I have a VX Series 1 SS with Gen III V8 and use BP Pulp 98 octane. It is eight cents a litre more, so I would like to know if I am getting more than a small improvement in economy. The engine has only done 21,000 km, but I would think it is well run in by now.
Holden calibrated the Gen III to run on regular unleaded, so you are paying for a marginal increase in performance and fuel consumption, at best in the order of 2-3 per cent. The best way to check the value of running Pulp is to do a consumption test with both fuels. That way you will know the real benefits, or otherwise, in your own actual driving conditions.
