Fluid service testing
I came across something today called Radial Planar Chromatography. Basically you drop oil on a special cloth and read the circle.
Why and how did I find this? Several customers have asked or mentioned “the dealer/other shop/mechanic said I need X fluid service.”
No problem. I always ask why. Most people don’t know why. That’s when I would normally go to Alldata and pull up the maintenance schedule. Then the conversation goes “you’re at 160k, it’s time for that service based on mileage.” Or even worse they’ll say “I think I need x service” and my response is “if there’s no record, then it’s probably a good idea to do it.”
Now with this, it gives more of a visual confirmation. People LOVE pictures and fluid service is high profit. Oh and if you offer pre-purchase inspections it’s good money there too!
