"Oil additives, you know the ones that almost everyone has tried and most have not seen much difference, Yea those. Lets talk about what is really in them and what they can do to your engine.
There are hundreds of oil additives on the market. Some say that they will reduce your mileage, or reduce your wear, or reduce your oil consumption, and some even say that you can run your engine without any oil after treating your engine with their miracle cure additive.
The truth is that there are 4 types of oil additives.
Solvent is one and it only cleans out deposits left by using a poor oil. If you use a good oil you should not need to use a solvent in your engine. Think about it, there is many places in your engine that dont drain all the oil out of. You know the small little valleys that hold the oil and doesnt drain oil. That still has the solvent it them and will contaminate your new fresh oil. Solvent will clean out your engine but at what cost? Solvent is made to break down oils and I for one would never use a solvent in my engine because it would start to break down my new fresh oil and reduce the oils ability to properly lubricate my engine.
