Your questions answered by the dealer you can trust
You often champion the virtues of good petrol, particularly Shell. I agree that the company's premium unleaded is excellent but am not so sure about Optimax, which I started using in 2002. My 1991 Volvo 940S continued to run perfectly, as always, but its temperature gauge barely moved - even though I was towing a 16ft caravan. I solved the problem by returning to premium unleaded.
A 940 is a crude old battle-axe designed to survive Arctic winters and collisions with elks. Most readers report improvements on Optimax, but Ofcom has censured Shell for claiming performance benefits.
