Hello all. I need to get some info from you. I have a 2003 Durango with the 4.7 liter engine. I have always used M1 since day 1. Recently, after the gas price hikes I went to Wally World and bought some Supertech Synthetic oil. I am trying to save cash until the gas prices go down. I need to know from you all how good this oil really is. I am planning on keeping my truck for 10 years and I need to know if this synth oil is really going to help me. Is it godd enough is what I need to know and how it compares to M1.
TIA
