Just some rough notes on synthetic oils here.its all i have on my computer right now so sorry that its not the full essay portion of the assignment.
Synthetic Oils.
less thickening at cold temps.
Better high temp. stability.
Costs more.
Start car at lower temps.
Less resistance when car started.
Arctic conditions these are a need.
Usually costs about 3 times more than mineral oil(natural).
Less frequent change intervals.
Easier starting in cold which saves fuel.
- Produced by a chemical reaction.
LIQUIDS DIFFERING WIDELY AS THEIR CHEMICAL STRUCTURE AND COMPOSITION.
Used where properties of normal, natural mineral oil can not be fulfilled.
REDUCES AMOUNT OF DIRTY WASTE OIL NEEDED TO BE DISPOSSED OF.
This oil ends up in landfills quite a bit so the less there is the better.
Created for running automobiles and other engines in real life conditions.
Does not need to be altered to make sure long term engine use and heat will not effect the engine.
Offers best overall protection.
Best in wear protection, all temp performace, best fuel efficiency and extended drain intervals.
Engineered to maintain is lubricating properties at temps. Extreme enough to break down conventional (natural) oil.
detergent and dispersant properties do better job of cleaning out dirt and contaminents.
FIVE MAIN REASONS.
-oil drains can be extended.
-vehicle life can be extended.
-costly repairs can be reduced.
-fuel mileage can be improved.
-performance can be improved.
pure and of uniform size.
designed for sole purpose of protecting your engine.
nothing added if it doesn't improve lubrication.
nothing added if it would contaminate other substances that might lessen the quality of lubrication.
designed so molecules are uniform in size and weight.
Heat + oxidation bad for lubricats.
Contain no contaminents or unstable molecules which are prone to thermal and oxidation break down.
Because of uniform molecule structure they operate with less friction than petroleum oils.
