You should start using synthetic oil right away. The engines in today's cars don't go through a "break in period" like older cars did because the cylinders and pistons are machined to very tight tolerances. Advancements in CNC machining centers and materials have eliminated the traditional break in period. That is why today's engines will run for more than 300,000 miles compared to just 25 years ago when a car with 100,000 miles on it was considered scrap. However, you should still change the oiland filter as recommended in your owner's manual. Some people mistakenly think that they don't need to change their oil as often if they use synthetic oil. This is wrong because contaminants from the engine's combustion still get into the oil and the only way to get rid of it is to change the oil & filter regularly.
I dodged the bullet on that one by not using synthetic oil in my car. If I did, I would be sure to change it at least as often as my owner's manual stipulates so I don't void my warranty.
Yes, VW recommends using synthetic in this car.
It would not be as good as all synthetic however mixing the two should not do any damage to your engine.

your car should still start, regardless of the alarm It depends on the alarm, some can cause a no start.
Some cars as well as aircrafts use synthetic oil. Whether you should use it in your car or not will depend on the age of the car as well as its milage. If its too old, its probably not a good idea.
It is not a very god idea if that is what the manufacture requires, conventional will leave sludge and gunk in the engine.
There are many things one should do when their car doesn't start. Depending on the type of car one has, one should check for problems located in their engine.
Every 3,000 miles is when the oil should be changed on a motor vehicle using standard oil. If the vehicle takes Full Synthetic, 5000 miles is the oil change interval.
close all of the door then lock and unlock them>alarm should stop nd car should start
You should change your oil as recommended by the manufacturer. You change the oil because it gets dirty and the type of oil you use won't change the fact that it will get dirty.
Three possibilites why the car won't start after using the battery when the car is off. (1) the battery may be old and not holding enough charge to re-start the car (2) the belt that drives the alternator may be loose (3) the alternator may be faulty.
