Sae 30 oil query.

[elflapo]

Afternoon all. Just picked this up in halfords but suspect I've not got standard sae 30 oil andceill need to head back and swap it. Any recommendations?

the 0W is the viscosity when cold so at start up it will get to all parts of the engine
the 30 part is the viscosity at 100C so it will cling to all parts when hot and have good film strength

the C rating says its ok for catalyst engines C2 C3 etc is the ash residue in the oil and you don't need to worry about that

I would use that without any hesitation your just buying a slightly better oil than you need

some interesting info here www.oilspecifications.org/acea.php

as tz says the weights ok , but i'd be more concerned about any detergents added to it , its for engines that run dry clutches . vespas run wet clutches , local builders merchants or garden centres will hold sae30 non-detergent in the lawnmower bit . £5 a litre from whykes . H
