Just got a second hand 95' Proton Iswara 1.5, car mileage around 300k++, don't have info about the last maintenance. What engine oil will suit the car ?

Mineral 15w40 or Semi Synthetic 10w40.

which provides better fuel efficiency ?

Normal 1.5 car bro

Not much different.

Semi syn will give u better mileage compared to mineral bcz mineral is thicker, thus having heavier FC. But my advice for u, don't ever go below 10w40 for old engines bcz they need thicker oil to preserve the engine. Just my advice though. U can still go with semi syn for better FC

Thank for the reply =D Just got the car but don't know need to do maintenance or not for the engine and some other parts. How to know how many liter engine oil needed ?

confession,

if u just bought the car. its good to sent it to your mech to check and do a routine maintenance...so you will know ur car condition.

proton normally 4Litres +/- only

is it better for me to bring to proton service center or any shop will do ?

old car dun need go proton...go to a mech that you familiar, or ask your fren to recommend(if any)...

if i am u..i will

flush n replace new engine oil
flush n replace new gear/transmission fluid
flush n replace power steering fluid
replace timing belt(full set with water pump) - for safety reason better do this
fan belts - to check
flush n replace new brake fluid
if brake disc rotor n pads still ok, then can use back
if manual, flush n replace clutch fluid
flush n replace radiator with better coolant
clean n service battery terminal for better contact

Hey guys,
If I still got a liter of shell full syn 10-40, and want to downgrade to semi syn, can I still mix the remaining 1 liter, or should i just use the fresh can of semi syn.

most of the time i use only fully syn, from trusted brand

if ur own car, u can mix...my own car, i also mix.

Got any new oil for me to test...
Need to change oil for my fish liao...
Petro Canada 5w30 oil still got stock?

Anyone used Eneos Semi-Syn Eco-Touring 5w30 and the M7 Semi-Syn Super High Response Eco 5w30? Would like to gather some feedback between the two as I'm deciding which one to go for.

im using m7 super syn 5w30 in fairlady n perodua...so far so good
