Contacted technical help lines in Australia for Shell, Castrol, Penrite and they all say a mineral SAE 30 is preferable to a synthetic multi-grade 5W30: "...these small engines favor the more basic types of oils, they don’t like fully synthetic products as much as cars would. It’s a given when...

I was referring to the statements that the SAE 30 is better than a fully synthetic 5W30 in terms of engine protection.

Sorry erroneous double posting deleted.

Thanks for all the feedback! I was planning to use a fully synthetic 5W30 (which is what I use in my car) to avoid keeping two different grades of engine oil, and to use a fully synthetic engine oil in my mower, but after all the scare mongering I think I'll play it safe and stick to SAE 30 -...

I have a lawn mower for which SAE30/10W30 engine oil is recommended. I use fully synthetic 5W30 engine oil for my cars and once the lawn mower has been running after a couple of hours of running I'd like to change to 5W30 - if I understand the only difference is the start up will be easier (oil...

OK it looks like the consensus is Mobil 1 ESP 5W-30. I can get it cheaper if buying a 20litre drum rather than 5litres. Does anybody have any idea what the shelf life is as I am planning an extra oil change i.e. 6 monthly at 4litres a change i.e. 20 litres is two and a half years supply.

So would a fully synthetic 5W30 engine oil - even if not VW 504.000 approved e.g. Royal Purple HPS - not be better?

But Mobil 1 ESP 5W30 is not fully synthetic I believe?

I was thinking of using a fully synthetic 5W30 engine oil in a 1.4litre TSI turbo-charge VW petrol engine that normally requires a VW 504.000 approved oil (to protect the catalytic convertor apparently). Royal Purple HPS is not VW 504.000 approved but they assure me that it exceeds VW 504.000...
