NEVER PUT AVIATION ENGINE OIL IN YOUR CAR ENGINE!!
Contrary to some bad info posted here, they are not the same:

If you ever have any doubts about a product, just ask the manufacturer or an official product representative. Unsubstantiated internet posts can cause you a lot of grief if you take them for gospel.

If you're going to imply that regular automotive engine oils can be used in piston-engine aircraft, then that above quote pretty much blows your argument out of the water on the superiority (i.e. cost effectiveness) of synths over mineral.

14. Synthetic oils do not show superior performance when used in piston-powered aircraft.
The decision to use synthetic oils should be based on the expected use of the oil. Since synthetics cost at least twice as much as mineral oil-based products, there is a tendency on the part of the operator to expect them to outperform in all circumstances. In a piston engine aircraft environment, however, the favorable properties of synthetic oils are marginal. Supporters of synthetic oils have basically two main claims: one, they increase time between oil changes and second, they improve startability at extreme low temperatures. Synthetic oils will become contaminated just as quickly as mineral oil in a piston aircraft engine and synthetics do not show any appreciable difference in wear levels. OEMs do not distinguish between synthetics and mineral-based products for oil change recommendations. Also, for piston-powered aircraft, any possible low temperature benefit to a synthetic oil is irrelevant because piston aircraft started in temperatures of 20F or below must be pre-heated. With regard to extremely high-temperature operation, very few, if any, piston-powered aircraft are operated at temperatures that highlight the benefits of synthetic oils.

damn. I suppose im sort of wasting my life away.
I'll drop out of school first thing tomorrow.

I'm loving thise thread. 
I used Royal Purple a few times...$42 bucks per oil change! Then I have to buy the filter...screw that. I premix and removed the omp, so I think fuel somehow makes its way into my oil...Karack or someone else would have ot explain that....ANYWAYS switched to GTX, good **** 
WAYYYY cheaper too. I change my oil every 1,500-2,000 miles and it's still cheaper than the usual 3,000 mile Royal Purple oil change.

Advantages
The industry recognizes the following benefits for synthetic motor oils:
* Improved viscosity at low temperatures. Mineral oils tend to include wax impurities which coagulate at lower temperatures. A typical 10W-30 oil remains liquid at -50 °C (-58 °F)
* Better high temperature performance. Synthetic oils have few low molecular weight hydrocarbons which evaporate at high temperatures.
* Higher purity
* Decreased oil consumption
* Reduced friction and engine wear
* Improved fuel consumption through better engine lubrication
* Resistance to oil sludge problems
* Crude oil doesn't have to be used for the production of the lubricants
* Some synthetic motor oil producers offer extended intervals between oil changes (extended drain intervals)
* Reduction of environmental impact (due to lower oil consumption)
Disadvantages
The primary disadvantage of synthetic oils is that they cost significantly more than mineral oils. Some manufacturers of synthetic oils, such as Amsoil and Mobil1, however offer extended drain intervals which allows for running the oil by over 7 times the length of conventional petroleum oils. This extended drain interval actually causes synthetics to be more cost effective over the course of 2 to 3 oil changes. However, with the recent rise in the price of petroleum the gap between the cost of a typical quart of petroleum motor oil and the typical quart of synthetic is almost negligible.
Synthetic oils can cause problems with older seals which are prone to leakage. As long as the vehicle or equipment in question is in sound mechanical condition then using synthetic oils should not be an issue.

I live in Hawaii, where the climate is relatively mild.
This offers no advantage to me.
* Better high temperature performance. Synthetic oils have few low molecular weight hydrocarbons which evaporate at high temperatures.
My question is...is this a SIGNIFICANT advantage?
* Higher purity
* Decreased oil consumption
It is widely known that synths consists of smaller molecules.
Motors running originally on mineral oil and then switched over to synths will see increased consumption and increased tendency for oil leaks.
* Reduced friction and engine wear
* Improved fuel consumption through better engine lubrication
* Resistance to oil sludge problems
* Crude oil doesn't have to be used for the production of the lubricants
* Some synthetic motor oil producers offer extended intervals between oil changes (extended drain intervals)

The problem with Wikipedia is that it's a collection of "knowledge" by individuals.
It's supposed to be self-policing, but I would never label them as being the end-all authority on ANY subject.
The point about reduced consumption is WRONG.

****** lab rats....
you know the people were paid so they have to make some results. lab tests are the most bogus BS tests when it comes to real world conditions ever.
like i said, there may be some minor benefits but feeling a difference in power, smoother idle and noticing these things is all in your heads! it's like putting a K+N filter in your car, that 2HP is hardly noticable but everyone feels the difference - of course we want to feel the difference.. we just spent $60 on a damn air filter!

If it is true that they give better fuel consumption, maybe it's only by .0001%. BUT, that allows it to go on the bottle to sell.

the whole idea behind synthetic oil is that it doesnt break down as fast as conventional oils. it takes the best parts of mineral, vegetable, and animal oils and combines them.
normal oil needs to be changed because the molecular structure of the oil gets pounded from cycling through the motor, and the oils vicosity is lost, aswell as its ability to lubricate and seal.
normal oil needs to be changed every 3000 miles. syntheic oil only needs to be chnged every 10 or 15000 miles.
the catch is, just becuase your new oils molecular structure doesnt break down doesnt mean the engines combustion cycle isnt going to contaminate the engine with carbon. the filter must stiill be changed every 3000 miles, but you can leave the oil in.
synthetic oil also cleans the engine much, much, much more better than mineral oil
it should save you money in the long run...
15000 miles = 5 conventional oil changes. lets say 25 bucks per oil change (20 for oil, 5 for filter) thats 125 bucks.
lets say the synthetic is 3 times more at 15 bucks a litre, so that 60 bucks lasts you 15000 miles, plus the 5 filters = 25 bucks....
85 bucks versus 125.hurah for synthetic.
if it makes you feel any better, jet turbine oil is 50 dollars for one quart, and theyll hold 10 or 20 quarts, and burn a quart ever 10 hours
for some reason I still run castrol gtx....
im done blabbering now.

Oh yea you do not change oil because of brake down crap oil does not lose viscosity, sorry, but you change it do to contamination found from blow by.
woop there it is.

I probably woudnt go 5000 miles per oil change on my rx7, i would stay at 3k. My acura isnt turbo and isnt hard on oil like the rx7, 5k is fine. New cars reccomend 10k+ intervals, now that is excessive...

Driving style, conditions, temperature, elevation... etc... etc... There's ALOT of things that could contribute to that difference of 25-20 miles more per tank.
Now, if you were to put it on a dyno (or something), run it under the same conditions with both synthetic and non-synthetic oil and show me a difference, I'll believe you.
