That's easy synthetic oil. Ill tell you why it sounds better
No.
No contest. -Synthetic oil is way better, but can you afford it. -I think using regular oil and changing every 3,000 is better.
If your engine leaks oil, no you should not use synthetic oil because it will clean sludge and can make the leak worse. If your engine does not leak oil, I would highly recomend using synthetic oil(Pennzoil Ultra 10W30 from Walmart is a good and pretty cheap choice). As long as your engine does not leak oil using synthetic oil is a great choice regardless of how old it is.
yes
3000 miles if using regular oil, 6000 if using synthetic. I use synthetic for my RSX-S, but regular would do for a base model.
You need to think about what you are going to be using it for. Also, whether the oil is synthetic or not. Buying good oil is very important. Synthetic oil is not always good.
Using 5W30 synthetic oil in a submersible sump pump is generally not recommended. Most sump pumps are designed to operate with specific lubricants, typically a lighter oil or grease specifically formulated for electric motors. Using the wrong type of oil can affect the pump's performance and longevity. Always consult the manufacturer's guidelines for the appropriate lubricant to use.
You can mix part synthetic oil with full synthetic oil.
No, I would not recommend using synthetic in an engine this old. Use a good 10w40 conventional oil.
