I am not a specialist but from as far as I remember all "old polish spec" mechanics always told me: DO-NOT-PU-ANY-SYNTHETIC-OIL-IN-MALUCH! :)
Such a thing as Fiat 126p will never happen again to this planet... Love it.

I used to run on Castrol RS 10W-60 which is fully synthetic. It was the only oil (from what I've tried) that kept my engine going for longer. Most of group-a 126's in Rally-Cross where running on this stuff.

My view is that if you've just put together an engine using new gaskets and cleaned the old parts from old oil (or just using new parts) then fully synthetic is the right choise. But if your engine is say 50k miles old just stick to what you used before - switching to synthetic will only cause leaks.

I spoke to the Proietti guys regarding synthetic oils. Interestingly, they swear by it and use it on the 500s and 126s. Everyone has a different view on synthetic versus normal engine oils. We are no where near coming to a consensus on which oil is best. I think the bottomline is, as Pete126 states, it is a matter of personal choice. Having said that, we all seem to agree that one should avoid using cheap engine oils and change oil frequently to ensure engine longevity.

The winter low temperature were nearly two months, from -15 to -27 degrees celsius. So I put a semi-synthetic oil, API SL / CF 5W40 grade. I have no problem after that.

sorry to burst your bubble is because its cheap stuff recycled in china, all green oil is bad, comma classic 20/50 is green, same as halfords rubbish 20/50

best 20/50 oils are morris, miller or unipart, also castrol 20/50 (if u can find it)

I have started to use 10W-60 fully synth after reading that the Abarth specialists recommend it for the air cooled engines partly for the heat dissipation that Pete mentioned but also for it's robustness at the higher temperatures the air cooled engines run at . Expensive especialy if you buy it by the litre but look out for special offers at Halfords on 4 or 5 litre cans  ;)

I know in VW land they have a special 'aircooled' oil called beetle juice which is thinner than usual. With A/C engines relying on the oil for cooling, thick oil doesnt tend to do them much good as they cant circulate as freely to cool down. I know the 126 has its cylinders going up and down rather than a slightly tilted boxer as in a VW but it seems to make sense to avoid thick oils.  Personally i think if you have an oil leak you should be sorting it rather than trying to block it with a thicker oil!
