Have you just bought the car from these guys by the way?
worth changing the oil to 20W50 and see how it goes?
Interesting. What would the benefit of this be?
it's thicker, so if the engines worn it might not get past the seals/rings as much.
if you are going to scrap the engine/run into the ground, then might be worth as a temp fix
I tell you what we use at work with great success on bad burners/smokers
Wynn's oil treatment
It's basically glue in a can
Get it from Halfords, two tins of that and fill her up with fresh 20w50, if that don't slow it down I think you've got a hole in a piston![]()
