They both have advantages and disadvantages.For cars, Front Wheel Drive or Rear Wheel Drive is better?
What do you want from your car? Are you a race-track enthusiast? What's your style of driving? RWD usually have better weight distribution and thus better handling, but I would say that unless you're heavily into performance cars, FWD would probably be adequate for need (which is why the vast majority of cars are FWD).For cars,
Front Wheel Drive or Rear Wheel Drive is better?
Front wheel is better in my experience. But there was a learning curve when switching from rear wheel to front wheel in snow/ice/slick conditions. After I got used to that, it was easy to say front wheel is better. Sarkus is right with the weight giving added traction.For cars,

FWD is better. If you can get an AWD, that is the best. Subaru makes them. Problem is, they cost a fortune.For cars,

River aptly demonstrates the other dynamic you will need to deal with on an icy road; people in large vehicles they can only marginally control attempting to have "fun" with them in hazardous conditions instead of a sled, or a vehicle that is designed to afford better control in the snow. Steer your vehicle clear of these idiots by a wide berth.RWD drive is more fun . in snow besides the safety issues.
Subaru is a very good and top rated mechanical design for their AWD vehicles. I drive a Forrester. Stop by the Subaru dealer and check out the models of drive train designs for other FWD and AWD from other manufacturer's vehicles compared to Subaru. For almost all but Subaru, it is a study in asymmetrically weighted and sculpted drive trains. This will have the undesired effect of an imbalance of control as well as ASSYMETRICAL LOADING OF BOTH THE TIRES AND THE ENTIRE DRIVE TRAIN. This will place undesirable stress on the component carrying the heaviest load, and this will make itself known over the service life of the vehicle. Uneven tire wear will be the first thing you notice, but along with that comes asymmetrical driving characteristics. Such things do make a difference in terms of both handling and safety.FWD is better. If you can get an AWD, that is the best. Subaru makes them. Problem is, they cost a fortune.
Using fully synthetic oil, how long can it last? 15k KM ?
Its not so much the oil it's self lasting ; since synthetic oil has no wax ( which conventional have ). It is about the oil filter itself lasting.
Synthetic oil is the best oil to use hands down. It is very difficult to break down synthetic oil, very difficult.

Using fully synthetic oil, how long can it last? 15k KM ?
Synthetic is a waste of money. Just use regular oil, it costs less, and every 3000 to 5000 miles change the oil and filter. By doing this the viscosity of the oil won't degrade very much so that your engine will be protected as long as you remember to change the oil and filter. The filter gets filled with dirt and debris so the sooner you change it the better your car will last. Fram makes very good filters and I try to buy that kind to replace my old one with.
The normal recommendation for a 1990 Honda Accord is changing the oil and filter every 7500 miles. Fram, a filter manufacturer, identifies "severe" factors as short trips of less than five miles, carrying maximum loads, operating in severe dust conditions, stop and go driving, excessive idling and other conditions. The same 1990 Honda Accord manual recommends the owner change the oil every 3750 miles for severe conditions. If your vehicle is older, this may dirty the oil faster too. As gaskets and other parts in the engine compartment age, they may deteriorate and leak in dust and other contaminants.
Not true about Synthetic being a waste of money. You will get more protection at start up, and in cold weather with a full synthetic oil. Normal oil is thicker at start up, and takes longer to reach the optimum viscosity for your engine.
