Shell Optimax - Keith Stockdale
I tried Shell Optimax after the thread a little while ago in my 1.8 Mondeo.

I must say that I noticed no difference at all except the increse in price!

You may not feel any difference in performance, but try working out the MPG before and after, you may be surprised!

Re: Shell Optimax - Keith Stockdale
No difference, 40MPG as usual

Does the 1.8 mondeo have a knock sensor to take advantage of higher octane fuel ? I don't think so.....

My old Polo runs really well on it and the price increase is more or less regained in better economy. It pulls far better from low revs.

It does work. More power, smoother and the engine appears to be improving with repeated use.
