Question

1. how do you dispose of dirty oil?
2. what is the typical life of an engine running on mobile 1.
3. what is the typical life of an engine not running on mobile 1.
4. what color is fresh clean oil? honey
5. what does an oil dip stick tell you.
6. what ar the two (2) categories of engine oil?

Explanation:

These questions are about engine oil and its related aspects, which fall under the subfield of Engineering (a subfield of Natural Science). Let's answer each:

1. Dirty oil should be disposed of by taking it to a certified recycling or disposal center (like an auto parts store or waste management facility that accepts used oil) to prevent environmental harm.
2. The typical life of an engine running on Mobil 1 (a synthetic oil) can vary, but with proper maintenance, engines using it can last 200,000 miles or more, depending on driving conditions, engine type, etc.
3. For an engine not using Mobil 1 (e.g., using conventional oil), typical engine life with good maintenance might be around 150,000 - 200,000 miles, but it's more variable due to oil quality and maintenance.
4. Fresh clean oil (especially conventional) is often amber or light brown (similar to honey, as noted). Synthetic oils can also be amber or slightly lighter.
5. An oil dipstick tells you the oil level (if it's within the safe range, like between "full" and "add" marks) and can give clues about oil condition (e.g., dirty, milky - which could indicate coolant mixing).
6. The two main categories of engine oil are conventional (mineral - based, derived from crude oil) and synthetic (man - made with more uniform molecules, better performance in extreme conditions). There's also synthetic - blend, but the two primary categories are conventional and synthetic.

Answer:

1. Take to a certified used - oil disposal center.
2. ~200,000+ miles (with good maintenance).
3. ~150,000 - 200,000 miles (with good maintenance).
4. Amber (or light brown, like honey).
5. Oil level and condition clues.
6. Conventional and Synthetic.
