Q: Oil leak

asked by on

My car is leaking oil not a lot but it still leaks I use 10W30 synthetic oil in my car if I were to switch to conventional oil would it still leak as bad

My car has 140000 miles.
My car has an automatic transmission.

Hi there. Believe it or not, changing from synthetic to conventional could increase the leak. Although the viscosity of oil is similar in 10W30, synthetic oil tends to be a bit thicker in general.

The best suggestion is to contact one of our local mechanics who can find and repair the source of your oil leak.
