Assalamo Alaikum!
I have Cultus 2010 non Euro , was bought zero meter. Currently its ODO is 104,000+ so the next oil change is around the corner. Its currently giving me about 18+ avg on motorway while city average depends on day to day factors still its giving me around 12 to 14 within the city (Multan). I am using SGO Ultimate 10w40 API SM from a quiet long time. I am not a techni guy in oil field so dont know about oil grades eg: SM,SG etc.
So kindly give me your opinion should i continue with Ultimate as the vehicle has crossed 100,000 mark and its now became a 9 year old vehicle but still in very good condition both bodywise and engine wise.
Someone suggested me to start using Havoline , your precious opinion in this regard is highly recommended.
Also vehicle is reducing coolant slowly i top it up but again after some days or some 100km it reduce it again. A mechanic told me that the issue is with Radiator Cap Seal not with engine, kindly suggest me that should i replace the Radiator cap, if yes then should i go for Genuine from Suzuki Dealership or any reputed brand.
thanks in advance
Jazak Allah
