shell optimax

[alan pritchard]

what does anyone know about this stuff, all i can find out is it is higher octane than unleaded, and it keeps your engine cleaner......  the website claims that two cars the same, 1 on normal unleadede, 1 on optimax, overtaking a lorry, the one on optimax will get 3 lengths ahead of the other.  unfortunately it doesnt say what these cars are,  could be 500hp monstors, in which case it doesnt warrant using it.  i presume the only benefits it has is its octane rating.  any other info anyone??
