go AceHardware buy it. im not selling it but i've done it on all my cars d

dis mostly works in DI engines, for FI engines the fuel itself will clean the carbons in valves, intake etc, so for FI engines do italian tuneup is enuf ledi

all modern cars are DI.
our car design recirculates the exhaust for better complete burning to reach better fuel economy, cleaner emissions (to comply to better emission standard).

problem is those re-circulation will clog up sensor, prevent smooth airflow, dirty intake valves plus others.

if u do it with engine flush will be better.

i cant believe my gf car pedal response can improve with only the engine treatment only.
but the engine should be in terrible shape cuz when i poured it into the engine oil cover, saw really nasty looking mud colour inside.

colour and texture is like this when i peep into the hole

your iswara is how old ? 25years old ??
oil leak out from where ?
