Armorol Nano Ultra Lube 100ml + Compression Booster 2 x 100ml – High-Power Triple Pack for Cars (Up to 1500cc) with High Oil Consumption – Max Performance, Max Efficiency

This used to be best product. but i doubt their performance now. Best to use with semi synthetic oil. I have a maruti ertiga diesel and with semi synthetic cruising at 140kmph is very smooth. beyond 140 its smooth but not as good as in 140. have used liquimoly ceratec which is not as smooth as this but engine revs very freely and cruising at 160 is good. but till 140 i feel this is much more smoother and i prefer this. and another advantage of this is engine feels smoother even after 10000kms without change in oil whereas ceratec calls out to change at 7000kms

Working great
