Greetings guys. I purchased a used 2001 Toyota Carina Ti (JDM) on 5AFE 1.5L engine which has around 60K miles only. Engine's in very good condition, no oil loss/burn/hesitation/leak/smoke issue. Previous owner took good care but don't know what oil he used- i only changed the oil twice since purchase 8 months ago. I tried Magnatec 10W40 semi-synth and then it's now on Q8 5w-40 fully syth.
I want to stick to one brand only from my next oil change onwards. I don't have the manual. I mostly drive urban- medium to heavy traffic, hot n humid weather. Engine has slight 'old sewing machine' type noise which, on Magnatech, was not there all that much. Should I stop using fully synth and stick to semi-syhth?
Please suggest. I'm from near India.
