Gearhead RTMOB1 Oil Analysis Test Kit

Gearhead sends you just the right container for your oil sample and another to put that one in, so it isn't destroyed going through the mail. Plus you get a postage paid mailer to send it all in. The results are emailed to you, and the spec sheet is really detailed, informative and professional. Found out my 5W30 synthetic oil was only getting to 10W at 100 degrees Centigrade; invaluable information! I will be using one of their test kits at EVERY oil change from now on. Man, am I ever glad I chose the Gearhead kit. Great guys to speak with on the phone, too. A+++ all around.

Good lab. Good kit. Regular analysis of oil picked up higher oxidation in oil. Unfortunately Mechanic couldnt find problem until it was too late. If high oxidation and you never overheat engine suspect over fueling injector in DD 13/15 motors. It takes 2-3 weeks for info to come back from lab.

never got results
