Hi, I have a two old bottles of Auto-RX from about 6 years ago. They been sitting in my garage. ( I live in Texas, so it "gits" hot). I want to go ahead and use them in a old 87 Dodge with a 318 in it and (guessing) about 150,000 miles on it.
Can I still use Auto-Rx® that has been in my garage for a couple of years? Auto-Rx® is a highly concentrated combination of ester-based cleaning components and has a thick consistency. Shake the bottle thoroughly before use. If the bottle is intact and the contents have not been contaminated by foreign substances, Auto-Rx® should remain viable for use. Auto-Rx® pours best at room temperature. THIS IS ON FAQ put bottle under hot water and shake it will be as good as the day it was made.
