Your considering paying 180 Euros to changed your engine oil. Are you made of money. Yes there is a difference between the brands, some are bloody expensive and some are cheap. It,s a diesel, use cheap oil and change it more often.

I use Total 9000 fully synthetic, I reckon that it gives a small improvement in fuel economy especially in cold weather, starts easily even at minus 7C too.

You are. My advice would be to use a cheap semi synthetic or mineral oil and change it much more often. Using fully synthetic oils that are designed for 12,000 service intervals is a waste of money in a dirty diesel engine. The oil will be full of carbon flakes that chew your bearings long before 12,000 miles. Fully synthetic oil is for high reving hot running high stress petrol engines. Supplying it for lower reving diesels is a con trick in my book. But each to their own i suppose.

Pat,
I'm with the guys on this, originally used fully synthetic but was using so much between changes that after two services switched to semi-syn 50,000 miles ago. I use Halfords 10w40 semi synthetic diesel at about €20 for 5 litres after trade discount. About 18 litres does me 10,000 miles between services (I lose a lot through the breather and leak a bit through a seal). Engine ran faultlessly through the cold snap, starting easlily in -12 deg.

The same quality of oil sold by Halfrauds can be got for around £12.00 or less at factors. Anybody that buys a ANYTHING from Halfrauds is being ripped off in a big way. Son in law was quoted £108.00 for a battery for his car. I got him a Varta from my supplier £54.00. If you buy stuff from Halfrauds at their prices you need your bumps feeling. They are a complete and utter ripoff.

Fair enough Wammers, but that's not always the case over here where motor factors vary hugely in price. The ones supplying agri stuff seem best but its hit and miss. And in defence of halfrauds, their tools aren't that bad and they're open sundays 
But in general you are of course correct!

Lesson here then is always buy your stuff in the week, ready for Sunday. Must admit their tools look ok, how they would stand up to daily use is another matter. Halfrauds capless 5w side lamp bulbs £4.28 a pair. Factors 30p each. Halfrauds yellow 21w flasher bulbs £5.98 per pair. Factor 70p each. Bulbs in bulk boxes from factors a lot less, sides maybe 20p each flashers 40p each. Go figure.
Its recommended you use a semi synthetic anyway so why use non recommended oils? most oils exceed the recommendations anyway, so you never have to buy an expensive one, its just not justified, your Landy wont thank you for it, the trick with oil is to change as often as you can then you get the best from it, battery's can be bought very cheaply from main stealer's Daf (the people who do trucks) have the exact same battery they use on Land Rovers, only difference is you done have the expensive logo on it, keep your receipt, put it in a plastic bag and when you change your battery, but the receipt in the plastic back and put it under the battery as your fitting it, then you wont lose it, and with felt tip put the date you bought it on the side of the battery, i always do that and seem to get another battery for free because it will go tits up before the 3 year warranty has finished

There speaks a man who gets out a bit. Not like the Sunday mechanic who gets raped using the Halfrauds bits. "Where are you going"? "Just off the Halfrauds love to have a ragmans trumpet shoved up my bottom" Has anyone ever though WHY Halfrauds open on Sunday?

Yeah that will do the job. But change the filter and top up at 3,000 miles. But no need to use dear oil, don't know what you have available over there, but i can get good semi synthetic (ticks all the boxes) for about £12.00 for five litres from the factors, or a less if you buy it in 25 litre tubs.

The BMW M51 is not that much lower reving than the petrol engine in my old Volvo, however the crankshaft bearing journal diameter is greater to withstand the higher loadings of the diesel, therefore the surface speed of the bearing interface is actually as high or higher than the Volvo petrol engine plus the loading is higher.
You use your cheap oils, I prefer to use better synthetic oil formulated for use in diesels and still change it at 6K mile intervals rather than the longer intervals in the service schedule. Cheaper than a new engine.

Yeah but fully synthetic oil is not needed in your old Volvo. Maybe in a 400 hp Subaru or something running 8,000 rpm that's the sort of vehicles that need it, but not an old volvo. Fully synthetic oil is bloody good but it is not needed in a diesel engine. Semi synthetic if you must but mineral oil changed often works out a lot cheaper and does just the same job. Each to their own.
