I picked up your products, Upper Cylinder Lubricant and Injector Cleaner, Power Steering Fix and Transmission Fix a few weeks ago in El Paso. I was driving a 2002 Pontiac Montana V6, 140K miles and idling a little rough. No tune-up for at least 60K miles. I live in Las Cruces, NM, and so before leaving town I needed to fill up with gas and so I added your Upper Cylinder Lubricant to a full tank, about 18 gallons. I am very impressed! Before leaving El Paso to travel back to NM, and within 15 min. of driving around the city, the standing idle smoothed out perfectly! Acceleration too seems to be very good. That stuff really works! Thanks again for great products!
