Contradictory and funny, I know a mechanic friend (driving E36 M3) entering races everyweek ..

he changes the spark plugs and oil everyweek

For optimun performance no doubt, like F1 changes / rebuilds their engines after every race.

Not allowed to any more!

platinum or not I never see a spark plug going 80,000 miles..will degrade the performance and consume more petrol imho.. :-/

Yes indeed Cem, and by then they will be well clogged whatever they are made of!!

If a V6 is clogging plugs, then it probably needs more than just a service  

80k is too much in my opinion, I'm happier with 40k.

If you've just gone in for a 20k service Bob, that cambelt can't be too far away by now

Another 20k to go James.

Blimey...

On the spark plug issue mate, I would personally be really unhappy with it.

I bet they just couldn't be arsed to get the coil packs out....

They were actually quite prepared to go ahead and do it but as I know the guys there really well, they were trying to save me a bit of money on the extra labour charge and wanted my decision. As I'm a bit skint, I've now told them to leave them until next intermediate service.

Ah, in that case it's not so bad - I retract my comment

Must stop being so cynical about garages....

Can't say I blame you for that James, there's not many out there that I trust to work on my Mig.

What  After all those laps at very high revs, with maximum strain placed on all the engine's components and they cannot rebuild or replace the engine?! Not even replace piston rings?!

How about when they blow up?  Also how does the engine survive a whole F1 season without major "treatment" after millions/billions of rev's?

I am amazed Martin!   Tell me what they now have to do please.

The plugs will do 80K miles without issue.

What I do find is that they work loose before this happens!

And they are not platinum, they just have 4 electrodes so in theory last 4 times longer  

On my old renault safrane I blew a spark plug out (probably because I didn't tighten the sparky enough) - was towing the van at the time - going up steep hill with foot to floor suddenly mighty big bang - thought I'd blown a ring/valve - but engine kept going altho' made a mighty racket - towed the van  30 miles home on 3 cylinders which was a miracle - put new sparky in and engine ran as sweet as a nut but sad conclusion is that car is scrapped now so now I've got a miggy

Blimey Martin, that really does put the engines under test then!!

Thanks

I believe it is changing from 2 race meetings to 3 next season. :-/

You wont find many formula one engines with piston rings....or cams come to that!
