2006 Suzuki swift fuel light Google Search

In a Suzuki of that age (assuming you have the OHC engine), the most likely culprit is a broken timing belt.

which engine?
gen 3 swift had these engines.
1.2 L I4 (petrol)
1.3 L I4 (petrol)
1.5 L I4 (petrol)
1.6 L I4 (petrol)
1.3 L I4 (diesel)
so which one? never work on any car engine, until you know what's there. if I open my hood and look up, there is a sticker there states ENGINE in this car, but that is USA< other countries, have stickers on fire wall or ?
if in USA the VIN has the engine code, but you never stated country.
suz has like 55 engines. but above is for swift.

which might you have.???

if this is a manual transmission it should take 80-90 weight gear oil,the same as in the differential.if its an automatic trans then us the manufactures required oil as with auto trans oil they have different additives that if the wrong one is put in it can cause problems.

the engine was flooded probly fuel regulator is bad

use can use 5W20W or 10W30W, it depends on the climate u live in and the type of driving you do, if you live in a moderate climate like the southwestern US then 10W30W, if u live in the midwest then 5W30W is better, any major brand will do.

most new car use 5w30 or 10w 30
