Signature Series cleans up the competition
In general, the higher an oil’s TBN, the better its ability to neutralize contaminants such as combustion by-products and acidic materials. Higher TBN oils neutralize a greater amount of acidic material, which results in longer oil life and cleaner engines.
TBN levels decrease as the oil remains in service. When the level reaches a point where it can no longer protect against corrosion, the oil must be changed.
The Total Base Number Test (ASTM D2896) uses a series of chemical reactions to measure the alkaline additives in a motor oil. We recognize the value of formulating motor oils with high TBN, and AMSOIL Signature Series Synthetic Motor Oil features the highest TBN of the oils tested.
AMSOIL Signature Series is fortified with a heavy treatment of detergent additive and it delivers 30% more acid neutralizing power1 than Mobil 1, and 36% more than Royal Purple, helping engines to stay cleaner, longer.
The AMSOIL Advantage
AMSOIL synthetic lubricants feature a large dose of quality additives that consistently deliver high TBN for the life of the oil. They neutralize acidic contaminants and keep them in suspension to maximize engine protection. AMSOIL lubricants use detergent and dispersant additives to significantly reduce sludge and carbon deposit formation. In the Total Base Number Test (ASTM D2896), AMSOIL Signature Series 5W-30 Synthetic Motor Oil demonstrated the highest TBN of the oils featured in the test, helping it deliver reliable protection for extended drain intervals. One thing the test doesn’t show is our detergent lasts longer. You can see that for yourself when you pull your own oil analysis.
Aftermarket Additives – Did you know?
Just by adding your aftermarket oil additive meant to help with “something”, these additives are used because the user believes it offers an additional attribute which the base motor oil does not offer. With AMSOIL you never need to do this. Anything offered on the market was reviewed often decades ago and if it offers some advantage it will be in the AMSOIL product. If not you risk neutralizing additives such as the detergents which make up the largest part of the price of AMSOIL other than the base oil.
There are several additives which took decades of knowledge to get them to perform together without nullifying the benefits. That’s what aftermarket additives do, they often make a good oil worse than bad. After the additive is added you may have just been better off getting your oil at the dollar store or just using the used oil out of your sisters old Saturn. (Assuming it still runs because she didn’t use any of these caustic additives)..
Research the brand and even their address
Note – research the company you buy the additive from. One very big one which in the 60’s had their name on Indy cars, etc has been on the FTC’s warning site more than once and has actually been bought and sold no less than 6 times. Each time it becomes a totally different product. Others actually do some good but at the same time are causing a greater negative in the oil somewhere else.
