It is suspicious right. Just note the following few points:
- As long as it is new engine oil, it is safe to drive another 3k - 5k or 3 - 6 months
- You can flush the engine oil next time you change the oil
- You can change the oil earlier next time, e.g. after 3 months, or 3k km
Some drivers do not change their engine oil every 6 months or 5k km. As the result, after 5 years, the engine may accumulated some dark oil and dirt, but they may be just 5% in the whole engine. Therefore, the new oil will look 5% darker, but it is very safe with that.
If you want it even cleaner, look for work shop with engine flusher. This is a piece of equipment which connect 1 host in, and 1 host out to flush the engine. I believe it is $80. While the engine flush oil is < $30, and after 1 flush it is not fully clean up the dirt and give you the color you expect.
If you use normal oil but change it every 3 months (and drive less than 3k km), you only spend $90, and get very clean oil as well.
Advice, change 3 month normal oil ($15), next 3 month normal oil ($15), next 3 month synthetic oil ($35). Total $65. Don't spend money to buy flush engine oil, or flush engine with special equipment.
Reason: engine oil will be clean enough after 3 change, and won't damage the engine
