What Oil is Best for My Used Vehicle?
Similar to car shopping, oil shopping can become overwhelming as well. A host of brands are marketing a flurry of oil options, each of different grade and quality. Then comes the Hebrew-like numbers strewn all over the container, each with a specific meaning that you do not know. But you do know that you just cannot buy any random oil. You have heard that the quality of oil you use in your car affects engine performance, longevity, and gas mileage. The priciest option is not always optimal and the cheapest is not suggested. So, how do you decide which type of oil is indeed good for your car?
Read the owner’s manual
A good dealer will direct you to the owner’s manual after you have bought one of their used cars with bad credit to get most of your answers. All manufacturers suggest a specific rating of viscosity and quality that you must use in your car. For instance, if you see the figure 10W-30 written in the manual, this is your answer as to which container to pick in the gas station. The manual may also suggest something like – API certified oils. Look for a badge then with the words “American Petroleum Institute” and/or “API Service SN” on the container that you are about to pay money for.
Understand oil viscosity
The 10W-30 etching that you see on oil containers (and on the owner’s manual)definitely means something. But there maybe times when your selected dealer selling high-quality buy here pay here cars advises you to use an oil with 10W-40 or 5W-30 rating. The numbers you see placed before and after the letter “W” are the viscosity ratings of the oil at zero and 212 degrees respectively. In simpler words, they are a measure of how resistant the oil is to thickening during winters and thinning during summers. A lesser number before “W” means that the oil will thicken less while a higher number after “W” says that it will thin less.
Now, how do they matter? Thick oil is necessary to keep the moving parts of the engine well-lubricated. Then again, thick oil is harder to transport from the oil tank to the engine and makes it difficult for the crankshaft to move freely. Thick oil also attracts dirt and forms easy sludge. As evident, thin oil has the opposite effects. It cannot lubricate well, flows easily to the combustion chamber, and more.Your oil needs, thus, will change with seasons. You will want to buy an oil that is optimal under both hot and cool conditions and thicken or thin to the perfect extent. During extreme winters, a 5W viscosity rating is suggested. For scorching summers, 10W-40 works fine.
Select the type last
Once you have tested API certification and decided on the viscosity rating, you will have to decide on the type of oil you will want last. Hover around the following options during your visit to the gas station.
-Premium or high-performance oil: Most oil producers sell these in varying viscosity grades. The oil is generally SL certified, which means that the type passed API’s modern testing parameters. Perfect for light-duty vehicles and family sedans.
-Synthetic Blend: These oils are a mixture of a chemically manufactured high-quality synthetic oil and standard organic oils. They carry the efficient properties of synthetic oil in combination with the lower price tag or mineral oils. Buy these if you drive a heavy-duty truck or bulky SUV.
-Fully Synthetic: Manufactured in laboratories, these oils radiate quality. Right from high fuel efficiency to sludge protection to optimal temperature tolerance, synthetic oils are a dream of car engines. However, they are the most expensive on this list and are meant for owners of Mercedes, BMW, or Corvette.
-High-mileage: Top used car dealerships suggest these oils to customers who went home with a vehicle that already has over 75,000 to 100,000 miles on them. They are specifically formulated for older engines to give higher protection against wear and tear.
You may also choose to go for oils that have different additives to enhance performance. But treat them like car add-ons that you are offered while shopping for bad credit cars for sale.
Manufacturer’s suggestion, viscosity rating, and oil type – that is all you will have to remember. Ticking these boxes will direct you to the best oil that you can put inside your car. Apart from that, maintain the oil and oil filter change schedules, get a thorough engine servicing once in a while and your car will perform like no other. Buying the right oil is really not that difficult.
