Which is better synthetic oil or mineral oil?

Answer 1

Synthetic oils are much better. But do you need it?

This should help you choose. Synthetic oils are made from a oil such as soybean oil with an additive package. Conventional oils are from the ground with an additive package. Synthetic oils are much more expensive then conventional oil. Synthetic oils were designed for high performance cars. Some advantages of synthetetic oil is that it flows better when cold, reduces wear, prevents sludge buildup, burns slower, makes engines run cooler, makes engines produce more power, inproved fuel econemy, makes engines last longer and thins out less when hot. But they are so much more expensive then conventional oils that it may not be worth it. If you are racing, live someware cold, your car recomends it or you drive in extreme conditions, such as towing, excessive idling or frequent short trips, you do not need synthetic oil. The reasons are even if you get one more mile per gallon of gas and run 7500 miles between oil changes, it still is much cheaper to use conventional oil. You will still get 200000-300000 miles out of a good engine using the cheapest oil that you can find. Hope this helps!
