Is synthetic motor oil worth the price premium?

Question

It lasts 6 months compared to 3 months for regular oil.

Answer 1

  Synthetic lubricates much better it will also run cooler than normal oil. You should see a slight gain in fuel economy as well.  I also use the mobile as well.  I also think its much better for the seals. Although I wouldn't go no 10,000 miles as I've heard of other people doing. To me that's stupid just because it don't break down as easily doesn't mean it is not going to get dirty. I go 5000 between changes.

Answer 2

Synthetic oil is much better for your engine.  I exclusively use Mobil1 since it contains no crude based oil.  Yes, it is more expensive but you will save yourself the money in the long run by possibly not have costly engine damage down the road.  

However, oil is only as good as often as you change it.  You still need to change synthetic just as you would conventional oil based on your vehicles maintenance schedule, especially if its still under warranty.  Once its out of warranty, you can change it whenever you want.  

Answer 3

No, it's a waste of money. Not to mention if you use it on an older engine you will create leaks and start burning oil past the rings.

If one wants to use synthetic then one must use it from the start when the engine is new so it's broke in on it. Otherwise you're creating problems for yourself.

Don't waste your money, just stick with a good brand of regular oil.

Answer 4

It's a very good alternative because of the the improved additive package. The detergents are more aggressive, the extreme pressure additives are better. It resists friction thus runs cooler. It pours at lower temperatures than the same viscosity grade of conventianal oil. It evaporates at higher temperatures. It's flash to fire point is higher than conventional oil. You may realize a bit of mileage improvement because it is more slippery than conventianal oil. It resists sludge and varnish far better.

The Viper and Corvette ZO6 has Mobil1 in the crankcase from the manufacturer before the dealer sees the cars.

If your motor is still under factory warranty do not under any circumstanses drive beyond the factory recommended oil change intervals regardless of the oil type. You always need to produce service records in case of any mechanical failure.

Answer 5

I don't think so - and I've had work trucks with over 200,000 on them.

Oil and filter change every 6 months or 6000 miles with a high quality conventional motor oil.

I seriously doubt I would do any better if I opted for the more expensive synthetic.
