I have driven my Suzuki GS-150 for 12000kms with Zic, Suzuki, Caltex, Shell oils over the time. But yesterday I went for Liquimoly 10w-40 Street 4T Oil for the first time. And the mechanic told me that this oil can be good for 2000km. How correct is this statement? Please anyone share his experience of this oil. Thanks

Which grade was you using before with all other brands 10W40 or 20W50??? & Liquimoly 10w40 is mineral or is a synthetic oil???

bro i was using 20w50 zic oil before that because of the summer. Why does it matter what I used in the past? My main question is What is the expected mileage of LiquiMoly Oil in Suzuki GS-150? 1000km or 2000kms

Liquimoly 10W-40 easily lasts around 2000 km in Suzuki GS 150 with oil filter change every 4000 km.

Bro if you used mostly 20W50 in past then you can not shift to any 10W40 oil if you used it then engine parts will start making noises+there is a big chance engine will start blowing

naeeem_98 (Naeem Amjad) 2017-10-04 17:44:42 +0500 #29

Brother in my understanding, 10W40 is for cold weather and 20W50 is for hot weather. And Bike is running smoothly not giving any kind of issue after shifting to 10W40. No engine noises no fire catching lol

Okay Thanks Brother!

How much kilometers your bike has done until now??

naeeem_98 (Naeem Amjad) 2017-10-06 11:27:56 +0500 #32

This is my first post. I have used caltex, zic, suzuki oil and 1 time shell oil in the past. In winter 10w40 and in summer 20w50.

hamikhan (hamikhan) 2017-10-06 15:21:40 +0500 #33

Bro there is no such kind of thing is written in bike,s owner manual to use 10W40 in winter & 20w50 in summer oil is like addiction so be careful+for engine safety be stick to one grade only all year

hassantahir2 (Hassan Tahir) 2017-10-06 15:44:42 +0500 #34

In owners manual it's written to use a 10W-40 oil regardless of weather conditions and i would say that 10W-40 is a all rounder oil.
I have been using Liquimoly 10W-40 in my GS from start never had any problems in winter's or summers.

naeeem_98 (Naeem Amjad) 2017-10-09 14:58:23 +0500 #35

Okay Brother I will stick to Liquimoly 10W40 onwards in my GS.

hamikhan (hamikhan) 2017-10-09 20:46:58 +0500 #36

Bro i need advice.i got Suzuki GS 150 and After 1st oil change at 1000 KM i used Mobil 1 Special - 20W50 Engine oil (someone misguided me) then i came to know that its not good to use 20W50 in new bikes.
now my bike has clocked 3500 KM, should i stick to 20W50 or use 10W40 ? Need an expert advice.

hamikhan (hamikhan) 2018-07-24 19:39:25 +0500 #39

You can use any 10W40 oil INSHA ALLAH there will be no problem & kindly be stick to one brand only & change it on every 1000km
