I used to only fill the car everytime it reached the reserve mode. So althought the computer claimed it had fuel for 100+ km, the car becomes very annoying reminding me every 5 minutes that i am almost out of fuel.
One day, the car started losing strenght even on 1st gear i couldn't reach 2k rpm, and there was a warning saying engine problems. But after a while the car would work properly again.
I took to the shop, and the guy simply told me, just drive it until the computer says you only have fuel for 20 km. The tank has fuel particles that petrified, and would stall the engine every now and then, because i kept filling way too soon.
Fucking cars men....i must buy an old volvo from the 80'sor 90's. Done with this modern crap
