- Hey in the car i just bought it take 5w20. The previous owner said be put semi synthetic at the dealer.
- Now im putting full synthetic mobil1
- Will it damage the seals or anything put full synthetic? It's only 61k miles btw
if the oil meets or exceeds the oil specifications in your manual then you're fine.
Full synthetic is preferred or even required nowadays in newer engines. It provides a better lubrication film than regular or blend oils because the perfectly sized oil molecules are engineered (hence the name synthetic), not refined from crude. You don't NEED to use fully synthetic in a car that doesn't specify it, but you CANNOT put regular/blend in a car that specifies full synthetic (this is part of the manufacturer's standards). Regardless of regular/blend/synthetic you need to make sure the oil meets the vehicle manufacturer's standards and oil rating.
@razmigb
that's nonsense. Synthetic oil comes from crude.
EDIT: HIGHLY refined crude oil used as a base WITH engineered compounds. More quality control compared to regular...
That's right it has better lubricating properties. The biggest benefit of synthetic oil is that it maintains ideal viscosity over a wider range of temperatures. So when you start your vehicle cold in the morning , the oil moves quicker to coat the engine parts. And when the engine gets hotter, it maintains its film strength. It also stable over a longer period of time, which is why we can use longer change intervals.
