10 Fuel-Saving Tips
With fuel prices, e-tolls, and other price increases we need to start getting smart and find ways to cut costs. So I’ve collected a few fuel saving tips that could help.
1. Change gears efficiently:
Move up to the highest gear as soon as appropriate. When you drive slowly in a higher gear, you'll burn less fuel;
2. Drive smoothly:
Don't drive aggressively and avoid hard acceleration. You'll burn up to a third less fuel if you drive smoothly;
3. Avoid sudden braking:
Keep a good distance from the car in front of you and avoid braking too hard as this will use more fuel when you have to accelerate afterwards;
4. Make sure your tyres are properly inflated:
Check your tyres regularly and ensure that they are correctly inflated; flat tyres cause more friction on the road putting a heavier load on the engine;
5. Avoid over revving your car:
Don't over-rev when you're pulling away or accelerating. Never 'redline' the rev counter;
6. Avoid carrying excess weight:
Empty your boot out now and again and clear your car of unnecessary items;
7. Switch off your engine when it’s not in use:
Avoid excess idling, it burns fuel unnecessarily. Turn the engine off until you need it again;
8. Use air-conditioning sparingly:
Air-conditioning puts extra strain on your engine and can increase your fuel consumption by 8%. Rather use your car's internal ventilation system where possible;
9. Keep your engine well tuned and serviced:
Service your car regularly - a poorly maintained engine with dirty dark plugs can increase your fuel consumption by up to 50%;
10. Avoid high speeds:
High speeds = more wind resistance = greater fuel consumption. Keep it slow.

Drunk driving, how much is too much to drink?
Drunk driving, how much is too much? This is probably the most raised question in any discussion about drunk driving! The answer to this simple question is unfortunately not as easy, and is determined by what the legal alcohol limit is. The basic scientific answer is to be found in the Widmark Formula:
People often ask how much they can drink before they go past the limit, here is a “basic” answer:
1 metric tot is 8,4 g of ethyl alcohol.
The average beer contains between 13 – 16 grams of ethyl alcohol.
One beer is therefore ± equivalent of a double eg brandy.
In trials all the participants (Male & Female students) exceeded the legal limit = 0,05g/dl after two beers.
According to the Widmark formula:
A = p x c x 10 x r
A = amount of alcohol in grams
p = mass of the person
x 10 = to convert promille ( parts per thousand) to g/dl or g/%
“r” = Widmark factor which is on average 0,7 for men and 0,6 for females.
c = blood alcohol level.
Blood alcohol level = A divided by p x r x 10.
