How to Buy the Right Oil Additive for Your Car

Anyone searching for topnotch engine oils can search the Internet for a variety of types of oil and quality branded products. In particular, you should look for oils of different viscosities and types. You might also err on the side of caution and simply purchase a popular brand, but the true car enthusiast would do his research in knowing what additives are included in his lubrication to get the most out of his oil investment every time.

What to Look for in Oil Additives

Oil additives range from simple cleaners to complex ones that alter the properties of the oil itself. Regardless, they're usually listed right on the bottle from which they came. These additives are important because they help improve engine performance and mitigate the usual downsides of oil usage. They're particularly useful in modern cars or older vintage vehicles that require an extra hand. Here are just some of them.

  1. Improve Viscosity Index (VI): Oils tend to thin out at higher temperatures, so you should have the VI additive in it to prevent this phenomenon from happening and keep your oil at just the right thickness at all times.
  1. Pour Point Depressants:Oil tends to congeal in cold temperatures (as anyone with cooking oil in winter would attest), so to prevent your oil from becoming lard, it should have pour point depressant additives added to it.
  1. Detergents: There are oils that come complete with detergent additives in order to clean out your car like your laundry detergent would. They particularly prevent clogs and remove any and all engine deposits.
  1. Dispersants: As for the dispersant additive, it disperses dirt fromdirty oil found in the sump of your internal combustion engine, which mitigates sludge formation. It also works hand-in-hand with the detergent additive to clean out your oil.
  1. Anti-Wear Agents: Oil with anti-wear agent additive helps not only lubricate your car parts and reduce friction; it also serves as coating that protects all your metal surfaces.
  1. Friction Modifiers: Speaking of friction, friction modifiers are additives that make your friction-reducing lube even better at its job, thus improving fuel economy and consumption.
  1. Antioxidants: If you want to prevent your oil from thickening and clogging up your car (especially during the cold months), then purchase oils with antioxidants in them.
  1. Foam Inhibitors: Oil foam bubbles can reduce the effectiveness of your car performance, so your lube should have foam inhibitors to make sure that it doesn't end up making a bubbly lather inside your car parts.
  1. Rust or Corrosion Inhibitors: This is a common addition to oil that helps the metallic parts of your car from corroding and rusting due to oxidation and moisture. Even if your metal parts have finishes on them, finishes wear down, so it helps to have anti-rust properties in your oil

In a Nutshell

You can choose oils based on the oil specifications preferred by your car. You can also base it on your budget and get a modicum of necessary additives for your oil formula. As a rule of thumb, it's better to choose one additive or two rather than too many because too much ingredients (like cooks) can spoil your oil broth, as the turn of the phrase goes. To be more specific, certain additives don't interact well with one another, resulting in thinning oil and an excess of additives that don't do much because there isn't much oil to go around. Additive usage should be taken moderately.
