I've recently topped up my oil as it was bone dry (again) & i put in about 3 litres (which was a bit much i think) I put it in because the oil still
wasn't showing above the lowest marker, even in the morning it was below the marker.
Today, the car felt really sluggish & at one put a load of white smoke came from the back, eventually i drove home, still with faint smoke coming from the back still feeling like crap.
The coolant is normal & the air filter is normal, it revs fine & the smoke seems to of died down. (i havn't driven it tho)
What could this be please?
Thanks.
