the Castrol advert that has appeared on this site. - escort man
Claims extra 370 further miles per year with their 5W30 A1 magnatec. (extra to what? reduced petrol?, than needing to change the oil? engine wear?)

Also claims the molecules know exactly where to go as soon as you turn the key;

Are they suggesting their oil molecules are all some micro-engineered electronic artificial intelligence programed molecule that 'knows' what part of the engine it should cling onto to prevent the most wear and tear AKA a Michael Chrichton book titled 'Prey'.

Or is this just PR mumbo jumbo to let the mind numbed consumer think their oil is better than everyone elses, and that is in fact just pumped around the engine by the oil pump. The majority of my engine is alloy anyway, thus non-magnetic.

ASDA's own brand is also A1 spec, although 10W40 and hasnt let me down in 2 years of use (3 oil changes)

I suspect that a 5W30 would just leak out the seals of a 2000 plate engine anyway.

IIRC Castrol aren't allowed to use the 'magnetic molecules' advert claim in the USA because it's not proven for their Magnatec oil.

Allegedly. Mods may care to check this out before Castrol sue you for millions ;>)

the advert renders my modest laptop useless with IE maxing out the CPU.

It's caused me to disable "shockwave flash object", which has to be counter productive for the advertiser.

Maybe a better browser than IE7, or a better laptop than a 1.6g celeron with 512 meg of RAM will happen one day - but not just yet.

I'm starting to worry about you guys with fancy PC's as I have an old 500 Mhz P3 running XP & IE6 that copes fine with all these flashing adverts.

Castrol is a brand dear to any red-blooded old car freak, so I am disappointed that my pop-up filter (or whatever it is) prevents the ad from appearing on my screen.
