Just an update to my ride running the Rotella t6 synthetic. It runs flawlessly. I had trans noises before on the old oil when i bought my Rubicon. It only had 900 miles on it. Changed out the oil and cleaned the filter, and ran chevron techron through two tanks of fuel and it's running like new. I had hard starting issues before, now you touch the starter and it's running perfect. I just went on a camping trip where we worked the transmission hard riding two up going up some long technical grades. It sounds so smooth and has that honda whine that i love. It shifts between drive, low and reverse like butter now also. I'll run it long term and i'll post back if i ever have a problem.
