Additives work best

Answered by Carsguide.com.au · 02 Aug 2007

CHECK the engine is a Toyota engine because Toyota was fitting the Holden 1.9-litre overhead-valve four-cylinder engine to the Corona at that time. The capacity you quote suggests yours has the ``misfire'' four in it. If it's a Holden engine the compression ratio was 8.7:1, but it's likely to be less than that now. If it runs well I'd continue to use unleaded with an additive.
