Chrysler 300 premium unleaded
Asked by Derrick Kershaw, e-mail
I have recently bought a Chrysler 300 with the 5.7-litre petrol V8. The dealer recommends using premium unleaded but the manufacturer's handbook states that 91 RON is acceptable but 95 is preferred. A friend has been running his on 91 with no ill effects. What do you say?

You can run 91-octane regular unleaded without any ill effects, but to get the best out of the car it's better to run Premium unleaded.
