We're Caren and Neil and we just purchased and modified a '99 Suburban with the Greasecar system. We've since learned quite a lot about veggie oil and car mechanics, and we are a lot happier driving around the country burning a renewable and more environmentally friendly resource. Your tech support has also been very helpful in trouble-shooting and allowing us to fix any snares on our own.
Yay! Great investment for us and our future, we have a baby due next month!
