The 2017 SEMA Show in Las Vegas was a great success.  We had lots of booth activity, previewed several new products, and won a SEMA Global Media Award for Best New Engineered Product for our Filteröl Bypass Filtration System.  Our Show specials are listed under the tab marked SEMA 2017 and will continue until December 15. Please contact us directly for these  specials.  Talk with you soon...


Grit happens.  TopDog-V provides state of the art asset protection for your engine.  TopDog-V is a bypass filtration solution that finely cleans your oil, is quick to install, requires no engine modification, and offers significant economic and environmental benefits. 

Ensuring the cleanest possible oil is the most important step you can take to protect your engine. Making frequent oil changes is expensive and time consuming; and waiting too long between changes can be disastrous. TopDog-V diverts a small amount of oil to a bypass filter for “super-cleaning.” The oil is then sent directly into the engine gallery. 

The most important economic and environmental benefits include:

  • Improved mileage (up to 8-10%)
  • Increased horsepower (higher efficiency, less energy consumption)
  • Extended oil service intervals (at least two to three times longer)
  • Longer engine life (decreased wear rate approximately 70%)
  • Lower repair costs (less parts replacement and labor costs)
  • Reduced emissions (up to 15%)
  • Fast, easy installation, with no engine modification required

The fitted System Adapter and Nipple are the heart of the TopDog-V system

  • Dipstick @ 30,000 miles
  • 10-40W Oil / No oil changes
  • 1 full-flow oil filter change

Our research found a vehicle traveling about 14,000 miles per year, getting about 18 mpg, could recover the cost for a TopDog-V Kit in under  nine months.  

TopDog-V Installation on a 2008 Toyota FJ Cruiser.

A Blackstone Lab oil analysis of our 30,000 mile test for wear metals in parts per million (ppm) on a 2008 Toyota FJ Cruiser is shown on Table 1 (see dipstick picture above). At 30,000 miles, the bypass filter  was still hot to the touch, meaning the filter was still working, not clogged. The comparison of wear metal ppm to acceptable levels confirms that TopDog-V removed and held contaminants to a remarkable degree. Note that this was a controlled experiment. We recommend that you never travel this distance without making oil and filter changes.

TopDog-V has received many awards and peer recognition from industry leaders technical editors, including SEMA, Four-Wheel Drive, Diesel World, Cleantech Open National Competition, Cal-Tech Green Entrepreneurs Forum, NORIA, and others.

TopDog-V Kits are sold ready for installation, including two Donaldson Bypass Filters, (see Pricing for details).

Since TopDog-V is vehicle-specific, we need to know your full-flow filter make and model, the vehicle year, make, model, and engine size to ensure proper fitment.   We can provide Kits for engines with canister-type oil filters and are working to develop an attractive pricing package.      

Please feel free to call us for any questions you might have. We can take orders over the telephone or by mail until our store is completed. We take most major credit cards and delivery can be as short as three to five business days.
