Synthetic oil is NOT thinner! Viscosity remain the same (almost, since they cannot be exactly identical) between the 2 types of oil!

Better do some research. It is thinner when hot and oil consumption goes UP in older engines compared to regular oil. This used to be on the label when synthetic oil came out.

Not only that if you have oil leaks like an older engine is likely to develop it leaks out faster too.

Loosing oil

Hello,

Though old thread, but I have noticed am loosing oil since I started using synthetic oil and Fram filters. My millage is about 130k, no sign of leakage and car runs well could the change to synthetic be the problem or Fram filters?

Regards

Subthetic oil tends to leak/burn more in an old engine as it is thinner at cold temps and flows better into small spaces even if viscosity is identical. If you want the synthetic oil for cold starts then go with a 0w40 instead of a 0w30. Based on your location I dint think your concern is cold start so just switch back to a conventional oil or go to a thicker viscosity
