|Since "microlon" is just another form of soluble PTFE (aka Teflon), I'm sure many people have tried it. |
Go to your local autoparts store and you'll find numerous products (e.g., Slick 50) with PTFE listed as their main ingredient. The problem is, PTFE has been proven ineffective in car engines since it tends to bond to non-moving parts, instead of moving parts.
Nothing to see here, move along folks...
These products have a well established history and are widely documented on the web.
Microlon first and foremost is a ZDDP, zinc dialkyl phospate containing product. This the well know high pressure anti-wear lube additive that has been used for years. 10-15 years ago the API, at the urging of the motor car manufacturers (who have to meet EPA clean air requirements), started lowering the phosphorus content specification for 0W, 5W, 10W weight multi-vis passenger car motor oils. The reason being that it is a (noble metal) catalyst inhibitor which leads to accelerated catalytic converter aging and deactivation.
From its description, Microlon, probably also contains a fluoropolymer (or a modified fluoropolymer, of which Teflon is one) dispersion. These again are nothing new and have been shown to be largely insignificant. You may recall that the purveyors of Slick 50 paid a large fine for false advertising claims about these products.
So, what about the claims for ZDDP? Most all true; it is a proven additive. Is it necessary? This is the Pandora's box. There is good reason to lower the phosphorus content of motor oils (vide supra), however, some claim that you can't make a good motor oil without it. Synthetic oil, other additives and improved metallurgy make up for the lost phosphorus. The debate is fueled mostly by the additive manufacturers, the old & vintage car community (and they are justified, so let them buy things like microlon) and the uninformed who buy and swear by products like Slick 50.
Something to think about: Fact, phosporus compounds will shorten the life of your catalytic converter. The question is how fast. Yes, you may not own the car after 80K, 100K miles, but if you do and have to replace a converter consider what has happened to the price of the active metals in that catalytic converter over the last 2 to 3 years. They have skyrocketed, tripling the cost of a catalytic converter. Just ask your dealer how much a replacement is.
The answer is simple, follow Volvo's recommendations if your car is 10-13 (or so) years old or newer and use an appropriate synthetic oil from one of the major lube companies.
