Sometimes I have ideas, and this is one for today...

Each time I think I might splash out on Super, I end up at a garage that doesn't sell it, but has LRP instead. Logic tells me it should have higher octane rating than ordinary UL, but how does it compare octane-wise with Super and Optimax, and more importantly will it harm the engine? (Griff 500 minus furry bits)

'It may not be lead, but it has other chemicals that take it's place & also destroy the catalyst.'

But what about cars that don't have catalysts? Besides, as every car made in the last 9.5 years (ie most of them), you'd think they'd put a warning on the pumps if the price of an error is an expensive new catalyst.

'There is however a slight difference when I treat myself to a tankful of real petrol!'

You mean Optimax or real leaded?

Just think what we could do with the 100 octane stuff they ran Spitfires on... mind you if WW2 happened tomorrow the lefties would still be bleating about pollution/friendly fire/damage to bunnies etc etc...

'I ran my wedge on LRP and it pinked itself pinkdom.'

How did that compare with plain UL though? Was it better or worse?

Obviously there's an inter-car difference cropping up here, as someone reported using LRP in a Griff 500 with no (noticeable) effects. If I tried a tankful as an experiment, would it do any harm?

Parked Griffy at the local Esso garage today. Unleaded at 71.9, LRP at 75.5 and Super at 81.9.

Oh well, what's four quid extra in the scheme of things?

Damn, there has to be a better way!
