Are 5w And 0w Oils Too Thin?

[Rippthrough 98]

Just reading this and I thought I'd point out that my last oil change was to 5w40 fully synthetic as thats all the garage I went to had. That was a about 2 months ago and the car has had a pretty bad oil leak since (Didn't leak before)

 

Could this be down to the engine not holding the thinner oil? or possibly an ill fitted oil filter?

 

The problems gone from a niggle to a major leak in the last weak, nearly ran the oil dry to the point I could see the oil pressure drop when pulling away from t junctions

 

Checking the oil every day now and topping it up until I can get it booked into a garage to get the leak fixed

 

 

Can't have read it very well then, it's not thinner!

Quite! Although I understood it was thinner at cold? Doesn't excuse why I though it would contribute to a leak when the car is up to temperature

Yeah, but its still far thicker when cold than it will be when its hot.
