recently i seem to have consumed myself into oil research and brand snobbery. must be the darker nights.
i have the same engine in my UK car as the Chevrolet cruze, being the 1.4luv turbo unit.
The manufacturer oil recommendation for this engine is for one that helps againt LSPi. therefore i started doing quite a bit of research and found that Amsoil signature series 5w30, (although not actually having the dexos1 gen2 licence) seemed to tick the required boxes, on paper its spec sheet was favourable.
recently though here in the UK, amsoil has been getting harder to obtain, so i have been looking at other brands, but for some reason my head is saying "NO" and to stick with Amsoil as its a known quality brand.
should i be sticking with the brand name or is it fine to pick another brand as long as it meets the approved specs required.
i do my oil changes every 6-7000 miles, so i am wondering if Amsoil is overkill for this engine
