The Importance of an Oil Change
by Paul Dutton
Your car’s oil is the life blood of the engine; I cannot stress enough, the value of this simple maintenance procedure.
Consider regular oil changes to be like really cheap insurance for your engine. Even a few high-quality oil changes will seem like pocket change compared to replacing camshafts or pistons!
Simply put, engine oil provides three key functions in a modern internal combustion engine; it helps keep engine components working smoothly… together, it helps draw heat away from the combustion chamber and it helps prevent carbon and varnishes
from accumulating in the engine.

Don't Touch the Glass when Changing Headlight Bulbs
Most headlight bulbs now are filled with halogen and have special coatings on the outside of the glass. If you pick up the bulb by the glass with your fingers, you will leave trace amounts of oil and grease on the glass.
When the bulb is used, that area of the glass will get hotter than the rest and it will eventually cause the bulb to crack. When changing headlight bulbs, only hold the metal bulb holder at the base, or make sure you're wearing rubber surgical / mechanic's gloves (clean ones) if you're touching the glass.
Disconnect and Reconnecting your Battery
If you're going to do any work on your car involving the electrical system, disconnect the battery first. To do this, loosen the connector for the negative/ground terminal first, and wiggle the terminal cap off. Use a wire-tie or similar to tie the cable back out of the way. If you need to take the battery out, you can now take off the positive connector.
Why negative then positive? If you disconnect the positive side of the battery first, the negative side is still connected to the entire car. If you drop a tool and it lands on the positive battery terminal and touches anything else on the car, you'll have an electrical short. By disconnecting the negative first, you're cutting off the return path for the current. Now, if a tool drops on to either of the battery terminals, it doesn't matter if it touches part of the chassis or not - there's no continuous path for the electrical current.
Reconnecting your battery. Connect the positive terminal first, and the negative second - the reverse of removal, and for the same reasons.
When you slip the negative connector on, there will be a spark as it gets close and makes contact with the negative battery terminal. Don't be afraid of this - it's nothing to worry about. Make sure the terminal caps are done
up nice and tight.
