IF U SWITCH TO SYNTHETIC ON YOUR HIGH MILEAGE CAR YOUR ENGINE IS GOING TO LEAK

>IF U SWITCH TO SYNTHETIC ON YOUR HIGH MILEAGE CAR YOUR ENGINE IS GOING TO LEAK

is there any truth to this?

if you put the thin shit in, it might leak more than it already did

any type of oil in a high mileage car will leak desu

Paper gaskets will start to leak nine times out of ten but any rubber seals should be ok

If you're a cheap fuck just replace the gaskets with anaerobic or silicone sealant

switched to synthetic with a 29 year old american v8 with 220k and it doesnt leak a drop anywhere

5w 30 Mobil 1 Synthetic High Mileage
My engine doesn't leak or consumes any noticeable amount of oil (2uz fe)

There really is no point in using synthetics unless
>your vehicle is specifically made for it
>you are in a very cold weather area
>you are extending your oil changes in accordance with your manufacturer's manual specifications
In terms of measurable lubrication effectiveness there is no difference between synthetics and conventionals

Who knows? But dirty old engines deserve dirty old oil.

every engine leaks

I believe it's a myth. It started when boomers classic cars started leaking and wouldn't take responsibility or think that a 50 year old engine seal went out. Immediately blames the new fancy oil.
