Mercedes calls their unit a “Flexible Service System”. The FSS on some Mercedes vehicles monitors actual oil quality as well as operating conditions (such as the number of cold starts, average engine temp, mileage driven, oil sump level, rpms, etc.). To measure oil quality, there is actually a sensor that measures the electrical conductivity of the oil. The higher the conductivity of the oil, the greater the need for an oil change, according to Mercedes. Of course, this isn’t likely a perfect model, and will not be nearly as accurate as an actual oil analysis in determining true oil quality, but it is better than no measurement at all.
At any rate, as electrical conductivity increases, this value is combined … Read the rest

You have probably heard this a million times before, but this particular point ears repeating, especially if you live in a climate with harsh winter conditions. Oil designed for cold weather use cannot provide proper lubrication in hot weather because it thins out too much. Replace the oil with the grade recommended for summer use, and don’t forget to replace the filter as well.
If your wallet can stand the extra strain, replace the oil with fully synthetic oil, even if it is not specifically recommended by the manufacturer of your vehicle. Synthetic oil remains stable under a wider range of temperatures than regular mineral oil, with the added bonus that it provides almost twice the lubrication … Read the rest
When it comes to changing the oil in one’s car, the first thing needed is to consult the owner’s manual to find the type of filter and how many quarts of oil are needed. Other items are a good drain pan, and funnel. These can be purchased at the auto parts store. It’s a good idea to have a basic set of tools. An extra tool that makes oil changes easier, in my opinion, is an oil filter wrench (specialty tool). I use a socket and ratchet set when I change oil. I’ve also known people who would use an adjustable wrench. I don’t consider this a good idea because you can slip off of the drain plug and damage … Read the rest
Petroleum oil begins to break-down almost immediately. A high quality synthetic, on the other hand, can last for many thousands of miles without any significant reduction in performance or protection characteristics. Synthetics designed from the right combination of basestocks and additives can last indefinitely with the right filtration system.
As alluded to above, the first major difference between petroleum and synthetic oil is heat tolerance. Flash point is a technical specification referenced by most oil manufacturers which is an indicator of heat tolerance.
The lower the flash point of an oil the greater tendency for that oil to suffer vaporization loss at high temperatures and to burn off on hot cylinder walls and pistons. This leads to oil thickening and … Read the rest
Choosing the most suitable motor oil for your car is the aspect that should not be disregarded. This is because not all the oil types fit one and the same vehicle and some of them may even affect the way the auto will function. There are a few important questions you need to answer before shopping for the best engine oil brand. These questions concern the type of the vehicle you own, its age, manufacturer’s guidelines and the weather conditions that prevail in your location.
To start with, it is essential to recollect the type of engine oil you have been using before. If you have never inquired about this issue or if this is the first time you have … Read the rest
