The Fram tough gaurd is a very good filter, only drawback is the paper end cap which really isn't that big a deal. It has one off the best filtrations (98% SPE, syntetic glass media) out there and is very reasonably priced.


"FRAM® Tough Guard� filter with the SureGrip® feature

If you're doing a fair amount of off-roading or tow a trailer frequently you need to pay special attention to your engine's cleanliness and use products formulated for these tough driving conditions.

FRAM® Tough Guard� filter protects your engine when operating in such tough conditions as:
Extreme hot or cold
Stop-and-go traffic
Unusually dirty roads
Heavy loads and towing


How Does it Work?
The FRAM® Tough Guard� oil filter features a number of advanced characteristics including:

1. Screen-over by-pass valve: Provides back-up filtration for the times when the filter might become clogged in extremely dusty or dirty conditions or when oil flows through the by-pass valve during cold start-ups. The screen provides added protection and insurance against larger, problematic particles of dirt until you change your filter!

2. Synthetic glass and cellulose media: The most advanced feature is the filter media which is a combination of synthetic glass and cellulose uniquely formulated for top-rated efficiency for the life of the filter. Tough Guard filter has even more synthetic glass and cellulose than FRAM® Extra Guard® filter for an even greater life and efficiency with an SPE of 98%.

3. Silicone anti-drainback valve: This design allows the filter to retain oil when your vehicle is turned off so your engine benefits from a filter full of oil at startup. Constructed of silicone, the gasket remains flexible and continues to perform even in extreme heat.

4. PTFE-coated exterior gasket: Reduces friction making it easier when removing the filter. "

The regular orange fram (extra gaurd) is the one that sucked in the comparisons. And don't waste money on the ddouble gaurd as it's a normal filter with snaake oil PTFE in it.
