ok fellows here is some thing else to share.
doing experiments on the ride is what i love to do but keep it in safe margin
so lastly i started to use petromin ultra 7 (mineral oil) in the ride and it was infact good oil.
this time an old friend of mine who owns a motor oil agency asked me to go for synthetic oil. so couple of days earlier i went to his agency and then we chat there for the which oil to pour so finally we agree to put MOBIL 1 in the ride
here what it says on the 4 ltrs bottle:
mobil 1 with supersyn
fully synthetic oil.
fellows trust this word of mine, its just mind blowing engine oil, my ride is so so responsive on this oil that hard to explain.
personally recommend this oil to all u steermatic owners here.
here is the snap of the bottle,
