Comparing AMSOIL Signature Series vs AMSOIL XL

 

Here’s a quick snapshot at some comparisons between AMSOIL Signature Series vs AMSOIL XL:

AMSOIL Signature Series has a higher concentration of detergents and dispersants than AMSOIL XL, meaning it does a better job of cleaning an engine and preventing deposits from forming.

AMSOIL Signature Series performed better in oil breakdown tests, viscosity tests, and sludge formation tests than AMSOIL XL.

AMSOIL Signature Series is designed for extended drain intervals of up to 25,000 miles, while AMSOIL XL is designed for 12,000 mile intervals.

Both AMSOIL Signature Series and AMSOIL XL prevent LSPI events 100% of the time.

It would appear that AMSOIL Signature Series is the better option; however, head over to our oil directory to learn more.

Comparing AMSOIL OE vs AMSOIL XL

 

AMSOIL OE is designed for optimum engine protection and performance in new, late-model vehicles. It is the first synthetic motor oil to earn the API SN Resource Conservation label. AMSOIL XL is engineered for superior performance and protection in extreme conditions, including high temperatures and heavy loads. It is also licensed by the API as a resource conserving motor oil.

Both oils exceed the standards of API Licensing and are emissions control system friendly. However, AMSOIL XL provides better protection in extreme conditions and helps reduce friction and increase fuel mileage.

AMSOIL XL provides 64% more protection against oil breakdown from high temps, 100% protection from LSPI, and extra protection that lasts up to 12,000 miles or 1 year, whichever comes first. If you are looking for a motor oil that will give you optimum performance and protection, then choose AMSOIL XL.

Next, let’s take a look at some filters for the 2012 Jeep Wrangler. We’ll start with the AMSOIL Ea Oil Filter. Then, we’ll discuss the AMSOIL Wix Oil Filter.

The AMSOIL Ea Oil Filter

 

The AMSOIL Ea Oil Filter is designed to provide superior filtering efficiency and extended service life. The filter features advanced full-synthetic media that traps and holds a greater amount of small, wear-causing contaminants than conventional and other high-efficiency filters.

Additionally, the Ea Oil Filter helps reduce engine wear and offers extended service life when used in conjunction with AMSOIL synthetic motor oils. For maximum protection and performance, the filter is recommended for 15,000 miles (24,000 km) or one year in normal or severe service.

The Wix Oil Filter

 

The AMSOIL Wix Oil Filter is designed to keep oil flowing and prevent dry starts. The filter uses an up-front by-pass valve, which is superior to top-mounted valves because it helps to keep oil from washing past dirty media and entering the engine. The glass-enhanced media in the filter offers greater efficiency, capturing more 10 to 12 micron sized particles than other cellulose/synthetic blend media. The filter also has a coil steel spring to ensure internal filter parts are sealed properly.
