So you got a new set of wheels – congratulations! You’re going to want to hang onto it as long as possible, so you’ll want to keep it maintained as well as you can. Here are some suggestions:
First, read the owner’s manual carefully and stick to manufacturer’s recommendations for service intervals. There are certain things that are critical enough that failure to adhere to recommendations can void a new car warranty. Don’t let that happen!
For instance, just about every manufacturer recommends synthetic oil for their engines; it provides better protection in just about every respect, and it’s more stable at high and low temperatures. If your owner’s manual prescribes a 10,000-mile oil change, stick with that and be sure to use the bra ...[more]

It would usually consist of setting the ignition timing, replacing the mechanical breaker points in the ignition, cleaning and adjusting the carburetor and replacing the plug wires and spark plugs.

But what about the spark plugs themselves, though? How often do they need to be replaced now?
Manufacturers tout an 80k-100k mile service interval on spark plugs now, thanks in part to improvements in plug design and materials. That might be stretching it, however. Remember that if you have a 100,000-mile spark plug, its electrode is worn down 4/5 of the way at 80,000 miles. A worn ...[more]
