The Peugeot oil spec is clear enough but I am looking for knowledgeable advice about whether to continue to use 0-30 for our 1.2 Puretech 130 as originally recommended or 0-20 which I have seen recommended recently. Is this because newer engines now have slightly different components or tolerances? Or is this because it is thought to be better for older engines as well? Or another reason?
(PS note to site manager - the Peugeot 'make/model' drop down list does not contain model 2008).

To be honest it could be either.
Berlingo #1 had a basic IDI diesel engine without a turbo. Last knockings of the XUD design in terms of the head and injection mechanism. At the date of manufacture 100% synthetic oil was a premium product and whatever was recommended was a few steps beyond the multigrades we used in cars in my youth.
Caught out when our local indy closed I took it to an In and Out place for and 'oil and filter' service and they really wanted to use full synthetic.
A forum specialising in PSA products might be a better bet. Is French Car Forum still going?

>> Or another reason?
Climate. In colder climes like ours the thinner oil offers more protection at startup.

My Astra has gone through three oil change specs since it left the factory. I use both the Shell and Comma oil checker websites to keep up to date. Stick your registration in and see what they say.
I wouldn't rely on a retailer site. ECP stuck with an out of date spec. for over a year, presumably because they had a warehouse full of it to shift. I guess lots of indies were sticking the old stuff in customers cars because that's what ECP supplied.

0W-20 is Toyota's recommendation for mine, but from a Toyota forum it was apparent main dealers were using 5w-30 bulk oil and claiming it was recommended, or they were ignorant. Oil sites say 5W-30, but Toyota say it is acceptable, but use 0W-20 at the next oil change.

I think part of the reason for the switch to thinner oils is emissions related. Thinner oil means marginally better mpg and therefore a marginal reduction in tailpipe emissions. I do worry how much weight is given to the environmental arguments vs engine longevity.

Good point Metropolis - thanks to all for comments. I'm far more interested in longevity than mpg, so I think I'll stick to 0-30 unless compelling evidence appears before its 40,000 mile change, which will be at least a year away as only 34k on the clock at present.
