- Reduce engine temperatures
- Maintaining proper engine function
Automotive technology has come a long way since the mid-20th century, and so has motor oil. A 1940s-era car didn’t feature an oil pump or oil filter. Instead, they relied on dippers on the crankshaft’s counterweights, which would then sling oil to coat crucial moving parts. Motor oils in those days weren’t designed with detergents and other additives to help keep the engine clean; even with frequent oil change intervals, many cars would be in need of an engine overhaul by the time they reached 80,000 miles.
Today’s motor oil formulations incorporate additives to suspend contaminants in the oil so they can easily be trapped by the oil filter. Here are a few other facts about motor oil you may not have known:

If a tune-up sounds like a simple thing, you’d probably be surprised that many car owners actually forget to have one done regularly. In combination with other preventative maintenance like transmission flushes and oil changes, tune-ups can extend the life of your vehicle by inspecting and restoring vital engine parts. Tune-ups should be done at regular intervals, about every 30,000 miles, and especially in older vehicles. Things wear out overtime, so even if it’s been a few years, you may want to ask yourself: When was the last time I checked my hoses and gaskets? Are my sparkplugs still in working condition? How long has it been since I’ve changed the air-filter or fuel-filter?
Tune-ups can not only replace worn parts they can save you time and money in the long run by preventing costly future repairs, and boosting the performance of your vehicle. If you’ve noticed any of the following, it’s p ...[more]
