Just want to share a few findings with regards to AmsOil Universal in Honda/Acura 5sp AT.
First of all I had acquired the car with 96,000km on the clock (~60,000mi) right away I drained the ATF and refilled with Z-1 then few days after I had drained it again. After this I did not notice any change in shifts; it still had a very noticeable "soft hammer" during 2-3 upshift and then under heavy accel from 4-5.
8,000km later I did another drain refill with Z-1 still no changes, maybe just maybe a bit softer 2-3 upshift.
Few thousand km laterI did 4th drain/refill with Z-1 again, and again not much of a change
Then at 119,000km I decided to drain and refill with AMSOIL universal, at that time I only noticed no deterioration in shifts 6,000km later I did another drain/refil with AMSOil, it was not untill few months later that I noticed a positive change in 2-3 upshift as well as a much better response 4-5 when I mushed it I even missed my exit to check the shifts under heavy accel slowing down to 60km/h and the flooring it untill I hit 140km/h .
My findings:
much smoother ****s under all conditions very rarrely do I get an upshift that resembles the upshift with Z-1. Overall very pleased with AMS product and I really did not like their stuff.
Ok a bit long winded but I can't help it hope this may kinda help a bit.
P.s.
I still have 3 bottles of Z-1 and plan to use it straight or mix
