Q: Can I use 5W20 oil instead of 5W40

asked by on

The oil cap calls for 5W40 synthetic oil. I would like to know if 5W20 synthetic can be used?

My car has 38410 miles.
My car has an automatic transmission.

The quick answer is no you should not use 5w20 when 5w40 is recommended by manufacturer. The thinner oil may not lubricate the internal engine as designed. The turbo also needs synthetic oils to withstand the heat of the turbo.
