Almost everytime I have seen someone post up about blown older engine it is because they are following someone's bad advice and using 0W/40... I am sure most engine builders on here have more experience at putting together the pieces on what works and doesnt work. Sure they don't mind the ready supply of rebuilds that people using 0/40 is giving them though.

Otherwise fully is superior to semi -- a fully's molecular structure stays in grade for a longer period than semi or mineral oils. Also, the Subaru flat-4 engine likes the fully synth 100% Ester type oils.

Yes and no. If the engine is knackered, then a synthetic isn't going to magically make everything better, but if it's been well serviced, it may help you get a few thousand more miles out of it. Also, if you want to use the car on a track, it is worth changing to a synthetic as it will take a lot more abuse than a semi, so you don't need to change is too often. It can work out cheaper than a semi becauseof that

I would love to see some factual evidence on why a "0w" oil has damaged an engine, and how it did it.

read your operator manual! thats what its there for. my classic manual says i can use 5W-30, 10W-30 or 10W-40. it goes on to say that 5W-30 is not recommended for sustained high speed driving. too thin.
