Anyone seen the new technologu from Alfa called multiair for the petrol engines
Basically the cam only works exhaust valves and electrcoincs do the rest
No lag and better efficiency on their turbo engines
They are going to patent it this time as they didnt do this with their derv common rail back in 1997

When they sort the diesel one of this (in a few years time), i'll chop my Mito in for one with Multiair 
Sounds like a good idea but I expect problems with it!

as you say it's a single cam with an actuator type unit to control the inlet
i've also read stuff about twin turbo engines in development 
pics of multiair:
And the first Alfa MiTo to use it:

I thought fiat/alfa were working on a 100k no service engine?

Why do Astra VXR's have a 20,000 mile service interval then (remembering its a high spec Vauxhall 2.0 Turbo engine....) 
My bikes's are every 4k, but if it doesn't break down till 8k, why change it?
Tbh, i don't think i've ever heard that in my life, ever.....

I'm positive that my mate with the Civic Sport told me the oil that's in it lasts for 100,000 miles as long as nothing goes wrong with it.
I was a bit dubious, but it is a Honda. Not sure about it though.

Cam-less engines have been in development for a long time, but creating reliable hyrdaulic actuators was always a problem and it saps up energy .
Be really interesting if they can make it work!

Oil doesnt really 'break down' as such, it gets contaminated with fuel and carbon.

Aye, thats why theres an oil degredation sensor.. it could be you only need to pop in for an oil and filter change and a safety check between each 21k

FOR IMMEDIATE RELEASE
6 October 2009
ALFA ROMEO TOPS SEPTEMBER SALES
Alfa Romeo’s sales resurgence in the UK continued unabated during September, with the Italian sporting car manufacturer recording one of the highest year-to-date increases of any brand, and among the highest percentage increase for the new registration month.
In an industry badly affected by the recession, Alfa Romeo recorded a remarkable 148.5% rise in 59 plate registrations for the month, to deliver nearly 2,000 new cars to UK customers.
These figures continue the Italian marque’s upward trend, with more than 7,135 new Alfa Romeos sold here in the year-to-date, up 40.4% on the same period last year.
The Alfa MiTo – the marque’s new sporty compact model – leads the way with sales, supported by the Alfa 159, Brera and Spider which have all contributed positively to the brand’s success.
Alfa Romeo UK Sales Director, Andrew Sproston says: “This is great news for all concerned. Our growth is in-line with the expectations and objectives we set out at the beginning of the year.

Alfa Romeo tops September sales…2
“The hard work and investment we have put into the restructure of this iconic brand is now starting to pay off, and has played a vital part in our improved sales. Across the board, Alfa Romeo is returning to its rightful position as a leading quality brand, and customers are taking note. Built up over the past few years, our new product range has been complemented by our improved dealer network, better training and servicing, and dedicated attention to customer care.”
Not only has the Italian sporting car brand recorded one of the largest month-to-date percentage increases in the UK market, Alfa Romeo is one of just three manufacturers to record an overall rise in sales during 2009 – an even more impressive achievement when the current economic climate is taken into consideration.
In September, Alfa Romeo’s market share was 0.54%, more than double (125% increase) its presence in the UK car market compared to September last year.

Most modern synthetics that are ester based have a 20,000+ mile service lifespan, thats come from silkolene themselves.
Its only on bikes where they are revving to 14k+ that the oils are under more pressure so need changing much more frequently. Even in a bike the oild are designed to last 10,000+ miles, its just most people go by the manufacturers 4-6k service intervals rather than the oil manufacturers recommendations.

Motorcycle oils also have friction modifiers for the wet-clutch setups which degrade after time.

Its because it saves people money higher service intervals means more likely to buy.
Your bike revs higher than most engines, so more wear and more metal particles in the oil = more wear.
I've seen it a million times, there is plenty of companies that can test your oil for you by post.
