You can............but the engine was designed to run on the higher grade.

I am happy to fill with lower grade if none other was available, but as a rule I always use the higher grade, luckily our local station is a BP with the good stuff.

Seek out a Shell petrol station and fill up with Shell V-Power Nitro+ which is 99 octane. I run my 2005 Gen1 Boxster 987S on it and it seems to love it!

Using 95 Ron fuel in your Porsche is not optimising the engine mapping either for fuel efficiency or performance. With 95 Ron fuels, carbon build-up on combustion chambers and valve stems over a period of time, leads to increased fuel consumption, emissions and loss of performance.

I use only Shell V-power whenever possible, failing that BP Ultimate or other premium brand 98 Ron+ fuels. The same for my 3 previous 987.1 and 987.2 Porsches, 2.7, 3.4 S and 3.4 R. Premium fuels keep the engine internals clean, as well as providing dynamic benefits.

When I collected my 718S Boxster from Stuttgart last September, the guy doing the handover, who had done handovers for over 20 years, told me that any fuel is fine as long as it's not the ethanol mix E10 that I could have bought in Germany.

A few on here will know a chap with a McLaren who uses "any fuel that makes it go!"

Damn! So that 98 Ron sticker inside the filler flap is just for show. []

You're in an upmarket restaurant ordering fine food. The somellier comes over and asks if he can suggest some wines to compliment the excellent meal to which you have just treated yourself. No, you reply, a bloke I talked to about this place said that wine is just wine, pretty much anything other than the Blue Nun I might have bought will do. We'll have a bottle of your house white and two glasses of tap water.

Aha..........you have been to my local restaurant then?

Shell is the best, I only use vpower.

cleaner engine higher octane why would you use anything else ?

if you love your car use shell

new cars with direct injection really need a cleaning petrol. Octane give you more power.

I have had issues with both BP and Tesco, so just cannot ever recommend it.
