The one concept that help me feel completely comfortable with me decision was filtering/dewatering wvo. GFS really pushes filter on the fly and to rely on your vehicle filters. I've come to the conclusion that cleaning your wvo is best done off the road. Once you forget about the "one shot, single shot" program, GFS only has their tanks.
On road filtration is a disaster waiting to happen. Really, what do they (GFS)think you are going to do: Pull up behing Joe's diner and RIP HIM OFF? The contents of the grease receptacle IS NOT the property of the restaurantuer once deposited. Helping one self to its contents, with or without the consent of the owner/manager/cook is THEFT.
After collecting tens of thousands of gallons of WVO, and having agravity fed CF for nearly 6 years, I can tell you that a spin on filter, water blocking or not, will NEVER clean oil to a safe (500 PPM) water level. Period. A pipe dream, at best. Not to mention contaminants, detergents/cleaners, caustics, etc.
downside to vegistroke is price and customer service. Another option to get you going is Greasecar kit.
OMFG NO! Dont do it. I started with one. The Greasecar PSD kit is a highly under engineered POS obviously designed by someone who has absolutely NO F'ing clue what it takes to safely operate the HEUI injection system on ANY fuel! That system is only worth the value of the tank ($500) and the filter housing ($200) in my opinion. If you need the rest of the pieces they provide, let me know. I will happily sell them to you for half of their value......which is near NOTHING. Them boys should have quit after designing the kit for the VW 1.9L ALH engine. It takes very little smarts to realize that these thirsty 7.3 cannot be reliable supplied by an improperly located stock pump, and PULLING THICK OIL THRU THE FILTER.
Of course this is just my opinion, I could be wrong.
