We all use it, but who knows which type is best for our cars. Motor oil is something that helps keep engine parts lubricated and running in good condition. Most cars hold about 5 quarts of oil at any given time and it's recommended that you replace or change your motor oil every 3000-4000 miles. Newer cars don't require such frequent oil changes, but older model cars will run smoother and get better gas mileage if the oil is clean and new. For years people changed their motor oil at home in their front yards or garages and actually went to the store to buy the motor oil themselves. Nowadays, we just have some company do the oil change for us for about $30-$40. Jiffy Lube is an oil change company that has stores all across the U.S. and will do oil changes for pretty cheap. You can buy motor oil in your local automotive parts store or online. The most popular motor oil brands are Red Line, Motul, Royal Purple, Mobil, Pennzoil, DuraLube, Castrol, Kendall, Valvoline, Amsoil, Quaker State, and Havoline.
Oil comes in 5W-20, 10W-30, 10W-40, 5W-30 (different weights as they are called). Your car manufacturer can tell you which type is best for your car, check the owners manual. We prefer Pennzoil High Mileage Vehicle Motor Oils for older model cars. They help restore engine performance and extend the life of the engine. You get "enhanced protection" for worn engine parts and it helps condition seals in older engines. When you buy a case (12 quarts) you can often get Pennzoil for about $.75 a quart. Motor oil comparisons have been done through the years and no significant data has come through these studies. We went online to read some motor oil reviews and motor oil ratings only to find that each car owner preferred their own particular type of motor oil for various reasons, none of which appeared to be scientific or eye opening in any way. When I take my 1993 Saturn down to the local oil change shop called "Oil Can Henry's" I don't get much of a choice so I usually go with the Castrol Synthetic during the winter months and regular Castrol other than that. In all the online articles we read, no person ever claimed that a certain type of motor oil caused them engine problems. The bigger complaints came against oil change shops that did bad jobs or forgot to put the drain plug back on tight which caused severe oil leaks. Most consumers said that any major brand name will work just fine and that the cheapest motor oil is usually found by using coupons found in your Sunday paper that will let you purchase a quart of name brand oil for about $.50. RECOMMENDED - We suggest buying motor oil in bulk since you will use at least 3 to 5 quarts on most oil changes. One of the top sellers on Amazon is the Royal Purple Street Synthetic Motor Oil - SAE 5w30 which comes in a pack of 12. You can browse all the top selling motor oils on Amazon.com here.
Synthetic Motor Oil:
Synthetic motor oil has been pushed recently as being better than regular motor oil. Synthetic motor oil was developed for high performance racing engines and is good for vehicles with high performance engines and it works well in extremely cold climates. Other than that, there are no proven advantages to using synthetic motor oil versus regular motor oil although many oil change shops would like you to believe that. Synthetic motor oil is considerably more expensive than regular oil and if you choose to use it during your oil changes, the cost may exceed the benefits. The best synthetic motor oils on the market are SynPower from Valvoline which works great on performance cars like BMW's, Corvettes, Lexus, Mercedes, Porsche, Volvo and Audi. We have also heard great things about the SAE 10W-40 Synthetic High Performance Motor Oil from AMSOIL - works in both gasoline and diesel engines, good high viscosity oil, handles the most severe automotive driving conditions. It sells for about $7/quart and can be bought online or at your local Auto parts store. See an entire list of synthetic motor oils on Amazon here.
Oil Changes on Cars - DIY:
The dreaded oil change. Do you take on the task and do it yourself or let a chain store like Jiffy Lube work on your car. Oil changes used to be easier to perform at home when cars engines were more accessible. Some makes and models of cars today make oil changes almost impossible for the DIY. Most car manufacturers recommend changing the oil every 3 months or 3000-5000 miles. We have heard so much that oil changes every 3000 miles are a myth and it appears they are right. Unless you have an older model car that used oil up fast or requires more frequent oil changes, 5000 miles will do just fine. When you change the oil, you don't need to change the oil filter at the same time (unless it looks dirty). First, start by locating the oil drain plug and place the oil drain pan under the plug. Then slowly loosen the drain plug with a socket wrench and eventually remove the plug by hand as it gets looser. As you remove the drain plug, oil will come out and if it's hot make sure you are wearing gloves to protect your hands. Wipe the drain plug and the plug opening and replace the drain plug gasket before reinstalling the drain plug. Tighten the oil drain plug with a wrench (this step is probably the most important), but don't overtighten. Check the oil filter next and replace if necessary being careful of any excess oil that may still remain in the oil filter. Once the oil has been drained and the oil filter replaced, then proceed to the oil filler cap on top of the engine and remove it. Use a funnel to pour in the new oil - usually about 4 to 5 quarts. Replace the oil filler cap and run the car for a few minutes, then check your oil dipstick and add more oil if it needs it. Make sure there are no leaks around the drain plug area as this is a common mistake made even by the oil change shops. Mark the date and mileage on a sheet of paper so you know when the next oil change should occur. Oil changes are one of the few do it yourself activities left on modern cars and it should only take about 30 minutes (1/2 hour). If you do decide that taking it to a shop is easier, we recommend going to the dealership first since they tend to do better work than chain stores (per reviews by car owners). If you do go to a oil change service like JiffyLube, check online or in your local paper for coupons.
