what are the ingredients in engine oil?

Question

We use engine oil for lubricating the engine. Different oil is used for different engines. Namely 2T, 20/50 and so on...

Answer 1

Of course first of all, it has the oil itself, - but it also has a number of additives that are put in to keep your engine clean and to "move the impurities" on into the oil filter (which hopefully removes them form the oil!l) Among the additives are detergent agents (unless non-detergent oil), anti-acid ingredients, stabalizers (they help keep the viscosity up when it gets hot). Some also have "mettalic additives" like molibdiumum., and chrme among others!

Now oil doesn't really wear out, it just gets full of dirt, grime, and carbon. Plus the additives are consumed or lost.

Years ago, I used to have a 55 gallon drum that all the oil went into, and after 6 months to a year, you could dip out a container of oil, and it would be "clear", -- all the oil had the dirt and impurities had settled to the bottom. Then this oil was "good as new" as far as oil went, -- after that we just added a can of "additives" like alemite CD-2, - or Rislone, and it was ready for several thousand miles more! Later on (after I got married 40+ years ago), I would take it to a oil "reclaiming" place in town, you took in a 5 gallon can of oil, and exchanged it for 5 gallons of re-claimed oil, -- this oil cost about 25 cents a quart, all you had to do from there,- is put in your additive and away you went . But now we are "saving the planet" by doing away with this oil in some other fashion, - so now we have to have a steady supply of "new petroleum" oil to make new oil from!--- I guess they think this saves the planet somehow!

The "multi grade" oils have a stabalizer in the mix, - that makes it act like a low "weigh"t when it is cold (great for sub zero temperatures), - and stay up in viscosity so that it acts like a higher "weight" oil. For instance 10-30 acts like 10 weight when it is cold, but 30 weight when it is hot. The hotter the "normal" oil is , - the thinnner it gets! The "thickness" of the oil is called "viscosity". Most all oil companies use some of the same things, but at the same time the individual brands use their own blend of stuff too!

Answer 2

Engine oil basically does 3 things: Lubricates, Cools and Cleans.

Except synthetic like Mobile 1, Engine oil has mineral oil to lubricate.

It also has detergents and "suspension additives" to keep the engine clean. The suspension additives cause dirt to be "suspended" in the oil rather than "deposited" in your engine. This is one reason it is important to change your oil frequently. When too much dirt is suspended in the oil, it can start to cause engine wear.

Other chemicals are added to keep it at a certain thickness ("weight" or "Viscosity"). The numbers (like 5w-30) describe how thick the oil is at different temps.

Even though most cars have water cooled engines, Motor oil also plays an important part in cooling the engine too. The heat from the friction is carried back to the oil pan under the car and cools of before recurculating.

Other additives help the oil to last longer. If we just used straight mineral oil, we’d need to change oil every week or every 100 miles or so. Even then, the oil wouldn’t work as well as modern oils work today.

There is a grading nomenclature (based on Oil chemistry) for Engine Oils - try to use the one recommended by the vehicle manufacturer or the one that matches it, FYI-

Answer 5

The exact formulations are trade secrets.Some contain detergents,silicas,etc. the designations of 10w30,10w40 etc. refer to the viscosity of the oil.The first # refering to the weight of flow when cold and the second# to the weight when hot.Synthetics are man made oils using the same viscosity formulas.They are more expensive but in my opinion worth the money.

Answer 6

Most are petrolium based Fossl fuels. With detergent added. Synthic is simply that a made made oil.

Answer 7

oil is the ingrediant in oil. different oils have different consistencies....but oil is oil.

Answer 8

believe it or not, the way they get a multi viscosity oil that is not a synthetic, is with wax
