At this point I take this opportunity to ask for an advice: The most readily available brand where i live are: castrol, shell, total, mobil and motul (I'm purposely excluding boutique brands). For your experience which one of these brands brings the highest level of ZDDP in their 10w40 oil...

Thank you all for tour answers!! At this point i think that the best compromise would be to use a good quality 10w40 for all of them (given that the beetle could use It with no problem). I got fooled by the TDS of the 5w50 but, as i'm understanding, what's written is not taking care of the...

Where?

Of course i take them out only when there's no rain or snow. I think i'll go with 15w40, which Is widely available and cheap here. For the alfa i'll run 5w50 or 10w40 instead. No risk of making the engine "dirtier" with a mineral 15w40 instead of syntetic?

Is 15w40/50 good enough for Winter time? Where i live it's easy to be at 0c in Winter (± 5 deegres) and way over 30c in Summer. So i need an oil that can withstand this wide range of temperatures. Of course i change the oil once a year

Oh ok! I get that. So it is better to consider something like a 15w50 or a 10w40. I'm trying to find a common oil for my three oldtimer cars: Alfa Romeo 33, NSU Prinz 4 (600cc twin cylinder, air cooled) and a 1970 beetle that i'm in the process of buying. Alfa is made to run on 10w40 according...

Hi everyone from Italy! As the title says, I'm trying to understand if a good 5w50 oil could be considered a good "all-arounder" for European classic cars. Here in Italy, in the 70s, 20w50 was the recommended viscosity pretty much in every owner's manual of every car. Studying the TDS of most...
