Don’t think they have Halfords in Sardinia!Just go to halfords, type in your vehicle in the oil advice computer, or ask staff, then buy thier own brand from the list advised.

Haha, didn't see that bit.Don’t think they have Halfords in Sardinia!
I wouldnt be flushing the engine, could cause trouble, thing is if the engine oil was reguraly changed
then the new oil will keep the engine going just fine, flushing won't add new life, it could loosen up carbon
that could damage the engine, could cause it to blow past the rings and that.
The synthetic oil will flow just fine in the old oil ports, its thinner at cold temprature like at start up, where
most of the engine wear takes place.
Changing the filter means a lot, as a clogged one will starve the engine of oil and wear will happen
at a fast rate.

I've read oil has a shelf life.. Weird considering it's fossil fuel, I've got a few odd gallons in the shed from various places, mate had a garage and gave me some from the barrel.
So it's been sitting around years, I use it for top ups now and then, wondering if it has 'gone off '.
They do. Unfiltered oil is less than damaging than no oil.Do cars not have a pressure relief valve to allow oil to bypass the filter if it blocks?
I won't go into fitting customer supplied parts, as that is a minefield, but using the wrong oil won't usually cause any immediate issues.I've read oil has a shelf life..

Also Does anyone who does not do their own oil changes buy and take the correct spec oil to the garage doing the change to make sure the right stuff is going in ?
My mate just used the oil he had in the barrel for everything, not sure of the spec. It was years ago.
Reason I ask is at a party last Christmas there was an oil discussion, two guys had new high end Audis and they were moaning about the price of the specific oils required. Two other guys there, one worked on police car maintenance, the other ex submarine engineer, now mot tester both scoffed that 'oil was oil' and they're just bieng had over..
The Audi guys mentioned that if owt went wrong under the warranty Audi could test the oil and wrong spec could void the warranty.
API is only one part of the spec now. You really need to find out the manufacturers recommended spec, and what oils have been tested to that spec.@Memmeddu.
You need to know the viscosity of oil required and the API rating.
After that it’s down the colour and cost

In the case of metal filters, the bypass valve is usually part of the filter. Elements filters it can be either a spring directly against the element, or a separate valve built into the housing.

It causes longer term issues. Things like cams failing on VW PD engines, wet timing belts failing, sumps filling with sludge. All those usually won't become apparent until 50-60k later.
My current employer is currently facing a multimillion pound liability over wrong oils being used, due to lazy mechanics and managers in certain workshops, who simply couldn't be bothered ordering the correct oil, and instead used whatever they had in bulk. When the vehicles fail, the first thing the dealers and manufacturer ask for, is the full vehicle service history, and what oils had been booked out.
API is only one part of the spec now. You really need to find out the manufacturers recommended spec, and what oils have been tested to that spec.
For example we used to stock a 10W40 for Mercs, but the current 5W30 Vauxhall oil we stock also meets that same Merc spec, so we stopped keeping the 10W40.
Then there was the older 5w40 vauxhall oil that also covered one of the VW specs, but if you ordered oil to the VW spec, you'd normally get a 5W30.
It's more about what additives the manufacturers spec now, than it is about viscosity and API spec.
so ask them what they are using then if theres a good cheaper alternativeManufacturer Recommends Selenia K20 10W40 oil
@Munkul you're right .
It would be fine with any oil ,I just want to make the engine happy using better oil ,and filters than what they recommend .
Selenia Is just money for nothing according with every mechanic I've told with
