Funny how car maintenance works

[chevyjaxon]

dealerships suck i took my car to ford for a tune up (no time to diy) told them to change the oil now my car is 250 000 plus kilometers old so what do they do? put in 5w30 instead of 10w30 well when i got my car back it was burning oil like crazy all they told me was that was the ford approved viscosity for that V8 geez the car never burned oil before that so later that day i spent the money bought new oil (10w30) and did another oil change myself end result 100 dollars to ford for nothing and another 40 bucks to fix their mistake
