Hi,
I am finalizing a deal to buy a 2011 Honda Fit Hybrid, the car is really good in terms of body, interior, engine and everything but the owner told me that he uses Kixx 20w50 oil on this car, however the User manual recommend 0w30 for all weathers. I was just curious that would 20w50 oil would have done any damage to the car, the current owner has drive probably driven this car 10,000 km in Pakistan since August 2014.
One of the reason sellers use heavier oils in their cars is to muffle engine noises of weaker engines, but I guess this is not the case here, that person just didn't know which oil to use.
Thanks in advance.
