Do you recommend using a higher grade petrol like Shell V-Power?
Having read your columns for many years I notice how you advocate the regular use of higher grade petrol. I have a Skoda Octavia Scout 1.8 TSI and inside the fuel door there is a label that says use 95 RON/91 ROZ. I have just seen that Shell V-Power claims 99 RON. Do you still recommend the higher grade? Also can I ask if it is OK to use mineral oil in the engine rather than fully synthetic as it is noisy on start up?

Yes. The higher octane gives more torque at low RPM and the additives keep the engine fuel system clean which is particularly important with a Direct Injected petrol engine like yours. The noise on start up might be the timing chain starting to fail. You can't fix this with oil. Probably needs a new chain.

Saloon shape but actually a practical hatchback. Far superior interior quality than previous model.
