What I'm wondering is, I'd want to do my own oil change now but the thing that stops be is that it is actually cheaper to give my mechanic $20 cash to do the oil lube and filter. I mean the oil he puts in is just generic 5w30 and a generic filter but hey for $20 he does the labour. Now If I were to do it, I think I'd lose money. If i put in the higher mileage oil, I'm looking at about $18 plus another $4 for the extra 1L. On top of that I'm out about $4-7 for the oil filter which comes up to $26-$30. A net loss of $10 per oil change, I know it's counting pennies, but as a student and with rising tuitions I need the extra cash. Now generic oil (still meets standards) is asbout $10 + the filter which leaves me saving $5 every oil change, or in my driving scenario about $5 bucks every 2 months or $60 a year. What should I do? is there a recommendation you guys can make on this topic?
