Answer 2

I really don't know of any, that I can verify. Quite a few years back, I owned a Packard Automobile, and it was nearly new with only 12K miles on it, at that time Sohio (Standard Oil) came out with a synthetic oil called "Premex" or something close, and it was quaranteed to work well in any car, and prevent wear.
I went for this product as I was very fond of this car and wanted to give it the best possible care.
I used it for over two years, and never had to add between changes. I then made a trip from nothern Ohio to the upper peninsula of Michigan, and while there decided to get the oil changed as it was slightly overdue, well, they did not have the Premex product there so I accpeted the best quality oil they had, and from that day on, my car burned oil like you woudn't believe, I used 3-1/2 quarts on the way home, 550 miles, and it never did stop, even after going back to the Premex.
I have not fallen for any claims of synthetic oils since.

Answer 3

you don't have to change it as often. It also doesn't leave a lot of residue in your engine, infact, it tends to clean it out over time. Because of this, If you have leaks in your oil pan and other engine gaskets, you will expose them with synthetic. You will get oil leaks.
Don't use synthetic oil on an older engine because of this reason.

You can change the oil filter only and add a small amount of oil to level off the dip stick at around 3000+ miles. You can go another 3-4000 miles for your next complete oil change.
With conventional oil, you change oil & filter every 3000 miles.

Synthetic oil is also said to give a small boost of horsepower to your engine whereas conventional oil does not. It reduces friction more than conventional because of its suspension properties.It carries particles with it instead of depositing them on the inner surfaces /walls of your engine.
Synthetic is also more expensive, but worth it down the line.

Answer 4

WARNING DO NOT USE SYNTHETIC OIL IN A MOTORCYCLE. They are the best thing for cars since sliced bread but are worse for motorcycles than metal shavings. If you have the slightest clutch weakness in your bike, synthetics will amplify them and make the clutch slip like a broken torque converter.

Cars on the other hand, benefit greatly from synthetics thanks to energy conserving molecules that slip easier and don't break down under extreme heat. They can last in your car engine for much much longer. I have been running 10,000 mile oil changes on my Chrysler 300M for 2 years now because of Mobil1 SuperSyn.

Answer 5

with full synthetic oils not the blends. they are made solely from man made chemicals in a lab. not like that of conventional oils that are refined from crude oil out of the ground that may still have some degree of dirt in it. and its not as pure. from what i understand,,

hope this helps

Answer 6

Stabiltiy of the oil between oil changes. Higher resistance to breakdown from heat.

Answer 7

Less money in your pocket to slow you down.
