Did diesel fuel end up in a gasoline tank by mistake?
If you THINK there is diesel or other contamination in your gasoline tank you need to KNOW for sure or risk engine damage. To be 100% sure of contamination you must send a sample to our lab. The lab will send you the special shipping container and a package to return the sample to them by FED EX or UPS. You can not use the post office to send gasoline samples. Once the lab gets the sample the test is completed and results are emailed to you within 24 hours.
