We all know how the oil is important for proper functioning of the engine. It lubricates almost every moving part, reduces friction and wear of the engines internals and helps cool down the whole unit. And that is just the beginning of the story. Older mechanics often say that engine oils are more important than the fuel. If you run out of the fuel you just put some of it in the tank and you are good to go, but if you run out of the oil, your engine is ruined and you’re not going anywhere.

After a hundred or so thousand miles on your engine, engine internals starts to display a certain level of wear after millions and millions or revs over the years. Moving parts like crankshaft, pistons, valves, camshafts and so on are not longer precisely fitted inside of the engine block or engine head and the car loses compression and therefore performance and fuel economy. In other words, the car is old and tired.

But, what to do?

There are two solutions. One, full engine rebuild with new parts and bore out the block. It is a long, complicated and very expensive process which sometimes doesn’t even makes sense.

Second, fresh oil inside your old engine which will rejuvenate the whole engine in a matter of minutes. It is a fast, cheap and very effective way of bringing new life to old and tired powerplants.

If you opt for the second alternative, we got you covered and here is the short introduction to some of the best oils available on the market which is designed especially for old engines with a lot of miles on them and which will make your car run as new after just one oil change.
