still break down and the filter only can catch so much before it's 'full' and all the dirty oil is just passing through the bypass valve. personally, after a lot of my own research, i would recommend changing conventional oil every 3k miles and synthetic every ~6k.
People with economics degrees will typically make around $70,000 to $115,000 at their peak. If you have a finance degree, then you can expect around $65,000 to $170,000. At the same time, this entirely depends on your position. For example, some less motivated finance degree holders work for years as bank tellers.
The amount earned from a finance career varies based on which type of position is pursued. For example, a financial analyst with a finance major is likely to earn an average salary of nearly $77,000, while a real estate appraiser with the same degree is likely to earn around $49,000. Accountants and auditors earn a median yearly salary of $63,500, while budget analysts earn $69,000.
