Hello everyone I am little confuse of oil brand i.e. Either go through the grade of oil or Brand..?? I got " Savsol Synth ( API SN 5W40 GF-5 ) RACETRACK" oil from a oil shop for 1370INR for 3.5 ltr . In between I have contacted to FASS mechanic who I know personally have suggested to only go through the Grade brand doesn't matters. I have read all the threats related to oil but have not here/ read about the Savsol brand, is it really sufficient to my GP 28,000 km done and this is third time of oil Change. Please suggest me either I moved forward through Savsol or move to other Reputed oil Brand (Gulf, Mobil, Shell..etc.)...??
