Nothing serious will happen to your engine although you may not get the
full benefits of what is claimed for each brand of fuel if you mix. Each
petrol company has its own additive package and so if you mix, you will
dilute it and it may not provide maximum benefits.

Engine oil grades like 15W50 refer to the thickness of the oil in cold
and hot operating conditions. All you need to know is that the number of
the left of the W refers to how thin the oil is in cold conditions and
the one on the right refers to how thick it is in hot conditions. This is
called a multigrade oil and you should choose a balance for your car.
Fortunately, in tropical climates like Malaysia, the temperature
variations are not great compared to those in England where you have high
temperatures in summer and very low temperatures in winter. In the past,
people had to even change oil grades for each season but now multigrades
allow one oil to be used all year round.

There are grades going from 0W40 to 20W50 and for some engines, the 0W40
may be a bit too thin and the oil could get burnt up easily, requiring
topping up. Older engines, which had bigger gaps between parts, may
require a thicker oil.

You can try various ones and see which suits your car but all reputable
brands are fine and should not cause any engine damage. If you have an
Owner's Manual available, it will tell you the recommended oil grade to
use.
